         objstrbuild.Append("<body>");
         if (ds.Tables[0] != null && ds.Tables[0].Rows.Count > 0)
         {

             objstrbuild.Append("<table border='1'>");
             objstrbuild.Append("<tr>");
             for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
             {
                 objstrbuild.Append("<td style='border='1'>");





                     if (ds.Tables[0].Rows[i]["PositionCode"].ToString() != "*")
                     {


                         for (int j = Convert.ToInt16(ds.Tables[0].Rows[i]["PositionLevel"]); j>0 ; j--)
                         {

                             objstrbuild.Append("<div>");


                             objstrbuild.Append("<div  style='height:30px;padding:5px;width:150px;background-color: #67da67;'>");


                             for (int k = 0; k < ds.Tables[1].Rows.Count; k++)
                             {
                                 if (ds.Tables[0].Rows[i]["PositionID"].ToString() == ds.Tables[1].Rows[k]["PositionID"].ToString() && (j) == Convert.ToInt32(ds.Tables[1].Rows[k]["Level"]) && ds.Tables[0].Rows[i]["BlockNumber"].ToString() == ds.Tables[1].Rows[k]["Block"].ToString())
                                 {
                                     objstrbuild.Append(ds.Tables[1].Rows[k]["ContainerCode"].ToString());
                                     break;
                                 }

                             }


                                 objstrbuild.Append("</div>");


                                 objstrbuild.Append("<div style='font-weight:bold;'>");

                             objstrbuild.Append(ds.Tables[0].Rows[i]["PositionCode"].ToString() + "(Level-" + j.ToString() + ")");

                             objstrbuild.Append("</div>");


                             objstrbuild.Append("</div>");

                         }

                     }
                     else
                     {
                         objstrbuild.Append("<div>");
                         objstrbuild.Append("</div>");
                     }
                     objstrbuild.Append("</td>");
                 }


             objstrbuild.Append("</tr>");
             objstrbuild.Append("</table>");
         }
         objstrbuild.Append("</body>");
         objstrbuild.Append("</html>");


         Response.Clear();
         Response.AddHeader("Content-Disposition", "attachment;filename=" + "filename" + ".xls");
         Response.ContentType = "application/ms-excel";
         Response.ContentEncoding = System.Text.Encoding.Unicode;
         Response.BinaryWrite(System.Text.Encoding.Unicode.GetPreamble());

         Response.Cache.SetCacheability(HttpCacheability.NoCache); // not necessarily required

Missing required <title></title>

In <td style='border='1'> the style literal is missing its closing delimiter

I suggest that you place your desired HTML into a HTML page and try to display it before you start playing with StringBuilder. You might also consider using the W3C Markup Validation Service (http://validator.w3.org/).

Also, you are not using the style divBlockcss that you defined in the head
