    top: BorderSide(color: Color(0xFF999999)),
    left: BorderSide(color: Color(0xFF999999)),
    right: BorderSide(color: Color(0xFF999999)),
  ),
  headerBorder: Border.all(color: Color(0xFF999999)),
  rowBorder: Border.all(color: Color(0xFF999999)),

  addRowIcon: Icon(
    Icons.add_circle_outline,
    size: 24.0,
    color: Colors.white,
  ),
  addRowIconContainerBackgroundColor: Colors.blueAccent,
