AdaptTable for shadcn

Row grouping in shadcn

Pass groupBy and rows fold into shadcn 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 row sits on bg-muted, and the footer flips the rule rather than the colour — same surface, a top border instead of a bottom one — so a group reads as opening and closing on the same note.

The code

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

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
        ),
      })}
    />
  );
}
