AdaptTable for Radix

Row grouping in Radix

Pass groupBy and rows fold into Radix group headers with counts. Pass a list and each key nests inside the one before it, however deep the nesting goes.

groupAggregates adds per-group subtotals from the same mapper summaryRow uses, so every header totals its whole subtree and groupFooters closes each group with the same numbers.

Collapse state travels in the URL, and export writes the grouped sheet — outline levels and all — rather than the flat rows underneath it.

A group header is a real Table.Row with a spanning cell, and its toggle wraps the engine's chevron — which points by writing direction rather than rotating, so it reads correctly right-to-left.

The code

import { DataTable } from "@adapttable/radix";

export function People({ rows, columns }) {
  return (
    <DataTable
      data={rows}
      columns={columns}
      rowKey={(row) => row.id}
      groupBy={["team", "status"]}
      groupFooters
      groupAggregates={(group) => ({
        budget: group.reduce(
          (sum, row) => sum + row.budget,
          0
        ),
      })}
    />
  );
}
