§@gravity-ui/table ·

§安装

npm install --save @gravity-ui/table

§用法

import React from 'react';
import {Table, useTable} from '@gravity-ui/table';
import type {ColumnDef} from '@gravity-ui/table/tanstack';

interface Person {
  id: string;
  name: string;
  age: number;
}

const columns: ColumnDef<Person>[] = [
  {accessorKey: 'name', header: 'Name', size: 100},
  {accessorKey: 'age', header: 'Age', size: 100},
];

const data: Person[] = [
  {id: 'name', name: 'John', age: 23},
  {id: 'age', name: 'Michael', age: 27},
];

const BasicExample = () => {
  const table = useTable({
    columns,
    data,
  });

  return <Table table={table} />;
};

§组件

您可以使用两个 Table 组件：

• BaseTable - 仅包含基本样式的组件；
• Table - 包含基于 Gravity UI 的样式的组件。

§行选择

import {selectionColumn} from '@gravity-ui/table';
import type {RowSelectionState} from '@gravity-ui/table/tanstack';

const columns: ColumnDef<Person>[] = [
  selectionColumn as ColumnDef<Person>,
  // ...其他列
];

const data: Person[] = [
  /* ... */
];

const RowSelectionExample = () => {
  const [rowSelection, setRowSelection] = React.useState<RowSelectionState>({});

  const table = useTable({
    columns,
    data,
    enableRowSelection: true,
    enableMultiRowSelection: true,
    onRowSelectionChange: setRowSelection,
    state: {
      rowSelection,
    },
  });

  return <Table table={table} />;
};

要将分组与选择结合使用，请使用 useRowSelectionFixedHandler hook。没有它，父行复选框的状态将不正确。https://github.com/TanStack/table/issues/4878

§自定义范围选择列

useToggleRangeSelectionHandler hook 返回一个更改处理程序，该处理程序监听 Shift+click 事件并执行范围行选择。它需要一个 CellContext 实例才能访问表格和行的内部状态。

import React, {type ChangeEvent, useCallback, useState} from 'react';

import {Table, useToggleRangeSelectionHandler, useTable} from '@gravity-ui/table';
import type {CellContext, ColumnDef, RowSelectionState} from '@gravity-ui/table/tanstack';
import {Checkbox, type CheckboxProps} from '@gravity-ui/uikit';

type CustomRangedSelectionCheckboxProps = Omit<CheckboxProps, 'onChange'> & {
  cellContext: CellContext<unknown, unknown>;
};

const CustomRangedSelectionCheckbox = ({
  className,
  cellContext,
  ...restProps
}: CustomRangedSelectionCheckboxProps) => {
  const rowToggleRangedSelectionHandler = useToggleRangeSelectionHandler(cellContext);

  const handleChange = useCallback(
    (event: ChangeEvent<HTMLInputElement>): void => {
      rowToggleRangedSelectionHandler(event);
    },
    [rowToggleRangedSelectionHandler],
  );

  return <Checkbox {...restProps} onChange={handleChange} />;
};

const customSelectionColumn: ColumnDef<unknown> = {
  id: '_select',
  header: ({table}) => (
    <Checkbox
      size="l"
      checked={table.getIsAllRowsSelected()}
      indeterminate={table.getIsSomeRowsSelected()}
      onChange={table.getToggleAllRowsSelectedHandler()}
    />
  ),
  cell: (cellContext) => (
    <CustomRangedSelectionCheckbox
      size="l"
      checked={cellContext.row.getIsSelected()}
      disabled={!cellContext.row.getCanSelect()}
      indeterminate={cellContext.row.getIsSomeSelected()}
      cellContext={cellContext}
    />
  ),
  size: 41,
  maxSize: 41,
  minSize: 41,
  enableResizing: false,
  enableSorting: false,
};

const columns: ColumnDef<Person>[] = [
  customSelectionColumn as ColumnDef<Person>,
  // ...其他列
];

const data: Person[] = [
  /* ... */
];

const RowRangedSelectionExample = () => {
  const [rowSelection, setRowSelection] = useState<RowSelectionState>({});

  const table = useTable({
    columns,
    data,
    enableRowSelection: true,
    enableMultiRowSelection: true,
    onRowSelectionChange: setRowSelection,
    state: {
      rowSelection,
    },
  });

  return <Table table={table} />;
};

还有一个 RangedSelectionCheckbox 组件，它在内部使用 hook 并接受 CellContext 实例作为 prop。此组件为向自定义选择列添加范围选择功能提供了快捷方式。

import type {ColumnDef} from '@gravity-ui/table/tanstack';
import {RangedSelectionCheckbox, SelectionCheckbox} from '@gravity-ui/table';

export const selectionColumn: ColumnDef<unknown> = {
  id: '_select',
  header: ({table}) => (
    <SelectionCheckbox
      checked={table.getIsAllRowsSelected()}
      disabled={!table.options.enableRowSelection}
      indeterminate={table.getIsSomeRowsSelected()}
      onChange={table.getToggleAllRowsSelectedHandler()}
    />
  ),
  cell: (cellContext) => (
    <RangedSelectionCheckbox
      checked={cellContext.row.getIsSelected()}
      disabled={!cellContext.row.getCanSelect()}
      indeterminate={cellContext.row.getIsSomeSelected()}
      cellContext={cellContext}
    />
  ),
  meta: {
    hideInSettings: true,
  },
  size: 32,
  minSize: 32,
};

默认情况下，使用 selectionColumn 生成的选择列包含范围选择功能。

import {selectionColumn} from '@gravity-ui/table';
import type {ColumnDef} from '@gravity-ui/table/tanstack';

const columns: ColumnDef<Person>[] = [
  selectionColumn as ColumnDef<Person>,
  // ...其他列
];

注意: 如果表格包含嵌套行，则范围选择将不起作用。目前，这被认为是未定义行为。

§排序

了解 react-table 的列属性，请参阅 文档。

import type {SortingState} from '@gravity-ui/table/tanstack';

const columns: ColumnDef<Person>[] = [
  /* ... */
];

const data: Person[] = [
  /* ... */
];

const SortingExample = () => {
  const [sorting, setSorting] = React.useState<SortingState>([]);

  // 要启用排序，您的列必须具有 accessorFn

  const table = useTable({
    columns,
    data,
    enableSorting: true,
    getRowId: (item) => item.id,
    onSortingChange: setSorting,
    state: {
      sorting,
    },
  });

  return <Table table={table} />;
};

如果您想手动排序元素，请传递 manualSorting 属性：

const table = useTable({
  // ...
  manualSorting: true,
});

§分组

import type {ExpandedState, Row} from '@gravity-ui/table/tanstack';

interface Person {
  id: string;
  name: string;
  age: number;
}

interface PersonGroup {
  id: string;
  name: string;
  items: Person[];
}

type Item = PersonGroup | Person;

const columns: ColumnDef<Item>[] = [
  {accessorKey: 'name', header: 'Name', size: 200},
  {accessorKey: 'age', header: 'Age', size: 100},
];

const data: Item[] = [
  {
    id: 'friends',
    name: 'Friends',
    items: [
      {id: 'nick', name: 'Nick', age: 25},
      {id: 'tom', name: 'Tom', age: 21},
    ],
  },
  {
    id: 'relatives',
    name: 'Relatives',
    items: [
      {id: 'john', name: 'John', age: 23},
      {id: 'michael', name: 'Michael', age: 27},
    ],
  },
];

const getGroupTitle = (row: Row<Item>) => row.getValue<string>('name');

const GroupingExample = () => {
  const [expanded, setExpanded] = React.useState<ExpandedState>({});

  const table = useTable({
    columns,
    data,
    enableExpanding: true,
    getSubRows: (item) => ('items' in item ? item.items : undefined),
    onExpandedChange: setExpanded,
    state: {
      expanded,
    },
  });

  return <Table table={table} getGroupTitle={getGroupTitle} />;
};

要将分组与选择结合使用，请使用 useRowSelectionFixedHandler hook。否则，父行复选框的状态将不正确。https://github.com/TanStack/table/issues/4878

要启用嵌套样式，请在列配置中传递 withNestingStyles = true。

可以通过传递 showTreeDepthIndicators = false 来禁用嵌套指示器。

要添加用于展开/折叠行的控件，请将单元格内容包装在 TreeExpandableCell 组件或您类似的自定义组件中：

import {TreeExpandableCell} from '@gravity-ui/table';

const columns: ColumnDef<Item>[] = [
  {
    accessorKey: 'name',
    header: 'Name',
    size: 200,
    showTreeDepthIndicators: false,
    withNestingStyles: true,
    cell: ({row, info}) => (
      <TreeExpandableCell row={row}>{info.getValue<string>()}</TreeExpandableCell>
    ),
  },
  // ...其他列
];

§重排

import type {ReorderingProviderProps} from '@gravity-ui/table';
import {dragHandleColumn, ReorderingProvider} from '@gravity-ui/table';

const columns: ColumnDef<Person>[] = [
  dragHandleColumn,
  // ...其他列
];

const data: Person[] = [
  /* ... */
];

const ReorderingExample = () => {
  const table = useTable({
    columns,
    data,
    getRowId: (item) => item.id,
  });

  const handleReorder = React.useCallback<
    NonNullable<ReorderingProviderProps<Person>['onReorder']>
  >(
    ({
      draggedItemKey,
      targetItemKey,
      baseItemKey,
      baseNextItemKey,
      enableNesting,
      nextChild,
      pullFromParent,
    }) => {
      // ...
    },
    [],
  );

  return (
    <ReorderingProvider table={table} onReorder={handleReorder}>
      <Table table={table} />
    </ReorderingProvider>
  );
};

§虚拟化

如果希望将网格容器用作滚动元素（如果您想使用窗口，请参阅窗口虚拟化部分），请使用此功能。请确保为容器设置固定的高度，否则虚拟化将不起作用。

import {useRowVirtualizer} from '@gravity-ui/table';

const columns: ColumnDef<Person>[] = [
  /* ... */
];

const data: Person[] = [
  /* ... */
];

const VirtualizationExample = () => {
  const table = useTable({
    columns,
    data,
    getRowId: (item) => item.id,
  });

  const containerRef = React.useRef<HTMLDivElement>(null);

  const rowVirtualizer = useRowVirtualizer({
    count: table.getRowModel().rows.length,
    estimateSize: () => 20,
    overscan: 5,
    getScrollElement: () => containerRef.current,
  });

  return (
    <div ref={containerRef} style={{height: '500px', overflow: 'auto'}}>
      <Table table={table} rowVirtualizer={rowVirtualizer} />
    </div>
  );
};

如果您将虚拟化与重排功能一起使用，还需要传递 rangeExtractor 选项：

import {getVirtualRowRangeExtractor} from '@gravity-ui/table';

// ...

const tableRef = React.useRef<HTMLTableElement>(null);

const rowVirtualizer = useRowVirtualizer({
  // ...
  rangeExtractor: getVirtualRowRangeExtractor(tableRef.current),
});

return (
  <TableWithReordering
    ref={tableRef}
    table={table}
    rowVirtualizer={rowVirtualizer}
    onReorder={handleReorder}
  />
);

§窗口虚拟化

如果您希望将窗口用作滚动元素，请使用此功能。

import {useWindowRowVirtualizer} from '@gravity-ui/table';

const columns: ColumnDef<Person>[] = [
  /* ... */
];

const data: Person[] = [
  /* ... */
];

const WindowVirtualizationExample = () => {
  const table = useTable({
    columns,
    data,
    getRowId: (item) => item.id,
  });

  const bodyRef = React.useRef<HTMLTableSectionElement>(null);

const rowVirtualizer = useWindowRowVirtualizer({
    count: table.getRowModel().rows.length,
    estimateSize: () => 20,
    overscan: 5,
    scrollMargin: bodyRef.current?.offsetTop ?? 0,
  });

  return <Table table={table} rowVirtualizer={rowVirtualizer} bodyRef={bodyRef} />;
};

§列宽调整

const columns: ColumnDef<Person>[] = [
  /* ... */
];

const data: Person[] = [
  /* ... */
];

const ResizingDemo = () => {
  const table = useTable({
    columns,
    data,
    enableColumnResizing: true,
    columnResizeMode: 'onChange',
  });

  return <Table table={table} />;
};

§列设置

const columns: ColumnDef<Person>[] = [
  // ...other columns
  {
    id: 'settings_column_id',
    header: ({table}) => <TableSettings table={table} />,
    meta: {
      hideInSettings: false, // 可选。允许在设置弹出窗口中隐藏此列
      titleInSettings: 'ReactNode', // 可选。覆盖设置弹出窗口的 header 字段（如果您需要与 header 不同的内容用于设置弹出窗口）
    },
  }, // 或者您可以使用 getSettingsColumn 函数
];

const data: Person[] = [
  /* ... */
];

const TableSettingsDemo = () => {
  const [columnVisibility, onColumnVisibilityChange] = React.useState<VisibilityState>({
    // 用于外部控制和初始状态
    column_id: false, // 用于默认隐藏
  });
  const [columnOrder, onColumnOrderChange] = React.useState<string[]>([
    /* leaf columns ids */
  ]); // 用于外部控制和初始状态

  // 使用 useTableSettings hook 获取状态、回调和在设置应用时设置回调的替代方案：
  // const {state, callbacks} = useTableSettings({initialVisibility: {}, initialOrder: []})

  const table = useTable({
    columns,
    data,
    state: {
      columnVisibility,
      columnOrder,
    },
    onColumnVisibilityChange,
    onColumnOrderChange,
  });

  return <Table table={table} />;
};
