Table
Tables are used to present structured data content, usually accompanied by the ability to manipulate the data (sort, search, paginate...).
How to Use
Into the header.
columns
And data. DataSource
To render.Please provide a "key" for each data item in the dataSource that is different from the value of the other data items, or use the row Key parameter to specify an attribute name as the primary key, alternative row operation functions such as row selection and expansion of the table.
Demos
Basic Table
For tables, the two most basic parameters are
dataSource
and columns
, the former is the data item, the latter is the configuration of each column, both are array types.JSX Writing
You can also use JSX syntax definitions
columns
, note that Table only supports columns
JSX syntax definition. You cannot use any component package Table.Column
.Note: JSX-written tables are not supported the parameterResizable
.
Notice
When columns are written in JSX, please do not use it at the same time as the configuration method; if used at the same time, only the configuration method will take effect, and no aggregation operation will be performed.
Row Selection Operation
This feature can be turned on by passing in
rowSelection
.- Click the selection box in the header, and all rows in the
dataSource
that are not in the state ofdisabled
will be selected. The callback function for selecting all rows isonSelectAll
; - Clicking on the row selection box will select the current row. Its callback function is
onSelect
;
Note: Be sure to provide a "key" for each row of data that is different from other row values, or use the rowKey parameter to specify a property name as the primary key.
Custom Rendering
Users can use Column.render to customize the rendering of a column of cells, which is suitable for rendering more complex cell content.
Table With Pagination
Table paging currently supports two modes: controlled and uncontrolled.
- In controlled mode, the paging state is passed entirely externally, depending on whether the pagination .currentPage field is passed. In general, the controlled mode is suitable for remotely pulling data and rendering.
- In uncontrolled mode, Table passes the incoming dataSource length as total to the Pagination component by default, and of course you can also pass a total field to overwrite the value of the Table component, but we do not recommend users to pass this field in uncontrolled paging mode.
Note: The custompagination.total
field passed in uncontrolled conditions is supported only after version 0.25.0.
Pull Remote Data
Under normal circumstances, the data is often not obtained at one time. We will retrieve the data from the interface when clicking on the page number, filter or sort button. In this case, please use Controlled mode To handle pagination. The user needs to pass in the
pagination.currentPage
field, where the rendering of the pagination component depends entirely on the incoming pagination object.Notice
1. When pagination is an object type, literal is not recommended because it causes the table to render to its original state (it looks like the pager is not working). Please try to define reference type parameters outside the render method. If hooks are used, please use useMemo or useState for storage.
2. In the controlled mode, Table will not paginate dataSource, please pass in current page data to dataSource
Fixed Column or Head
You can fix the column by setting the Fixed attribute of the column and scroll.x, and fix the header by setting scroll.y.
- Make sure that all elements inside the table do not affect the height of the cells after rendering (e.g. containing unloaded pictures, etc.). In this case, give the stator element a definite height to ensure that the left and right Fixed columns of cells are not deranged.
- If the column header is not aligned with the content or there is a column duplication, specify the width width of the fixed column. If the specified width is not effective, try to recommend leaving a column with no width to accommodate the elastic layout, or check for ultra-long continuous fields to destroy the layout.
- It is recommended to specify scroll.x as a fixed value or percentage greater than the width of the table. It is recommended to set a fixed value of
>= the sum of all fixed column widths + the sum of all table column widths
.
The header can be fixed to the top of the page with the
sticky
property. v2.21 version support. When passing top
, you can control the distance from the scroll container.标题 | 大小 | 所有者 | 更新日期 |

Table Header With Sorting and Filtering Function
Filters and sorting controls are integrated inside the table, and users can pass in the sorter display of the sorter open header by passing filters in Column and the filter control display of the onFilter open header.
Note: Be sure to provide a "key" for each row of data that is different from other row values, or use the rowKey parameter to specify a property name as the primary key.
Custom Filter Item Rendering
Since the 1.1.0 version, it is supported to pass in
renderFilterDropdownItem
to customize the rendering method of each filter item.This method accepts an
Object
input parameter, and the meaning of each attribute is as follows:onChange: e => void
current filter item selection/reverse selection event;text: ReactNode
copy of the current screening item;value: any
the value of the current filter item;checked: boolean
whether the current filter item has been selected;filteredValue: any[]
all currently filtered values;level: number
is the level of the current filter item, if it is a nested filter item, the value will be >= 1;filterMultiple: boolean
whether the current filter item is multi-select.
A Table That Can Be Expanded
Note
1. Since version `0.27.0`, the unfold button will be rendered in the same cell as the first column, and you can open a separate column of rendering by passing in `hideExpandedColumn = `.
2. Be sure to provide a "key" for each row of data that is different from the other row values, or use the rowKey parameter to specify an attribute name as the primary key.
A Common Table That Can Be Expanded
If you need to render a table that can be expanded, in addition to the need to pass
expandedRowRender
In addition to this method, you must specify rowKey
(by default key
), Table will be based on rowKey
Gets a row unique identifier.- If
rowKey
is a Function, the result ofrowKey(record)
is taken as the row unique ID - If
rowKey
is a string type, you takerecord[rowKey]
as the row unique ID
The Unfold Button Is Rendered In a Separated Column
Version: >= 0.27.0
By default, the expansion button will be rendered in the same cell as the first copy, and you can enter
hideExpandedColumn={false}
to render as a separate column:Turn Off Rendering of Expandable Button of a Row
Version: > = 0.27.0
You can pass the row Expandable method, enter the reference as record, and determine whether the return value is false to close the rendering of the expandable button on a row.
Tree Data Display
Version: > = 0.27.0
The table supports the display of tree data and is automatically displayed as a tree table when there are children fields in the data. If you do not need or use other fields, you can configure it with the childrenRecordName. In addition, you can control the indent width of each layer by setting indent Size.
Note: Be sure to provide a "key" for each row of data that is different from the other row values, or use therowKey
parameter to specify a property name as the primary key.
Simple example of tree data
Rows of Interchangeable Tree Data
Version: > = 0.27.0
You can do row switching by changing the order of the dataSource elements.
Tree Selection
Version: >=0.27.0
By default, the row selection of the table is independent. You can simulate a tree selection by defining selectedRowKeys.
Custom Row or Cell Events and Properties
- The incoming
onRow
/onHeaderRow
can define the native event or property of a table or table header line. - The incoming
Column.onCell
/Column.onHeaderCell
can define a table or header cell native event or property.
In principle, the properties or events supported on tr / td / th can be defined. For example:
- The tr at the head of the watch defines onMouseEnter / onMouseLeave
- The tr of the table defines className
- The third line of the table defines onClick.
Zebra Pattern Table
Use
OnRow
to set a background color for each row to create a zebra stripped table.Resizable Column
Version > = 0.15.0
Basic Resizable Column
For some columns with more content, you can choose to turn on the telescopic column function and pull and pull at the head to realize the real-time change of column width.
But you need to pay attention to some parameters:
resizable
is set totrue
or anobject
- Any column in
columns
that requires a telescopic function should specify thewidth
field (if not passed, the column does not have a telescopic function and its column width will be automatically adjusted by the browser)
It is not recommended to use with fixed columns at the same time. Fixed columns need to specifyscroll.x
, which stipulates that the table has a width range, and the flexible column will expand the column width, which may cause the table to be misaligned
Advanced Telescopic Columns
resizable
can also be an object
, including three event methods:- onResize
- onResizeStart
- onResizeStop
These three callback will be triggered on
changing column width
, start changing column width
and stop changing column width
respectively. Developers can choose to modify the column at this time, such as adding a vertical line effect when dragging, as shown below.The CSS style definition used in this example:
Drag Sorting
With custom elements, we can integrate
react-dnd
To implement drag and drop sorting.The CSS styles used in this example are:
Table Grouping
For some tables whose data needs to be displayed in groups, you can pass in
groupBy
to define the grouping rules, and use renderGroupSection
to define the rendering of the grouping table header.Note: Be sure to provide a "key" for each row of data that is different from other row values, or use the rowKey parameter to specify a property name as the primary key.
Virtualized Table
Virtualization can be used for scenes that need to render large-scale data. You can enable this feature by configuring the
virtualized
parameter. have to be aware of is:- Must pass
scroll.y
(number) andstyle.width
(number); - Need to pass the height of each line
virtualized.itemSize
(when not transmitting, the normal line height defaults to56
, and the group head line height defaults to56
), can be of the following types:number
(index, { sectionRow?: boolean, expandedRow?: boolean }) => number
- Table grouping virtualization requires version >=
0.37.0
.
The following is an example of rendering 1000 pieces of data.
Infinite Scroll
Based on the virtualization feature, we can achieve infinite scroll loading data by passing in
virtualized.onScroll
.Controlled Dynamic Tables
Fully custom rendering
Version: >=0.34.0
Generally, you can use
Column.render
, but you can also passColumn.useFullRender = true
to enable full custom rendering mode. At this time, the components such as checkbox button, expand button, indent will be Pass through to the Column.title
andColumn.render
methods, you can further define the rendering method of the header and cell content.The input parameters accepted by
Column.title
are:Column.render
The fourth input parameter is:The example below renders the checkbox and content into the same cell and header.
Header Merge
Version: >=1.1.0
Users can use the header merge function to group the header. The header merge can be combined with fixed column, virtualization, data grouping, column scaling and other functions. It also supports JSX or configurable writing.
Combined Header Configuration Writing
Merge Header JSX Writing
colSpan and rowSpan
- In addition to merging the headers by writing children, you can merge the headers by setting column.colSpan.
- Table supports row/column merging. When the cell attribute colSpan or rowSpan in render is set to 0, the set table will not be rendered.

Accessibility
ARIA
- The role of the table is grid, and the role of the tree table is treegrid
- the row's role is row, and the cell's role is gridcell
- Added aria-rowcount and aria-colcount attributes to the table to indicate the number of rows and columns
- The row has added aria-rowindex to indicate which row it currently belongs to, and the first row is 1
- The row of the tree table has aria-level representing the tree level of the current row, the first level is 1
- Expandable table rows have the aria-expanded attribute, indicating whether the current row is expanded
- The new aria-colindex of the cell indicates which column the current grid belongs to, and the first column is 1
- Added aria-label to column filter and sort buttons, and added aria-label attribute to row select buttons
Content Guidelines
- Table title
- The title of the table should clearly make the user perceive the purpose of the table;
- Add descriptions to complex tables to provide users with more contextual information about the table;
- use sentence case;
- Column headers
- Keep column headings concise, it is recommended to use 1-2 words as column headings;
- When the column header is long, it is recommended to display it in 2 lines, and the remaining text is abbreviated and displayed completely in the Tooltip;
- Adopt the capitalization rules of Sentence case;
- Use sentence case for column headings;
- Table operation area
- You can follow Button's content Guidelines

FAQ
- Why is the table data not updated?
At present, all parameters of the table component are shallow comparison. That is to say, if the parameter value type is an array or object, you need to manually change its reference to trigger the update. Similarly, if you don't want to trigger additional updates, try not to use literal values when passing parameters directly or define reference parameter values in the render process:The above writing method will trigger the update of data in the table every time render (the current selected row will be cleared and the row key array will be expanded, etc.). In order to improve performance and avoid some exceptions, please define some reference type parameters outside the render method as far as possible (if hooks are used, please use useMemo or useState for storage).** - Why can't my form line be selected and expanded?Please specify a rowKey or set a different "key" attribute for each item of the dataSource. All rows related operations in the table need to be used.
- How to implement custom sorting or pass parameters to the server for sorting when clicking the sort button?The input parameters of the onChange method include pagination, filters, and sorter. Users can customize the sorting of the dataSource according to the sorter.
- How to add className to a row?Use onRow or onHeaderRow.
- How to style the table cell?It can be controlled by column.onHeaderCell and column.onCell.
- Why cache the previously selected keys for the first parameter of
rowSelection
onChange
?This is for the scenario where the selected row keys are lost when data is selected on the first page during paging, and then the data is selected on the second page. If you don't want to use the cached keys, you can filter it from the current dataSource or use the second parameter ofrowSelection
onChange
. - Does it support single row selection?Table currently does not support single-row selection function, and users can implement single selection in a custom way. Please check the FAQ.
- How is Table implemented, I want to know more details?Please click Semi Table component design
