        firstHeaderCell: ExpandableTableCell(child: Container()),
        headers: [],
        rows: [],
        headerHeight: 263,
        defaultsColumnWidth: 200,
        firstColumnWidth: 300,
        scrollShadowColor: AppColors.black,
      );
      super.initState();
    }
    void _onEvent(){    
      controller.rows.add(...your code...);
    }
