效果如下图，表头13-1 到13-11 也是动态绑定的。

 

 

   protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.Header)
            {
                TableCellCollection tcHeader = e.Row.Cells;//获取表头行的所有单元
                tcHeader.Clear();//清空原有的表头信息

                TableHeaderCell th = null;//
                for (int i = 1; i <= 10; i++)
                {//模拟建10个子列
                    th = new TableHeaderCell();
                    th.Text = "方案_" + i;
                    th.Width = 80;
                    tcHeader.Add(th);

                }
                GridViewRow rowHeader = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);//建一个表头行
                TableHeaderCell th2;
                th2 = new TableHeaderCell();
                th2.RowSpan = 2;
                th2.Text = "日期";
                th2.Width = 100;
                rowHeader.Cells.Add(th2);
                //
                th2 = new TableHeaderCell();
                th2.ColumnSpan = 10;
                th2.Text = "发车方案";
                rowHeader.Cells.Add(th2);
                //
                th2 = new TableHeaderCell();
                th2.RowSpan = 2;
                th2.Text = "修改";
                rowHeader.Cells.Add(th2);

                ((GridView)sender).Controls[0].Controls.AddAt(0, rowHeader);//加到gridview的第一行，也就是表头

            }
        }
