TanStack Table

Headless data tables with server-side pagination, filtering, sorting, and virtualization for Cloudflare Workers + D1

Quick Start

Last Updated: 2025-11-28 Versions: @tanstack/react-table@8.21.3, @tanstack/react-virtual@3.13.12

npm install @tanstack/react-table@latest
npm install @tanstack/react-virtual@latest  # For virtualization

Basic Setup (CRITICAL: memoize data/columns to prevent infinite re-renders):

import { useReactTable, getCoreRowModel, ColumnDef } from '@tanstack/react-table'
import { useMemo } from 'react'

const columns: ColumnDef<User>[] = [
  { accessorKey: 'name', header: 'Name' },
  { accessorKey: 'email', header: 'Email' },
]

function UsersTable() {
  const data = useMemo(() => [...users], []) // Stable reference
  const table = useReactTable({ data, columns, getCoreRowModel: getCoreRowModel() })

  return (
    <table>
      <thead>
        {table.getHeaderGroups().map(group => (
          <tr key={group.id}>
            {group.headers.map(h => <th key={h.id}>{h.column.columnDef.header}</th>)}
          </tr>
        ))}
      </thead>
      <tbody>
        {table.getRowModel().rows.map(row => (
          <tr key={row.id}>
            {row.getVisibleCells().map(cell => <td key={cell.id}>{cell.renderValue()}</td>)}
          </tr>
        ))}
      </tbody>
    </table>
  )
}

Server-Side Patterns

Cloudflare D1 API (pagination + filtering + sorting):

// Workers API: functions/api/users.ts
export async function onRequestGet({ request, env }) {
  const url = new URL(request.url)
  const page = Number(url.searchParams.get('page')) || 0
  const pageSize = 20
  const search = url.searchParams.get('search') || ''
  const sortBy = url.searchParams.get('sortBy') || 'created_at'
  const sortOrder = url.searchParams.get('sortOrder') || 'DESC'

  const { results } = await env.DB.prepare(`
    SELECT * FROM users
    WHERE name LIKE ? OR email LIKE ?
    ORDER BY ${sortBy} ${sortOrder}
    LIMIT ? OFFSET ?
  `).bind(`%${search}%`, `%${search}%`, pageSize, page * pageSize).all()

  const { total } = await env.DB.prepare('SELECT COUNT(*) as total FROM users').first()

  return Response.json({
    data: results,
    pagination: { page, pageSize, total, pageCount: Math.ceil(total / pageSize) },
  })
}

Client-Side (TanStack Query + Table):

const [pagination, setPagination] = useState({ pageIndex: 0, pageSize: 20 })
const [columnFilters, setColumnFilters] = useState([])
const [sorting, setSorting] = useState([])

// CRITICAL: Include ALL state in query key
const { data, isLoading } = useQuery({
  queryKey: ['users', pagination, columnFilters, sorting],
  queryFn: async () => {
    const params = new URLSearchParams({
      page: pagination.pageIndex,
      search: columnFilters.find(f => f.id === 'search')?.value || '',
      sortBy: sorting[0]?.id || 'created_at',
      sortOrder: sorting[0]?.desc ? 'DESC' : 'ASC',
    })
    return fetch(`/api/users?${params}`).then(r => r.json())
  },
})

const table = useReactTable({
  data: data?.data ?? [],
  columns,
  getCoreRowModel: getCoreRowModel(),
  // CRITICAL: manual* flags tell table server handles these
  manualPagination: true,
  manualFiltering: true,
  manualSorting: true,
  pageCount: data?.pagination.pageCount ?? 0,
  state: { pagination, columnFilters, sorting },
  onPaginationChange: setPagination,
  onColumnFiltersChange: setColumnFilters,
  onSortingChange: setSorting,
})

Virtualization (1000+ Rows)

Render only visible rows for performance:

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

function VirtualizedTable() {
  const containerRef = useRef<HTMLDivElement>(null)
  const table = useReactTable({ data: largeDataset, columns, getCoreRowModel: getCoreRowModel() })
  const { rows } = table.getRowModel()

  const rowVirtualizer = useVirtualizer({
    count: rows.length,
    getScrollElement: () => containerRef.current,
    estimateSize: () => 50, // Row height px
    overscan: 10,
  })

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

Known Issues & Solutions

Issue #1: Infinite Re-Renders

• Error: Table re-renders infinitely, browser freezes
• Cause: data or columns references change on every render
• Fix: Use useMemo(() => [...], []) or define data/columns outside component

Issue #2: Query + Table State Mismatch

• Error: Query refetches but pagination state not synced, stale data
• Cause: Query key missing table state (pagination, filters, sorting)
• Fix: Include ALL state in query key: queryKey: ['users', pagination, columnFilters, sorting]

Issue #3: Server-Side Features Not Working

• Error: Pagination/filtering/sorting doesn't trigger API calls
• Cause: Missing manual* flags
• Fix: Set manualPagination: true, manualFiltering: true, manualSorting: true + provide pageCount

Issue #4: TypeScript "Cannot Find Module"

• Error: Import errors for createColumnHelper
• Fix: Import from @tanstack/react-table (NOT @tanstack/table-core)

Issue #5: Sorting Not Working Server-Side

• Error: Clicking sort headers doesn't update data
• Cause: Sorting state not in query key/API params
• Fix: Include sorting in query key, add sort params to API call, set manualSorting: true + onSortingChange

Issue #6: Poor Performance (1000+ Rows)

• Error: Table slow/laggy with large datasets
• Fix: Use TanStack Virtual for client-side OR implement server-side pagination
