Material React Table

MRT v1.4 and v1.5 have major virtualization upgrades after switching to @tanstack/react-virtual v3.0!

Virtualization is useful when you have a lot of data you want to display client-side all at once without having to use pagination. Material React Table makes this as simple as possible, thanks to @tanstack/react-virtual with both row virtualization and column virtualization support.

NOTE: You should only enable row virtualization if you have a large number of rows. Depending on the size of the table, if you are rendering less than a couple dozen rows at a time, you will actually just be adding extra overhead to the table renders. Virtualization only becomes necessary when you have more than 50 rows or so at the same time with no pagination.

Virtualization, or virtual scrolling, works by only rendering the rows or columns that are visible on the screen. This is useful for performance and user experience, as we can make it appear that there are hundreds, thousands, or even tens of thousands of rows in the table all at once, but in reality, the table will only render the couple dozen rows that are visible on the screen, or the handful of columns that are visible on the screen.

For more reading on the concept of virtualization, we recommend this blog post by LogRocket.

If your table is paginated or you are not going to render more than 50 rows at once, you probably do not need row virtualization.

If your table does not have more than 12 columns, you probably do not need column virtualization.

There is a slight amount of extra overhead that gets added to your table's rendering when virtualization is enabled, so do not just enable it for every table. That being said, if your table does have well more than 100 rows that it is trying to render all at once without pagination, performance should improve significantly once it has been enabled.

Enabling row virtualization is as simple as setting the enableRowVirtualization table option to true. However, you will probably also want to turn off pagination, which you can do by setting enablePagination to false.

<MaterialReactTable
  columns={columns}
  data={data}
  enablePagination={false}
  enableRowVirtualization
/>

Take a look at the example below with 10,000 rows!

1import { useEffect, useMemo, useRef, useState } from 'react';
2import {
3  MaterialReactTable,
4  useMaterialReactTable,
5  type MRT_ColumnDef,
6  type MRT_SortingState,
7  type MRT_Virtualizer,
8} from 'material-react-table';
9import { makeData, type Person } from './makeData';
10
11const Example = () => {
12  const columns = useMemo<MRT_ColumnDef<Person>[]>(
13    //column definitions...
14    () => [
15      {
16        accessorKey: 'firstName',
17        header: 'First Name',
18        size: 150,
19      },
20      {
21        accessorKey: 'middleName',
22        header: 'Middle Name',
23        size: 150,
24      },
25      {
26        accessorKey: 'lastName',
27        header: 'Last Name',
28        size: 150,
29      },
30      {
31        accessorKey: 'email',
32        header: 'Email Address',
33        size: 300,
34      },
35      {
36        accessorKey: 'address',
37        header: 'Address',
38      },
39      {
40        accessorKey: 'zipCode',
41        header: 'Zip Code',
42      },
43      {
44        accessorKey: 'city',
45        header: 'City',
46      },
47      {
48        accessorKey: 'state',
49        header: 'State',
50      },
51      {
52        accessorKey: 'country',
53        header: 'Country',
54      },
55    ],
56    [],
57    
58  );
59
60  //optionally access the underlying virtualizer instance
61  const rowVirtualizerInstanceRef =
62    useRef<MRT_Virtualizer<HTMLDivElement, HTMLTableRowElement>>(null);
63
64  const [data, setData] = useState<Person[]>([]);
65  const [isLoading, setIsLoading] = useState(true);
66  const [sorting, setSorting] = useState<MRT_SortingState>([]);
67
68  useEffect(() => {
69    if (typeof window !== 'undefined') {
70      setData(makeData(10_000));
71      setIsLoading(false);
72    }
73  }, []);
74
75  useEffect(() => {
76    //scroll to the top of the table when the sorting changes
77    try {
78      rowVirtualizerInstanceRef.current?.scrollToIndex?.(0);
79    } catch (error) {
80      console.error(error);
81    }
82  }, [sorting]);
83
84  const table = useMaterialReactTable({
85    columns,
86    data, //10,000 rows
87    enableBottomToolbar: false,
88    enableGlobalFilterModes: true,
89    enablePagination: false,
90    enableRowNumbers: true,
91    enableRowVirtualization: true,
92    muiTableContainerProps: { sx: { maxHeight: '600px' } },
93    onSortingChange: setSorting,
94    state: { isLoading, sorting },
95    rowVirtualizerInstanceRef, //optional
96    rowVirtualizerOptions: { overscan: 5 }, //optionally customize the row virtualizer
97  });
98
99  return <MaterialReactTable table={table} />;
100};
101
102export default Example;
103

Enabling column virtualization is also as simple as setting the enableColumnVirtualization table option to true.

<MaterialReactTable columns={columns} data={data} enableColumnVirtualization />

Take a look at the example below with 500 columns!

1import { useRef } from 'react';
2import {
3  MaterialReactTable,
4  useMaterialReactTable,
5  type MRT_Virtualizer,
6} from 'material-react-table';
7import { fakeColumns, fakeData } from './makeData';
8
9const Example = () => {
10  //optionally access the underlying virtualizer instance
11  const columnVirtualizerInstanceRef =
12    useRef<MRT_Virtualizer<HTMLDivElement, HTMLTableCellElement>>(null);
13
14  const table = useMaterialReactTable({
15    columnVirtualizerInstanceRef, //optional
16    columnVirtualizerOptions: { overscan: 4 }, //optionally customize the virtualizer
17    columns: fakeColumns, //500 columns
18    data: fakeData,
19    enableColumnVirtualization: true,
20    enableColumnPinning: true,
21    enableRowNumbers: true,
22  });
23
24  return <MaterialReactTable table={table} />;
25};
26
27export default Example;
28

WARNING: Do not enable row or column virtualization conditionally. This could break React's Rule of Hooks and/or cause other UI jumpiness.

When either row or column virtualization is enabled, a few other props automatically get set internally.

In MRT Versions 1.3 and earlier, a CSS table-layout: fixed style was automatically added to the <table> element to prevent columns from wiggling back and forth during scrolling due to body cells having varying widths.

But now in MRT Versions 1.4 and later, the layoutMode table option is automatically set to the 'grid' value when either row or column virtualization is enabled, which means that all of the table markup will use CSS Grid and Flexbox instead of the traditional semantic styles that usually come with table tags. This is necessary to make the virtualization work properly with decent performance.

The enableStickyHeader table option is automatically set to true when row virtualization is enabled. This keeps the table header sticky and visible while scrolling and adds a default max-height of 100vh to the table container.

You can adjust some of the virtualizer props that are used internally with the rowVirtualizerOptions and columnVirtualizerOptions props. The most useful virtualizer props are the overscan and estimateSize options. You may want to adjust these values if you have unusual row heights or column widths that are causing the default scrolling to behave strangely.

<MaterialReactTable
  columns={columns}
  data={data}
  enableColumnVirtualization
  enablePagination={false}
  enableRowVirtualization
  columnVirtualizerOptions={{
    overscan: 5, //adjust the number of columns that are rendered to the left and right of the visible area of the table
    estimateSize: () => 400, //if your columns are wider or , try tweaking this value to make scrollbar size more accurate
  }}
  rowVirtualizerOptions={{
    overscan: 10, //adjust the number or rows that are rendered above and below the visible area of the table
    estimateSize: () => 100, //if your rows are taller than normal, try tweaking this value to make scrollbar size more accurate
  }}
/>

See the official TanStack Virtualizer Options API Docs for more information.

MRT v1.4 upgraded from react-virtual v2 to @tanstack/react-virtual v3.0, which has some breaking changes and virtualizer option name changes. TypeScript hints should help you with any prop name changes, but you can also view the official TanStack Virtual Docs for guidance.

In a similar way that you can access the underlying table instance, you can also access the underlying virtualizer instances. This can be useful for accessing methods like the scrollToIndex method, which can be used to programmatically scroll to a specific row or column.

const columnVirtualizerInstanceRef = useRef<Virtualizer>(null);
const rowVirtualizerInstanceRef = useRef<Virtualizer>(null);

useEffect(() => {
  if (rowVirtualizerInstanceRef.current) {
    //scroll to the top of the table when sorting changes
    rowVirtualizerInstanceRef.current.scrollToIndex(0);
  }
}, [sorting]);

return (
  <MaterialReactTable
    columns={columns}
    data={data}
    enableColumnVirtualization
    enableRowVirtualization
    rowVirtualizerInstanceRef={rowVirtualizerInstanceRef}
    columnVirtualizerInstanceRef={columnVirtualizerInstanceRef}
  />
);

See the official TanStack Virtualizer Instance API Docs for more information.
