AdaptTable for Base UI

Row and column virtualization in Base UI

Compose virtualize() and the table renders the rows in view plus a small overscan, whatever the dataset's size. virtualize({ virtualizeColumns: true }) does the same across, for column sets far wider than the window.

The header stays pinned, pinned columns stay put, and the scroll box scrolls — never the page. Sorting, filtering and selection keep working on the whole dataset rather than on what is drawn.

Nothing about the markup changes: it is the same Base UI table, with the rows outside the window absent rather than hidden.

The scroll box is the adapter's own element with an injected rule that lets the inner table exceed it, the header sticks by inline rule, and pinned cells take their opaque background from the adapter's surface token.

The code

import { DataTable } from "@adapttable/base-ui";
import { virtualize } from "@adapttable/base-ui/virtualize";

export function Ledger({ rows, columns }) {
  return (
    <DataTable
      data={rows}
      columns={columns}
      rowKey={(row) => row.id}
      features={[virtualize({ virtualizeColumns: true })]}
      maxHeight={600}
      defaultColumnLayout={{ pinned: { name: "start" } }}
    />
  );
}
