Basic Client-Side Table

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

interface User {
  id: string
  name: string
  email: string
}

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

function UsersTable() {
  // CRITICAL: Memoize data and columns to prevent infinite re-renders
  const data = useMemo<User[]>(() => [
    { id: '1', name: 'Alice', email: 'alice@example.com' },
    { id: '2', name: 'Bob', email: 'bob@example.com' },
  ], [])

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

  return (
    <table>
      <thead>
        {table.getHeaderGroups().map(headerGroup => (
          <tr key={headerGroup.id}>
            {headerGroup.headers.map(header => (
              <th key={header.id}>
                {header.isPlaceholder ? null : header.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 (Recommended for Large Datasets)

Pattern 1: Server-Side Pagination with TanStack Query

Cloudflare Workers API Endpoint:

// src/routes/api/users.ts
import { Env } from '../../types'

export async function onRequestGet(context: { request: Request; env: Env }) {
  const url = new URL(context.request.url)
  const page = Number(url.searchParams.get('page')) || 0
  const pageSize = Number(url.searchParams.get('pageSize')) || 20

  const offset = page * pageSize

  // Query D1 database
  const { results, meta } = await context.env.DB.prepare(`
    SELECT id, name, email, created_at
    FROM users
    ORDER BY created_at DESC
    LIMIT ? OFFSET ?
  `).bind(pageSize, offset).all()

  // Get total count for pagination
  const countResult = await context.env.DB.prepare(`
    SELECT COUNT(*) as total FROM users
  `).first<{ total: number }>()

  return Response.json({
    data: results,
    pagination: {
      page,
      pageSize,
      total: countResult?.total || 0,
      pageCount: Math.ceil((countResult?.total || 0) / pageSize),
    },
  })
}

Client-Side Table with TanStack Query:

import { useReactTable, getCoreRowModel, PaginationState } from '@tanstack/react-table'
import { useQuery } from '@tanstack/react-query'
import { useState } from 'react'

function ServerPaginatedTable() {
  const [pagination, setPagination] = useState<PaginationState>({
    pageIndex: 0,
    pageSize: 20,
  })

  // TanStack Query fetches data
  const { data, isLoading } = useQuery({
    queryKey: ['users', pagination.pageIndex, pagination.pageSize],
    queryFn: async () => {
      const response = await fetch(
        `/api/users?page=${pagination.pageIndex}&pageSize=${pagination.pageSize}`
      )
      return response.json()
    },
  })

  // TanStack Table manages display
  const table = useReactTable({
    data: data?.data ?? [],
    columns,
    getCoreRowModel: getCoreRowModel(),
    // Server-side pagination config
    manualPagination: true, // CRITICAL: Tell table pagination is manual
    pageCount: data?.pagination.pageCount ?? 0,
    state: { pagination },
    onPaginationChange: setPagination,
  })

  if (isLoading) return <div>Loading...</div>

  return (
    <div>
      <table>{/* render table */}</table>

      {/* Pagination controls */}
      <div>
        <button
          onClick={() => table.previousPage()}
          disabled={!table.getCanPreviousPage()}
        >
          Previous
        </button>
        <span>
          Page {table.getState().pagination.pageIndex + 1} of{' '}
          {table.getPageCount()}
        </span>
        <button
          onClick={() => table.nextPage()}
          disabled={!table.getCanNextPage()}
        >
          Next
        </button>
      </div>
    </div>
  )
}

Pattern 2: Server-Side Filtering

API with Filter Support:

export async function onRequestGet(context: { request: Request; env: Env }) {
  const url = new URL(context.request.url)
  const search = url.searchParams.get('search') || ''

  const { results } = await context.env.DB.prepare(`
    SELECT * FROM users
    WHERE name LIKE ? OR email LIKE ?
    LIMIT 20
  `).bind(`%${search}%`, `%${search}%`).all()

  return Response.json({ data: results })
}

Client-Side:

const [columnFilters, setColumnFilters] = useState<ColumnFiltersState>([])

const { data } = useQuery({
  queryKey: ['users', columnFilters],
  queryFn: async () => {
    const search = columnFilters.find(f => f.id === 'search')?.value || ''
    return fetch(`/api/users?search=${search}`).then(r => r.json())
  },
})

const table = useReactTable({
  data: data?.data ?? [],
  columns,
  getCoreRowModel: getCoreRowModel(),
  manualFiltering: true, // CRITICAL: Server handles filtering
  state: { columnFilters },
  onColumnFiltersChange: setColumnFilters,
})

Virtualization for Large Datasets

For 1000+ rows, use TanStack Virtual to only render visible rows:

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

function VirtualizedTable() {
  const tableContainerRef = useRef<HTMLDivElement>(null)

  const table = useReactTable({
    data: largeDataset, // 10k+ rows
    columns,
    getCoreRowModel: getCoreRowModel(),
  })

  const { rows } = table.getRowModel()

  // Virtualize rows
  const rowVirtualizer = useVirtualizer({
    count: rows.length,
    getScrollElement: () => tableContainerRef.current,
    estimateSize: () => 50, // Row height in px
    overscan: 10, // Render 10 extra rows for smooth scrolling
  })

  return (
    <div ref={tableContainerRef} style={{ height: '600px', overflow: 'auto' }}>
      <table style={{ height: `${rowVirtualizer.getTotalSize()}px` }}>
        <thead>{/* header */}</thead>
        <tbody>
          {rowVirtualizer.getVirtualItems().map(virtualRow => {
            const row = rows[virtualRow.index]
            return (
              <tr
                key={row.id}
                style={{
                  position: 'absolute',
                  transform: `translateY(${virtualRow.start}px)`,
                  width: '100%',
                }}
              >
                {row.getVisibleCells().map(cell => (
                  <td key={cell.id}>{cell.renderValue()}</td>
                ))}
              </tr>
            )
          })}
        </tbody>
      </table>
    </div>
  )
}

Common Errors & Solutions

Error 1: Infinite Re-Renders

Problem: Table re-renders infinitely, browser freezes.

Cause: data or columns references change on every render.

Solution: Always use useMemo or useState:

// ❌ BAD: New array reference every render
function Table() {
  const data = [{ id: 1 }] // Creates new array!
  const table = useReactTable({ data, columns, getCoreRowModel: getCoreRowModel() })
}

// ✅ GOOD: Stable reference
function Table() {
  const data = useMemo(() => [{ id: 1 }], []) // Stable
  const table = useReactTable({ data, columns, getCoreRowModel: getCoreRowModel() })
}

// ✅ ALSO GOOD: Define outside component
const data = [{ id: 1 }]
function Table() {
  const table = useReactTable({ data, columns, getCoreRowModel: getCoreRowModel() })
}

Error 2: TanStack Query + Table State Mismatch

Problem: Query refetches but pagination state not in sync, causing stale data.

Solution: Include ALL table state in query key:

// ❌ BAD: Missing pagination in query key
const { data } = useQuery({
  queryKey: ['users'], // Doesn't include page!
  queryFn: () => fetch(`/api/users?page=${pagination.pageIndex}`).then(r => r.json())
})

// ✅ GOOD: Complete query key
const { data } = useQuery({
  queryKey: ['users', pagination.pageIndex, pagination.pageSize, columnFilters, sorting],
  queryFn: () => {
    const params = new URLSearchParams({
      page: pagination.pageIndex.toString(),
      pageSize: pagination.pageSize.toString(),
      // ... filters, sorting
    })
    return fetch(`/api/users?${params}`).then(r => r.json())
  }
})

Error 3: Server-Side Features Not Working

Problem: Pagination/filtering/sorting doesn't trigger API calls.

Solution: Set manual* flags to true:

const table = useReactTable({
  data,
  columns,
  getCoreRowModel: getCoreRowModel(),
  // CRITICAL: Tell table these are server-side
  manualPagination: true,
  manualFiltering: true,
  manualSorting: true,
  pageCount: serverPageCount, // Must provide total page count
})

Error 4: TypeScript "Cannot Find Module" for Column Helper

Problem: Import errors for createColumnHelper.

Solution: Import from correct path:

// ❌ BAD: Wrong path
import { createColumnHelper } from '@tanstack/table-core'

// ✅ GOOD: Correct path
import { createColumnHelper } from '@tanstack/react-table'

// Usage for type-safe columns
const columnHelper = createColumnHelper<User>()
const columns = [
  columnHelper.accessor('name', {
    header: 'Name',
    cell: info => info.getValue(), // Fully typed!
  }),
]

Error 5: Sorting Not Working with Server-Side

Problem: Clicking sort headers doesn't update data.

Solution: Include sorting in query key and API call:

const [sorting, setSorting] = useState<SortingState>([])

const { data } = useQuery({
  queryKey: ['users', pagination, sorting], // Include sorting
  queryFn: async () => {
    const sortParam = sorting[0]
      ? `&sortBy=${sorting[0].id}&sortOrder=${sorting[0].desc ? 'desc' : 'asc'}`
      : ''
    return fetch(`/api/users?page=${pagination.pageIndex}${sortParam}`).then(r => r.json())
  }
})

const table = useReactTable({
  data: data?.data ?? [],
  columns,
  getCoreRowModel: getCoreRowModel(),
  manualSorting: true,
  state: { sorting },
  onSortingChange: setSorting,
})

Error 6: Poor Performance with Large Datasets

Problem: Table slow/laggy with 1000+ rows.

Solution: Use virtualization (see example above) or implement server-side pagination.

Integration with Existing Skills

With tanstack-query Skill

TanStack Table + TanStack Query is the recommended pattern:

// Query handles data fetching + caching
const { data, isLoading } = useQuery({
  queryKey: ['users', tableState],
  queryFn: fetchUsers,
})

// Table handles display + interactions
const table = useReactTable({
  data: data?.data ?? [],
  columns,
  getCoreRowModel: getCoreRowModel(),
})

With cloudflare-d1 Skill

// Cloudflare Workers API (from cloudflare-d1 skill patterns)
export async function onRequestGet({ env }: { env: Env }) {
  const { results } = await env.DB.prepare('SELECT * FROM users LIMIT 20').all()
  return Response.json({ data: results })
}

// Client-side table consumes D1 data
const { data } = useQuery({
  queryKey: ['users'],
  queryFn: () => fetch('/api/users').then(r => r.json())
})

With tailwind-v4-shadcn Skill

Use shadcn/ui Table components with TanStack Table logic:

import { Table, TableHeader, TableBody, TableRow, TableHead, TableCell } from '@/components/ui/table'

function StyledTable() {
  const table = useReactTable({ /* config */ })

  return (
    <Table>
      <TableHeader>
        {table.getHeaderGroups().map(headerGroup => (
          <TableRow key={headerGroup.id}>
            {headerGroup.headers.map(header => (
              <TableHead key={header.id}>
                {header.column.columnDef.header}
              </TableHead>
            ))}
          </TableRow>
        ))}
      </TableHeader>
      <TableBody>
        {table.getRowModel().rows.map(row => (
          <TableRow key={row.id}>
            {row.getVisibleCells().map(cell => (
              <TableCell key={cell.id}>
                {cell.renderValue()}
              </TableCell>
            ))}
          </TableRow>
        ))}
      </TableBody>
    </Table>
  )
}

Best Practices

1. Always Memoize Data and Columns

const data = useMemo(() => [...], [dependencies])
const columns = useMemo(() => [...], [])

2. Use Server-Side for Large Datasets

Client-side: <1000 rows
Server-side: 1000+ rows or frequently changing data

3. Coordinate Query Keys with Table State

queryKey: ['resource', pagination, filters, sorting]

4. Provide Loading States

if (isLoading) return <TableSkeleton />
if (error) return <ErrorMessage error={error} />

5. Use Column Helper for Type Safety

const columnHelper = createColumnHelper<YourType>()
const columns = [
  columnHelper.accessor('field', { /* fully typed */ })
]

6. Virtualize Large Client-Side Tables

if (data.length > 1000) {
  // Use TanStack Virtual (see example above)
}
