DashTable.dash_datatable — Method

dash_datatable(;kwargs...)

A DataTable component. Dash DataTable is an interactive table component designed for designed for viewing, editing, and exploring large datasets. DataTable is rendered with standard, semantic HTML <table/> markup, which makes it accessible, responsive, and easy to style. This component was written from scratch in React.js specifically for the Dash community. Its API was designed to be ergonomic and its behavior is completely customizable through its properties. Keyword arguments:

active_cell (optional): The row and column indices and IDs of the currently active cell.

row_id is only returned if the data rows have an id key.. activecell has the following type: lists containing elements 'row', 'column', 'rowid', 'column_id'. Those elements have the following types:

row (Real; optional)
column (Real; optional)
row_id (String | Real; optional)
column_id (String; optional)
columns (optional): Columns describes various aspects about each individual column.

name and id are the only required parameters.. columns has the following type: Array of lists containing elements 'clearable', 'deletable', 'editable', 'hideable', 'renamable', 'selectable', 'format', 'id', 'name', 'presentation', 'onchange', 'sortas_null', 'validation', 'type'. Those elements have the following types:

clearable (a value equal to: 'first', 'last' | Bool | Array of Bools; optional): If true, the user can clear the column by clicking on the clear

action button on the column. If there are multiple header rows, true will display the action button on each row. If last, the clear action button will only appear on the last header row. If first it will only appear on the first header row. These are respectively shortcut equivalents to [false, ..., false, true] and [true, false, ..., false]. If there are merged, multi-header columns then you can choose which column header row to display the clear action button in by supplying an array of booleans. For example, [true, false] will display the clear action button on the first row, but not the second row. If the clear action button appears on a merged column, then clicking on that button will clear all of the merged columns associated with it. Unlike column.deletable, this action does not remove the column(s) from the table. It only removed the associated entries from data.

deletable (a value equal to: 'first', 'last' | Bool | Array of Bools; optional): If true, the user can remove the column by clicking on the delete

action button on the column. If there are multiple header rows, true will display the action button on each row. If last, the delete action button will only appear on the last header row. If first it will only appear on the first header row. These are respectively shortcut equivalents to [false, ..., false, true] and [true, false, ..., false]. If there are merged, multi-header columns then you can choose which column header row to display the delete action button in by supplying an array of booleans. For example, [true, false] will display the delete action button on the first row, but not the second row. If the delete action button appears on a merged column, then clicking on that button will remove all of the merged columns associated with it.

editable (Bool; optional): There are two editable flags in the table.

This is the column-level editable flag and there is also the table-level editable flag. These flags determine whether the contents of the table are editable or not. If the column-level editable flag is set it overrides the table-level editable flag for that column.

hideable (a value equal to: 'first', 'last' | Bool | Array of Bools; optional): If true, the user can hide the column by clicking on the hide

action button on the column. If there are multiple header rows, true will display the action button on each row. If last, the hide action button will only appear on the last header row. If first it will only appear on the first header row. These are respectively shortcut equivalents to [false, ..., false, true] and [true, false, ..., false]. If there are merged, multi-header columns then you can choose which column header row to display the hide action button in by supplying an array of booleans. For example, [true, false] will display the hide action button on the first row, but not the second row. If the hide action button appears on a merged column, then clicking on that button will hide all of the merged columns associated with it.

renamable (a value equal to: 'first', 'last' | Bool | Array of Bools; optional): If true, the user can rename the column by clicking on the rename

action button on the column. If there are multiple header rows, true will display the action button on each row. If last, the rename action button will only appear on the last header row. If first it will only appear on the first header row. These are respectively shortcut equivalents to [false, ..., false, true] and [true, false, ..., false]. If there are merged, multi-header columns then you can choose which column header row to display the rename action button in by supplying an array of booleans. For example, [true, false] will display the rename action button on the first row, but not the second row. If the rename action button appears on a merged column, then clicking on that button will rename all of the merged columns associated with it.

selectable (a value equal to: 'first', 'last' | Bool | Array of Bools; optional): If true, the user can select the column by clicking on the checkbox or radio button

in the column. If there are multiple header rows, true will display the input on each row. If last, the input will only appear on the last header row. If first it will only appear on the first header row. These are respectively shortcut equivalents to [false, ..., false, true] and [true, false, ..., false]. If there are merged, multi-header columns then you can choose which column header row to display the input in by supplying an array of booleans. For example, [true, false] will display the selectable input on the first row, but now on the second row. If the selectable input appears on a merged columns, then clicking on that input will select all of the merged columns associated with it. The table-level prop column_selectable is used to determine the type of column selection to use.

format (optional): The formatting applied to the column's data.

This prop is derived from the d3-format library specification. Apart from being structured slightly differently (under a single prop), the usage is the same. 'locale': represents localization specific formatting information. When left unspecified, will use the default value provided by d3-format. The keys are as follows: 'symbol': (default: ['$', '']) a list of two strings representing the prefix and suffix symbols. Typically used for currency, and implemented using d3's currency format, but you can use this for other symbols such as measurement units; 'decimal': (default: '.') the string used for the decimal separator; 'group': (default: ',') the string used for the groups separator; 'grouping': (default: [3]) a list of integers representing the grouping pattern. 'numerals': a list of ten strings used as replacements for numbers 0-9; 'percent': (default: '%') the string used for the percentage symbol; 'separate4digits': (default: True) separate integers with 4-digits or less. 'nully': a value that will be used in place of the nully value during formatting. If the value type matches the column type, it will be formatted normally. 'prefix': a number representing the SI unit to use during formatting. See `dashtable.Format.Prefix` enumeration for the list of valid values 'specifier': (default: '') represents the rules to apply when formatting the number. dash_table.FormatTemplate contains helper functions to rapidly use certain typical number formats.. format has the following type: lists containing elements 'locale', 'nully', 'prefix', 'specifier'. Those elements have the following types:

locale (optional): . locale has the following type: lists containing elements 'symbol', 'decimal', 'group', 'grouping', 'numerals', 'percent', 'separate_4digits'.

Those elements have the following types:

symbol (Array of Strings; optional)
decimal (String; optional)
group (String; optional)
grouping (Array of Reals; optional)
numerals (Array of Strings; optional)
percent (String; optional)
separate_4digits (Bool; optional)
nully (Bool | Real | String | Dict | Array; optional)
prefix (Real; optional)
specifier (String; optional)
id (String; required): The id of the column.

The column id is used to match cells in data with particular columns. The id is not visible in the table.

name (String | Array of Strings; required): The name of the column,

as it appears in the column header. If name is a list of strings, then the columns will render with multiple headers rows.

presentation (a value equal to: 'input', 'dropdown', 'markdown'; optional): The presentation to use to display the value.

Defaults to 'input' for ['datetime', 'numeric', 'text', 'any'].

on_change (optional): The on_change behavior of the column for user-initiated modifications.

'action' (default 'coerce'): none: do not validate data; coerce: check if the data corresponds to the destination type and attempts to coerce it into the destination type if not; validate: check if the data corresponds to the destination type (no coercion). 'failure' (default 'reject'): what to do with the value if the action fails: accept: use the invalid value; default: replace the provided value with validation.default; reject: do not modify the existing value.. on_change has the following type: lists containing elements 'action', 'failure'. Those elements have the following types:

action (a value equal to: 'coerce', 'none', 'validate'; optional)
failure (a value equal to: 'accept', 'default', 'reject'; optional)
sort_as_null (Array of String | Real | Bools; optional): An array of string, number and boolean values that are treated as null

(i.e. ignored and always displayed last) when sorting. This value overrides the table-level sort_as_null.

validation (optional): The validation options.

'allownull': Allow the use of nully values. (undefined, null, NaN) (default: false) 'default': The default value to apply with onchange.failure = 'default'. (default: null) 'allowYY': datetime columns only, allow 2-digit years (default: false). If true, we interpret years as ranging from now-70 to now+29 - in 2019 this is 1949 to 2048 but in 2020 it will be different. If used with action: 'coerce', will convert user input to a 4-digit year.. validation has the following type: lists containing elements 'allownull', 'default', 'allow_YY'. Those elements have the following types:

allow_null (Bool; optional)
default (Bool | Real | String | Dict | Array; optional)
allow_YY (Bool; optional)
type (a value equal to: 'any', 'numeric', 'text', 'datetime'; optional): The data-type of the column's data.

'numeric': represents both floats and ints. 'text': represents a string. 'datetime': a string representing a date or date-time, in the form: 'YYYY-MM-DD HH:MM:SS.ssssss' or some truncation thereof. Years must have 4 digits, unless you use validation.allow_YY: true. Also accepts 'T' or 't' between date and time, and allows timezone info at the end. To convert these strings to Python datetime objects, use dateutil.parser.isoparse. In R use parse_iso_8601 from the parsedate library. WARNING: these parsers do not work with 2-digit years, if you use validation.allow_YY: true and do not coerce to 4-digit years. And parsers that do work with 2-digit years may make a different guess about the century than we make on the front end. 'any': represents any type of data. Defaults to 'any' if undefined. NOTE: This feature has not been fully implemented. In the future, it's data types will impact things like text formatting options in the cell (e.g. display 2 decimals for a number), filtering options and behavior, and editing behavior. Stay tuned by following https://github.com/plotly/dash-table/issues/166s

include_headers_on_copy_paste (Bool; optional): If true, headers are included when copying from the table to different

tabs and elsewhere. Note that headers are ignored when copying from the table onto itself and between two tables within the same tab.

locale_format (optional): The localization specific formatting information applied to all columns in the table.

This prop is derived from the d3.formatLocale data structure specification. When left unspecified, each individual nested prop will default to a pre-determined value. 'symbol': (default: ['$', '']) a list of two strings representing the prefix and suffix symbols. Typically used for currency, and implemented using d3's currency format, but you can use this for other symbols such as measurement units. 'decimal': (default: '.') the string used for the decimal separator. 'group': (default: ',') the string used for the groups separator. 'grouping': (default: [3]) a list of integers representing the grouping pattern. 'numerals': a list of ten strings used as replacements for numbers 0-9. 'percent': (default: '%') the string used for the percentage symbol. 'separate4digits': (default: True) separate integers with 4-digits or less.. localeformat has the following type: lists containing elements 'symbol', 'decimal', 'group', 'grouping', 'numerals', 'percent', 'separate_4digits'.

Those elements have the following types:

link_target (String | a value equal to: 'blank', 'parent', 'self', 'top'; required)
css (optional): The css property is a way to embed CSS selectors and rules

onto the page. We recommend starting with the style_* properties before using this css property.

Those elements have the following types:

selector (String; required)
rule (String; required)s
data (Array of Dicts; optional): The contents of the table.

The keys of each item in data should match the column IDs. Each item can also have an 'id' key, whose value is its row ID. If there is a column with ID='id' this will display the row ID, otherwise it is just used to reference the row for selections, filtering, etc. Example: [ {'column-1': 4.5, 'column-2': 'montreal', 'column-3': 'canada'}, {'column-1': 8, 'column-2': 'boston', 'column-3': 'america'} ]

data_previous (Array of Dicts; optional): The previous state of data. data_previous

has the same structure as data and it will be updated whenever data changes, either through a callback or by editing the table. This is a read-only property: setting this property will not have any impact on the table.

data_timestamp (Real; optional): The unix timestamp when the data was last edited.

Use this property with other timestamp properties (such as n_clicks_timestamp in dash_html_components) to determine which property has changed within a callback.

editable (Bool; optional): If True, then the data in all of the cells is editable.

When editable is True, particular columns can be made uneditable by setting editable to False inside the columns property. If False, then the data in all of the cells is uneditable.

they remain visible when scrolling vertically down the table. fixed_rows fixes rows from top-to-bottom, starting from the headers. If headers is False, no rows are fixed. If headers is True, all header and filter rows (see filter_action) are fixed. Additional data rows can be fixed by assigning a number to data. Defaults to { headers: False }. Note that fixing rows introduces some changes to the underlying markup of the table and may impact the way that your columns are rendered or sized. View the documentation examples to learn more.. fixed_rows has the following type: lists containing elements 'headers', 'data'. Those elements have the following types:

column_selectable (a value equal to: 'single', 'multi', false; optional): If single, then the uer can select a single column or group

of merged columns via the radio button that will appear in the header rows. If multi, then the user can select multiple columns or groups of merged columns via the checkbox that will appear in the header rows. If false, then the user will not be able to select columns and no input will appear in the header rows. When a column is selected, its id will be contained in selected_columns and derived_viewport_selected_columns.

row_deletable (Bool; optional): If True, then a x will appear next to each row

and the user can delete the row.

cell_selectable (Bool; optional): If True (default), then it is possible to click and navigate

table cells.

and not have borders between the columns.

page_action (a value equal to: 'custom', 'native', 'none'; optional): page_action refers to a mode of the table where

not all of the rows are displayed at once: only a subset are displayed (a "page") and the next subset of rows can viewed by clicking "Next" or "Previous" buttons at the bottom of the page. Pagination is used to improve performance: instead of rendering all of the rows at once (which can be expensive), we only display a subset of them. With pagination, we can either page through data that exists in the table (e.g. page through 10,000 rows in data100 rows at a time) or we can update the data on-the-fly with callbacks when the user clicks on the "Previous" or "Next" buttons. These modes can be toggled with this page_action parameter: 'native': all data is passed to the table up-front, paging logic is handled by the table; 'custom': data is passed to the table one page at a time, paging logic is handled via callbacks; none: disables paging, render all of the data at once.

page_current (Real; optional): page_current represents which page the user is on.

Use this property to index through data in your callbacks with backend paging.

page_count (Real; optional): page_count represents the number of the pages in the

paginated table. This is really only useful when performing backend pagination, since the front end is able to use the full size of the table to calculate the number of pages.

page_size (Real; optional): page_size represents the number of rows that will be

displayed on a particular page when page_action is 'custom' or 'native'

dropdown (optional): dropdown specifies dropdown options for different columns.

filter_query (String; optional): If filter_action is enabled, then the current filtering

string is represented in this filter_query property.

filter_action (optional): The filter_action property controls the behavior of the filtering UI.

If 'none', then the filtering UI is not displayed. If 'native', then the filtering UI is displayed and the filtering logic is handled by the table. That is, it is performed on the data that exists in the data property.

(e.g. sort by country, sort within each country, sort by year) or by a single column. NOTE - With multi-column sort, it's currently not possible to determine the order in which the columns were sorted through the UI. See https://github.com/plotly/dash-table/issues/170

sort_by (optional): sort_by describes the current state

of the sorting UI. That is, if the user clicked on the sort arrow of a column, then this property will be updated with the column ID and the direction (asc or desc) of the sort. For multi-column sorting, this will be a list of sorting parameters, in the order in which they were clicked.. sortby has the following type: Array of lists containing elements 'columnid', 'direction'. Those elements have the following types:

column_id (String; required)
direction (a value equal to: 'asc', 'desc'; required)s
sort_as_null (Array of String | Real | Bools; optional): An array of string, number and boolean values that are treated as null

(i.e. ignored and always displayed last) when sorting. This value will be used by columns without sort_as_null. Defaults to [].

style_data (Dict; optional): CSS styles to be applied to each individual data cell.

That is, unlike style_cell, it excludes the header and filter cells.

style_filter (Dict; optional): CSS styles to be applied to the filter cells.

Note that this may change in the future as we build out a more complex filtering UI.

style_header (Dict; optional): CSS styles to be applied to each individual header cell.

That is, unlike style_cell, it excludes the data and filter cells.

style_cell_conditional (optional): Conditional CSS styles for the cells.

This can be used to apply styles to cells on a per-column basis.. stylecellconditional has the following type: Array of lists containing elements 'if'. Those elements have the following types:

style_header_conditional (optional): Conditional CSS styles for the header cells.

This can be used to apply styles to header cells on a per-column basis.. styleheaderconditional has the following type: Array of lists containing elements 'if'. Those elements have the following types:

if (optional): . if has the following type: lists containing elements 'columnid', 'columntype', 'headerindex', 'columneditable'.

Those elements have the following types:

header_index (Real | Array of Reals | a value equal to: 'odd', 'even'; optional)
column_editable (Bool; optional)s
virtualization (Bool; optional): This property tells the table to use virtualization when rendering.

Assumptions are that: the width of the columns is fixed; the height of the rows is always the same; and runtime styling changes will not affect width and height vs. first rendering

derived_filter_query_structure (Dict; optional): This property represents the current structure of

filter_query as a tree structure. Each node of the query structure has: type (string; required): 'open-block', 'logical-operator', 'relational-operator', 'unary-operator', or 'expression'; subType (string; optional): 'open-block': '()', 'logical-operator': '&&', '||', 'relational-operator': '=', '>=', '>', '<=', '<', '!=', 'contains', 'unary-operator': '!', 'is bool', 'is even', 'is nil', 'is num', 'is object', 'is odd', 'is prime', 'is str', 'expression': 'value', 'field'; value (any): 'expression, value': passed value, 'expression, field': the field/prop name. block (nested query structure; optional). left (nested query structure; optional). right (nested query structure; optional). If the query is invalid or empty, the derived_filter_query_structure will be null.

component_name (String; optional): Holds the name of the component that is loading
persistence (Bool | String | Real; optional): Used to allow user interactions in this component to be persisted when

the component - or the page - is refreshed. If persisted is truthy and hasn't changed from its previous value, any persisted_props that the user has changed while using the app will keep those changes, as long as the new prop value also matches what was given originally. Used in conjunction with persistence_type and persisted_props.

persisted_props (Array of a value equal to: 'columns.name', 'data', 'filterquery', 'hiddencolumns', 'selectedcolumns', 'selectedrows', 'sort_by's; optional): Properties whose user interactions will persist after refreshing the
