name	tanstack-table
description	Headless UI for building powerful tables & datagrids for TS/JS, React, Vue, Solid, Svelte, Qwik, Angular, and Lit.

Overview

TanStack Table is a headless UI library for building data tables and datagrids. It provides logic for sorting, filtering, pagination, grouping, expanding, column pinning/ordering/visibility/resizing, and row selection - without rendering any markup or styles.

Package: @tanstack/react-table Utilities: @tanstack/match-sorter-utils (fuzzy filtering) Current Version: v8

Installation

npm install @tanstack/react-table

Core Architecture

Building Blocks

1. Column Definitions - describe columns (data access, rendering, features)
2. Table Instance - central coordinator with state and APIs
3. Row Models - data processing pipeline (filter -> sort -> group -> paginate)
4. Headers, Rows, Cells - renderable units

Critical: Data & Column Stability

// WRONG - new references every render, causes infinite loops
const table = useReactTable({
  data: fetchedData.results,     // new ref!
  columns: [{ accessorKey: 'name' }], // new ref!
})

// CORRECT - stable references
const columns = useMemo(() => [...], [])
const data = useMemo(() => fetchedData?.results ?? [], [fetchedData])

const table = useReactTable({ data, columns, getCoreRowModel: getCoreRowModel() })

Column Definitions

Using createColumnHelper (Recommended)

import { createColumnHelper } from '@tanstack/react-table'

type Person = {
  firstName: string
  lastName: string
  age: number
  status: 'active' | 'inactive'
}

const columnHelper = createColumnHelper<Person>()

const columns = [
  // Accessor column (data column)
  columnHelper.accessor('firstName', {
    header: 'First Name',
    cell: info => info.getValue(),
    footer: info => info.column.id,
  }),

  // Accessor with function
  columnHelper.accessor(row => row.lastName, {
    id: 'lastName', // required with accessorFn
    header: () => <span>Last Name</span>,
    cell: info => <i>{info.getValue()}</i>,
  }),

  // Display column (no data, custom rendering)
  columnHelper.display({
    id: 'actions',
    header: 'Actions',
    cell: ({ row }) => (
      <button onClick={() => deleteRow(row.original)}>Delete</button>
    ),
  }),

  // Group column (nested headers)
  columnHelper.group({
    id: 'info',
    header: 'Info',
    columns: [
      columnHelper.accessor('age', { header: 'Age' }),
      columnHelper.accessor('status', { header: 'Status' }),
    ],
  }),
]

  getSortedRowModel,
  getFilteredRowModel,
  getPaginationRowModel,
  flexRender,
} from '@tanstack/react-table'

function MyTable() {
  const [sorting, setSorting] = useState<SortingState>([])
  const [columnFilters, setColumnFilters] = useState<ColumnFiltersState>([])
  const [pagination, setPagination] = useState<PaginationState>({
    pageIndex: 0,
    pageSize: 10,
  })

  const table = useReactTable({
    data,
    columns,
    state: { sorting, columnFilters, pagination },
    onSortingChange: setSorting,

    getFilteredRowModel: getFilteredRowModel(),
    getPaginationRowModel: getPaginationRowModel(),
  })

  return (
    <table>
      <thead>
        {table.getHeaderGroups().map(headerGroup => (
          <tr key={headerGroup.id}>
            {headerGroup.headers.map(header => (
              <th key={header.id} onClick={header.column.getToggleSortingHandler()}>
                {header.isPlaceholder ? null :
                  flexRender(header.column.columnDef.header, header.getContext())}
                {{ asc: ' ↑', desc: ' ↓' }[header.column.getIsSorted() as string] ?? null}
              </th>
            ))}
          </tr>
        ))}
      </thead>
      <tbody>
        {table.getRowModel().rows.map(row => (

{row.getIsExpanded() && (
  <tr>
    <td colSpan={columns.length}>
      <DetailComponent data={row.original} />
    </td>
  </tr>
)}

Virtualization Integration

import { useVirtualizer } from '@tanstack/react-virtual'

function VirtualizedTable() {
  const table = useReactTable({ /* ... */ })
  const { rows } = table.getRowModel()
  const parentRef = useRef<HTMLDivElement>(null)

  const virtualizer = useVirtualizer({
    count: rows.length,
    getScrollElement: () => parentRef.current,
    estimateSize: () => 35,
    overscan: 10,
  })

  return (
    <div ref={parentRef} style={{ height: '600px', overflow: 'auto' }}>
      <table>
        <tbody style={{ height: `${virtualizer.getTotalSize()}px`, position: 'relative' }}>
          {virtualizer.getVirtualItems().map(virtualRow => {
            const row = rows[virtualRow.index]
            return (
              <tr
                key={row.id}
                style={{
                  position: 'absolute',
                  transform: `translateY(${virtualRow.start}px)`,
                  height: `${virtualRow.size}px`,
                }}
              >
                {row.getVisibleCells().map(cell => (
                  <td key={cell.id}>
                    {flexRender(cell.column.columnDef.cell, cell.getContext())}
                  </td>
                ))}
              </tr>
            )
          })}
        </tbody>
      </table>
    </div>
  )
}

Server-Side Operations

const table = useReactTable({
  data: serverData,
  columns,
  manualSorting: true,
  manualFiltering: true,
  manualPagination: true,
  pageCount: serverPageCount,
  state: { sorting, columnFilters, pagination },
  onSortingChange: setSorting,
  onColumnFiltersChange: setColumnFilters,
  onPaginationChange: setPagination,
  getCoreRowModel: getCoreRowModel(),
  // Do NOT include getSortedRowModel, getFilteredRowModel, getPaginationRowModel
});

// Fetch data based on state
useEffect(() => {
  fetchData({ sorting, filters: columnFilters, pagination });
}, [sorting, columnFilters, pagination]);

TypeScript Patterns

Extending Column Meta

declare module "@tanstack/react-table" {
  interface ColumnMeta<TData extends RowData, TValue> {
    filterVariant?: "text" | "range" | "select";
    align?: "left" | "center" | "right";
  }
}

Custom Filter/Sort Function Registration

declare module "@tanstack/react-table" {
  interface FilterFns {
    fuzzy: FilterFn<unknown>;
  }
  interface SortingFns {
    myCustomSort: SortingFn<unknown>;
  }
}

Editable Cells via Table Meta

declare module "@tanstack/react-table" {
  interface TableMeta<TData extends RowData> {
    updateData: (rowIndex: number, columnId: string, value: unknown) => void;
  }
}

const table = useReactTable({
  meta: {
    updateData: (rowIndex, columnId, value) => {
      setData((old) => old.map((row, i) => (i === rowIndex ? { ...row, [columnId]: value } : row)));
    },
  },
});

Key Imports

import {
  createColumnHelper,
  flexRender,
  useReactTable,
  getCoreRowModel,
  getSortedRowModel,
  getFilteredRowModel,
  getPaginationRowModel,
  getGroupedRowModel,
  getExpandedRowModel,
  getFacetedRowModel,
  getFacetedUniqueValues,
  getFacetedMinMaxValues,
} from "@tanstack/react-table";

import type {
  ColumnDef,
  SortingState,
  ColumnFiltersState,
  VisibilityState,
  PaginationState,
  ExpandedState,
  RowSelectionState,
  GroupingState,
  ColumnOrderState,
  ColumnPinningState,
  FilterFn,
  SortingFn,
} from "@tanstack/react-table";

Best Practices

1. Always memoize data and columns to prevent infinite re-renders
2. Use flexRender for all header/cell/footer rendering
3. Use table.getRowModel().rows for final rendered rows (not getCoreRowModel)
4. Import only needed row models - each adds processing to the pipeline
5. Use getRowId for stable row keys when data has unique IDs
6. Use manualX options for server-side operations
7. Pair controlled state with both state.X and onXChange
8. Use module augmentation for custom meta, filter fns, sort fns
9. Use column helper for type-safe column definitions
10. Set autoResetPageIndex: true when filtering should reset pagination

Common Pitfalls

• Defining columns inline (creates new ref each render)
• Forgetting getCoreRowModel() (required for all tables)
• Using row models without importing them
• Not providing id when using accessorFn
• Mixing manualPagination with client-side getPaginationRowModel
• Forgetting colSpan for grouped headers
• Not handling header.isPlaceholder for group column spacers
