Material React Table Mastery

Build production-grade data tables w/ MRT V3 (TanStack Table V8 + MUI).

When to Use

• Building data tables with MUI styling
• Server-side pagination/filtering/sorting
• CRUD editing (inline, modal, cell, table)
• Large dataset virtualization (10k+ rows)
• Complex filtering (date range, multi-select, faceted)
• Migrating between MRT versions (V1→V2→V3)
• MUI v7 compatibility issues

Triggers

• /mrt-init - Initialize MRT setup w/ dependencies
• /mrt-column - Generate typed column definitions
• /mrt-crud - Add CRUD editing capabilities
• /mrt-server - Configure server-side pagination/filtering/sorting
• /mrt-migrate - Migrate between MRT versions (V1→V2→V3)
• /mrt-state - State management, persistence, controlled state
• /mrt-export - Data export (CSV, Excel, PDF)
• /mrt-a11y - Accessibility & keyboard navigation setup

Core Tenets

1. TanStack Table Foundation

MRT wraps TanStack Table V8. Use useMaterialReactTable hook for full control.

import { useMaterialReactTable, MaterialReactTable } from 'material-react-table';

const table = useMaterialReactTable({
  columns,
  data,
  enableColumnFilters: true,
  enableGlobalFilter: true,
  enablePagination: true,
});

return <MaterialReactTable table={table} />;

2. Column Definitions in useMemo

ALWAYS wrap columns in useMemo to prevent unnecessary re-renders.

const columns = useMemo<MRT_ColumnDef<Person>[]>(() => [
  { accessorKey: 'name', header: 'Name', size: 200 },
  {
    accessorFn: (row) => `${row.firstName} ${row.lastName}`,
    id: 'fullName',
    header: 'Full Name',
  },
  {
    accessorKey: 'status',
    header: 'Status',
    filterVariant: 'select',
    filterSelectOptions: ['Active', 'Inactive', 'Pending'],
    Cell: ({ cell }) => (
      <Chip
        label={cell.getValue<string>()}
        color={cell.getValue() === 'Active' ? 'success' : 'default'}
      />
    ),
  },
  {
    accessorKey: 'salary',
    header: 'Salary',
    filterVariant: 'range-slider',
    Cell: ({ cell }) => cell.getValue<number>().toLocaleString('en-US', {
      style: 'currency', currency: 'USD',
    }),
    aggregationFn: 'sum',
    AggregatedCell: ({ cell }) => `Total: ${cell.getValue()}`,
  },
], []);

3. Server-Side Operations

For datasets > 100 rows, use server-side pagination/filtering/sorting.

const [pagination, setPagination] = useState({ pageIndex: 0, pageSize: 10 });
const [sorting, setSorting] = useState<MRT_SortingState>([]);
const [globalFilter, setGlobalFilter] = useState('');

const { data, isLoading } = useQuery({
  queryKey: ['users', pagination, sorting, globalFilter],
  queryFn: () => fetchUsers({ pagination, sorting, globalFilter }),
});

const table = useMaterialReactTable({
  columns,
  data: data?.rows ?? [],
  rowCount: data?.totalCount ?? 0,
  manualPagination: true,
  manualSorting: true,
  manualFiltering: true,
  state: { pagination, sorting, globalFilter, isLoading },
  onPaginationChange: setPagination,
  onSortingChange: setSorting,
  onGlobalFilterChange: setGlobalFilter,
});

4. CRUD Editing

Support inline, modal, cell, or table editing modes.

const table = useMaterialReactTable({
  columns,
  data,
  enableEditing: true,
  editDisplayMode: 'row', // 'modal' | 'cell' | 'table'
  onEditingRowSave: async ({ values, row, table }) => {
    await updateUser(row.original.id, values);
    table.setEditingRow(null);
  },
  renderRowActions: ({ row, table }) => (
    <Box sx={{ display: 'flex', gap: '1rem' }}>
      <Tooltip title="Edit">
        <IconButton => table.setEditingRow(row)}>
          <EditIcon />
        </IconButton>
      </Tooltip>
      <Tooltip title="Delete">
        <IconButton color="error" => handleDelete(row.original.id)}>
          <DeleteIcon />
        </IconButton>
      </Tooltip>
    </Box>
  ),
});

5. Virtualization for Large Data

Enable row virtualization for 10,000+ rows.

const table = useMaterialReactTable({
  columns,
  data: largeDataset,
  enableRowVirtualization: true,
  rowVirtualizerOptions: { overscan: 5 },
  muiTableBodyRowProps: { sx: { height: 53 } }, // Fixed height for perf
});

Decision Tree

Dataset size?
├─ < 100 rows → Client-side (default)
├─ 100-10,000 rows → Server-side pagination
└─ > 10,000 rows → Virtualization + server-side

Common Configurations

Customization

Toolbar

renderTopToolbar: ({ table }) => (
  <Box sx={{ display: 'flex', gap: 2, p: 2 }}>
    <MRT_GlobalFilterTextField table={table} />
    <ExportButton data={data} />
  </Box>
),

Row Styling

muiTableBodyRowProps: ({ row }) => ({
  sx: { backgroundColor: row.original.isHighlighted ? 'action.hover' : undefined },
}),

Localization

import { MRT_Localization_ES } from 'material-react-table/locales/es';

localization: MRT_Localization_ES,

Filter Variants

React Query Integration

function UsersTable() {
  const [columnFilters, setColumnFilters] = useState<MRT_ColumnFiltersState>([]);
  const [globalFilter, setGlobalFilter] = useState('');
  const [sorting, setSorting] = useState<MRT_SortingState>([]);
  const [pagination, setPagination] = useState({ pageIndex: 0, pageSize: 10 });

  const { data, isLoading, isError } = useQuery({
    queryKey: ['users', columnFilters, globalFilter, pagination, sorting],
    queryFn: () => fetchUsers({ columnFilters, globalFilter, pagination, sorting }),
    placeholderData: keepPreviousData,
  });

  const table = useMaterialReactTable({
    columns,
    data: data?.users ?? [],
    rowCount: data?.meta?.totalRowCount ?? 0,
    manualFiltering: true,
    manualPagination: true,
    manualSorting: true,
    state: { columnFilters, globalFilter, isLoading, pagination, showAlertBanner: isError, sorting },
    onColumnFiltersChange: setColumnFilters,
    onGlobalFilterChange: setGlobalFilter,
    onPaginationChange: setPagination,
    onSortingChange: setSorting,
  });

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

Anti-Patterns

Dependencies

npm install material-react-table @mui/material @mui/x-date-pickers @mui/icons-material @emotion/react @emotion/styled @tanstack/react-query

Version Compatibility

MUI v7 Status: ⚠️ Not officially supported yet. Known issues: dark mode broken, TypeScript errors. Use --legacy-peer-deps if required. Track GitHub #1401.

Key V2→V3 changes: text → label in select options, keyboard nav enabled by default.

Checklist

• Columns wrapped in useMemo
• Proper accessors (accessorKey | accessorFn + id)
• filterVariant set per column type
• Server-side for > 100 rows
• Virtualization for > 10k rows
• isLoading state connected
• Error states handled (showAlertBanner)
• Validation in onEditingRowSave
• Row actions labeled for a11y
• LocalizationProvider if using date filters
• Version-appropriate props (V1→V2→V3 renames)
• z-index handled if table in modal/drawer
