Install

npm install --save @gravity-ui/table

Usage

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} />;
};

Components

There are two Table components that you can use:

• BaseTable - a component with basic styles only;
• Table - a component with Gravity UI based styles.

Row selection

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

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

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} />;
};

Sorting

Learn about the column properties in the react-table docs

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

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

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

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

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

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

If you want to sort the elements manually pass manualSorting property:

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

Grouping

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} />;
};

Reordering

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

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

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>
  );
};

Virtualization

Use if you want to use grid container as the scroll element (if you want to use window see window virtualization section).

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>
  );
};

If you use virtualization with reordering feature you also need to pass rangeExtractor option:

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}
  />
);

Window virtualization

Use if you want to use window as the scroll element

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} />;
};

Resizing

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

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

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

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

Column settings

const columns: ColumnDef<Person>[] = [
  // ...other columns
  {
    id: 'settings_column_id',
    header: ({table}) => <TableSettings table={table} />,
    meta: {
      hideInSettings: false, // Optional. Allows to hide this column from settings popover
      titleInSettings: 'ReactNode', // Optional. Overrides header field for settings popover (if you need different content for header and settings popover)
    },
  }, // or you can use function getSettingsColumn
];

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

const TableSettingsDemo = () => {
  const [columnVisibility, onColumnVisibilityChange] = React.useState<VisibilityState>({
    // for outside control and initial state
    column_id: false, // for hidding by default
  });
  const [columnOrder, onColumnOrderChange] = React.useState<string[]>([
    /* leaf columns ids */
  ]); // for outside control and initial state

  // Alternative variant to get state, callbacks, and set on setting apply callbacks - using useTableSettings hook:
  // const {state, callbacks} = useTableSettings({initialVisibility: {}, initialOrder: []})

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

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