AdaptTable for MUI

Spreadsheet formulas in MUI

A formula column is a column nobody wrote code for: type =ROUND(budget * 0.15, 0) and the table computes it per row, sorts it, filters it and exports it like any other column.

The engine covers arithmetic including POWER and SQRT, comparison, string joins, IF, and the aggregate functions a footer needs. A bad reference reports in the cell that caused it rather than blanking the table, and a circular reference reports #CYCLE! instead of recursing.

Formula columns serialize to the URL with everything else, so a derived column travels in the same link as the filters it sits beside.

There is no MUI-specific formula code: the engine returns ordinary column definitions, so a computed column is a TableCell like any other and an error value is the text inside it.

The code

import { DataTable } from "@adapttable/mui";
import { buildFormulaColumns } from "@adapttable/react/formula";

const derived = buildFormulaColumns([
  {
    key: "margin",
    header: "Margin",
    formula: "=ROUND(budget * 0.15, 0)",
  },
  {
    key: "tag",
    header: "Tag",
    formula: '=UPPER(team) & " · " & role',
  },
]);

export function People({ rows, columns }) {
  return (
    <DataTable
      data={rows}
      columns={[...columns, ...derived.columns]}
      rowKey={(row) => row.id}
    />
  );
}
