How to remove default bottom devider from DataTable() widget

here is my code

return SingleChildScrollView(
  scrollDirection: Axis.vertical,
  child: SingleChildScrollView(
    scrollDirection: Axis.horizontal,
    child: DataTable(
      dividerThickness: 0,
        decoration: BoxDecoration(
            border: Border.all(
          width: 1,
          color: Color(0xFFE6E7EB),
        )),
        columns: [
          DataColumn(label: Text('RollNo')),
          DataColumn(label: Text('Name')),
        ],
        rows: [
          DataRow(cells: [
            DataCell(Text('1')),
            DataCell(Text('Arya')),
          ]),
          DataRow(cells: [
            DataCell(Text('1')),
            DataCell(Text('Arya')),
          ])
        ]),
  ),
);

I tried to set devider thickness value to 0 but it still shows some border bellow it

wrap your DataTable with the Theme widget and change the divide color to transparent also set dividerThickness to 0 in DataTable like this :

Widget build(BuildContext context) {
    return Theme(
      data: Theme.of(context).copyWith(dividerColor: Colors.transparent),
       child:DataTable(
       dividerThickness:0.0,
      columns: const <DataColumn>[
        DataColumn(
          label: Text(
            'Name',
            style: TextStyle(fontStyle: FontStyle.italic),
          ),
        ),
        DataColumn(
          label: Text(
            'Age',
            style: TextStyle(fontStyle: FontStyle.italic),
          ),
        ),
        DataColumn(
          label: Text(
            'Role',
            style: TextStyle(fontStyle: FontStyle.italic),
          ),
        ),
      ],
      rows: const <DataRow>[
        DataRow(
          cells: <DataCell>[
            DataCell(Text('Sarah')),
            DataCell(Text('19')),
            DataCell(Text('Student')),
          ],
        ),
        DataRow(
          cells: <DataCell>[
            DataCell(Text('Janine')),
            DataCell(Text('43')),
            DataCell(Text('Professor')),
          ],
        ),
        DataRow(
          cells: <DataCell>[
            DataCell(Text('William')),
            DataCell(Text('27')),
            DataCell(Text('Associate Professor')),
          ],
        ),
      ],
    ));
  }
