后台：

{
if (e.Row.RowType == DataControlRowType.Header)
{
//e.Row.Cells[0].Text = "<input id='Checkbox2' type='checkbox' onclick='CheckAll()'/><label></label>";
GridViewRow gr = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);
string HeaderBackColor = "#EDEDED";
gr.BackColor = System.Drawing.ColorTranslator.FromHtml(HeaderBackColor);
Literal newCells = new Literal();
newCells.Text += @"

<th rowspan='2'>合同号</th>
<th rowspan='2'>项目名称</th>
<th rowspan='2'>项目级别</th>
<th rowspan='2'>是否9000</th>

</tr>
<tr bgcolor='" + HeaderBackColor + "'>";
newCells.Text += @"

";
TableCellCollection cells = e.Row.Cells;
TableHeaderCell headerCell = new TableHeaderCell();
//下面的属性设置与 <td rowspan='2'>关键单元格</td> 要一致
headerCell.RowSpan = 2;
headerCell.Controls.Add(newCells);
gr.Cells.Add(headerCell);
gr.Cells.Add(headerCell);
gr.Visible = true;
//添加到 GridView1
this.gridView.Controls[0].Controls.AddAt(0, gr);
}
}
效果：
