Fixed header

Set fixedHeader to keep the column headers visible while the user scrolls through a long dataset. The table body becomes independently scrollable within a container whose height is controlled by fixedHeaderScrollHeight.

import DataTable, { type TableColumn } from 'react-data-table-component';

const columns: TableColumn<Employee>[] = [
  { name: '#',          selector: r => r.id,         width: '60px' },
  { name: 'Name',       selector: r => r.name,       sortable: true },
  { name: 'Department', selector: r => r.department, sortable: true },
  { name: 'Salary',     selector: r => r.salary,     sortable: true,
    right: true, format: r => `$${r.salary.toLocaleString()}` },
  { name: 'Status',     selector: r => r.status },
];

<DataTable
  columns={columns}
  data={data}           // large dataset
  fixedHeader
  fixedHeaderScrollHeight="300px"
  highlightOnHover
/>

How it works

When fixedHeader is enabled, the responsive wrapper gains overflow-y: auto and the max-height you set via fixedHeaderScrollHeight. The column header row gets position: sticky; top: 0 so it remains in view as the body scrolls within that container.

Because the scroll container is the responsive wrapper, horizontal scrolling for wide tables continues to work normally. Both axes scroll together, but the header sticks on the vertical axis.

With pagination

Fixed header and pagination work together without any extra configuration. The scroll height only constrains the table body rows. The pagination bar sits below the responsive wrapper and is always fully visible.

<DataTable
  columns={columns}
  data={data}
  fixedHeader
  fixedHeaderScrollHeight="400px"
  pagination
  paginationPerPage={20}
/>

With selection

The checkbox column header scrolls with all other headers and stays fixed. The select-all checkbox remains accessible at the top of the scrollable area.

<DataTable
  columns={columns}
  data={data}
  fixedHeader
  fixedHeaderScrollHeight="350px"
  selectableRows
/>
