//TableRow class in Flutter doesn't has height attribute. But the height of the TableRow is the maximum of the intrinsic height of all its children's.
//For example, you can has sizedBox classess for all TableCell classes inside the Table Row:
TableRow(
children: [
TableCell(
child: SizedBox(height: 5,),
),
TableCell(
child: SizedBox(height: 5,),
),
]),
