AdaptTable for Base UI

Large datasets in Base UI

Turn virtualize on and the table renders the rows in view plus a small overscan, whatever the dataset's size. virtualizeColumns 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";

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

• Row grouping in Base UI — Nested group headers with counts, subtotals, footers and collapse state.
• Nested tables in Base UI — A real table under a row — same engine, own columns, own keys.
• Export and print in Base UI — CSV, XLSX and PDF from one seam — plus a real print layout.
• Tree data in Base UI — Rows that contain rows — nesting, chevrons, keyboard traversal.
• Mobile cards in Base UI — Every row becomes a card on phones. Automatically, with the same state.
• Pivot tables in Base UI — Rows down the side, dimensions across the top, subtotals at every level.
