C#

string fileName = string.Empty;
       if (rdDailySales.Checked)
           fileName = rdDailySales.Text + "_" + DateTime.Now.Date.Day.ToString() + "_" + DateTime.Now.Date.Month.ToString() + "_" + DateTime.Now.Date.Year.ToString();
       else
           fileName = rdDsr.Text + "_" + DateTime.Now.Date.Day.ToString() + "_" + DateTime.Now.Date.Month.ToString() + "_" + DateTime.Now.Date.Year.ToString();
       Response.Clear();
       Response.Charset = "";
       Response.ContentEncoding = System.Text.UTF8Encoding.UTF8;
       Response.Cache.SetCacheability(HttpCacheability.NoCache);
       Response.ContentType = "application/ms-excel.xls";
       Response.AddHeader("content-disposition", "attachment;filename=" + fileName + ".xls");
       StringWriter sw = new StringWriter();
       HtmlTextWriter hw = new HtmlTextWriter(sw);
       firstRow.RenderControl(hw);
       //sencondRow.RenderControl(hw);
       if (rdDsr.Checked)
           dbReport.RenderControl(hw);
       //divbreak.RenderControl(hw);
       //thirdRow.RenderControl(hw);
       if (rdDailySales.Checked)
           dbReport1.RenderControl(hw);
       FileInfo fi = new FileInfo(Server.MapPath("../Styles/jquery.dataTablesExcel.css"));
       StringBuilder sb1 = new StringBuilder();
       StreamReader sr = fi.OpenText();
       while (sr.Peek() >= 0)
       {
           sb1.Append(sr.ReadLine());
       }
       sr.Close();
       Response.Write("<html><head><style type='text/css'>" + sb1.ToString() + "</style><head>" + sw.ToString() + "</html>");
       sw = null;
       hw = null;
       Response.Flush();
       Response.End();

Try filling the data from the first table into the second and check that it exports properly. That way you'll know if there is something in the data that is a problem.

Other then that, why don't you export to excel from the database, save the file on the server and simply provide the link for download? Wouldn't that be easier?
