        {
            case DataControlRowType.Header:
                //第一行表头
                TableCellCollection tcHeader = e.Row.Cells;
                tcHeader.Clear();

                tcHeader.Add(new TableHeaderCell());
                //跨3行
                tcHeader[0].Attributes.Add("rowspan", "3");
                tcHeader[0].Attributes.Add("bgcolor", "white");
                tcHeader[0].Text="";

                tcHeader.Add(new TableHeaderCell());
                //跨6列
                tcHeader[1].Attributes.Add("colspan", "6");
                tcHeader[1].Text = "全部信息</th</tr><tr>";

                //第二行表头
                tcHeader.Add(new TableHeaderCell());
                tcHeader[2].Attributes.Add("bgcolor", "DarkSeaGreen");
                tcHeader[2].Text = "身份证号码";

                tcHeader.Add(new TableHeaderCell());

                tcHeader[3].Attributes.Add("colspan", "2");
                tcHeader[3].Text = "基本信息";

                tcHeader.Add(new TableHeaderCell());
                tcHeader[4].Attributes.Add("bgcolor", "DarkSeaGreen");

                tcHeader[5].Text = "联系方式</th></tr><tr>";

                //第三行表头
                tcHeader.Add(new TableHeaderCell());
                tcHeader[6].Attributes.Add("bgcolor", "Khaki");
                tcHeader[6].Text = "身份证号码";

                tcHeader.Add(new TableHeaderCell());
                tcHeader[7].Attributes.Add("bgcolor", "Khaki");
                tcHeader[7].Text = "姓名";

                tcHeader[9].Attributes.Add("bgcolor", "Khaki");
                tcHeader[9].Text = "薪水";

                tcHeader.Add(new TableHeaderCell());
                tcHeader[10].Attributes.Add("bgcolor", "Khaki");
                tcHeader[10].Text = "家庭住址";
