  @override
  Widget build(BuildContext context) {
    return Grid(
      columns: [
        GridColumn.autoFitWidth(text: "Hello"),
        GridColumn.autoFitWidth(text: "World"),
      ],
      rows: [
        GridRow(children: [
          GridCell.autoFitWidth(text: "123.12", sortValue: 123.12),
          GridCell.autoFitWidth(text: "12", sortValue: 12),

Selectable Rows, Highlighted Rows

On Desktop and web, rows are by default highlighted when the mouse cursor is hovered over them. Rows can be selected by passing selectedRowIndex. Highlighted and selected styles can be configured in DataGridThemeData.

Frozen Headers

By default column headers are frozen, this means that row content will scroll underneath them.

By default row headers are frozen, however this can be disabled using hasRowHeader boolean.
