asp GridView自己创建表头

 protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType== DataControlRowType.Header)
        {
            TableCellCollection Tcl = e.Row.Cells;

            Tcl.Clear();
            Tcl.Add(new TableHeaderCell());
            Tcl[0].RowSpan = 1;
            Tcl[0].Text = "编号";

            Tcl.Add(new TableHeaderCell());
          
            Tcl[1].RowSpan = 1;
            Tcl[1].Text = "产品";

            Tcl.Add(new TableHeaderCell());
            Tcl[2].ColumnSpan = 2;//表示战2个Column，2个列合并成一个列，并叫辣椒
            Tcl[2].RowSpan = 1;//表示占一行

            Tcl[2].Text = "辣椒";

            Tcl.Add(new TableHeaderCell());
            Tcl[3].ColumnSpan = 2;
            Tcl[3].RowSpan = 1;
            Tcl[3].Text = "苹果";
