@Smith, you mean you can't do this ? if you could share some code ...

Widget build(BuildContext context) {
    return Scaffold(
      body: DataTable(
        columns: [DataColumn(label: Text('label'))],
        rows: [
          DataRow(cells: [DataCell(
            Container(
              width: 200, //SET width
              child: Text('text')))
              ])
        ]
      ),
    );
