在導出之前添加標題Excel

Question

正在使用以下函數導出Excel文件。它工作正常。我從SQL數據庫檢索記錄到數據表，並導出Excel工作表。

 public ActionResult ExporttoExcel() 
     { 
      DataTable dt = new DataTable(); 
      SqlConnection con = new SqlConnection("Connection string here"); 
      con.Open(); 
      SqlCommand cmd = new SqlCommand("select * from Exportxcel", con); 
      dt.Load(cmd.ExecuteReader()); 
      int total = 0; 
      foreach (DataRow row in dt.Rows) 
      { 
       int salaryvalue = Convert.ToInt32(row["Salary"]); 
       total = salaryvalue + total; 
      } 
      dt.Rows.Add(new object[] { "", "Total", total }); 


      if (dt.Rows.Count > 0) 
      { 
       string filename = "ExcelExport.xls"; 
       System.IO.StringWriter tw = new System.IO.StringWriter(); 
       System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw); 
       DataGrid dgGrid = new DataGrid(); 
       dgGrid.DataSource = dt; 
       dgGrid.DataBind(); 
       dgGrid.RenderControl(hw); 
       Response.ContentType = "application/vnd.ms-excel"; 
       Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + ""); 
       Response.Write(tw.ToString()); 
       Response.End(); 
      } 
      return View(dt); 
     } 

我的問題是我需要的值綁定之前增加兩個冠軍？如何做到這一點？我需要添加標題，如下面的屏幕Shot.How筆者要做到這一點？

你可以嘗試加入這個剛剛宣佈System.Web.UI.HtmlTextWriter HW

hw.Write("<table><tr><td colspan='3'>Title</td></tr>") 
hw.Write("<table><tr><td colspan='3'>Author</td></tr>")
