        {


            Response.AddHeader("content-disposition", "inline; filename=\"Task Assignment.xls\"");
            Response.ContentType = "application/vnd.ms-excel";
            Response.Write("<html xmlns:x=\"urn:schemas-microsoft-com:office:excel\">");
            Response.Write("\r\n");

                string sep = "";
                foreach (DataColumn dc in dt1.Columns)
                {
                Response.Write("<style>.text { mso-number-format:\\@; } </style>");
                Response.Write(sep + dc.ColumnName);

                sep = "";
                for (i = 0; i < dt1.Columns.Count; i++)

                {

                Response.Write("<style>.text { mso-number-format:\\@; } </style>");
                Response.Write(sep + dr[i].ToString());
                sep = "\t";
                }
                Response.Write("\n");

                Response.End();
                }

输出是这样的:
EnrolmentNumber Coursecode标记0813001 EE2402 0813002 EE2402 0813003 EE2402 0813004 EE2402 0813005 EE2402 0813006 EE2402 0813007 EE2402 0813008 EE2402 0813009 EE2402 0813010 EE2402 0813011 EE2402 0813012 EE2402 0813013 EE2402 0813014 EE2402 0813015 EE2402 0813016 EE2402 0813017 EE2402 0813018 EE2402 0813019 EE2402 0813020 EE2402 0813021 EE2402 0813022 EE2402 0813023 EE2402 0813024 EE2402 0813025 EE2402 0813026

我想要的实际输出是:
入学人数课程代码标记
0813001 EE2402
0813002 EE2402
0813003 EE2402
0813004 EE2402

output is coming like this:
EnrolmentNumber Coursecode Marks 0813001 EE2402 0813002 EE2402 0813003 EE2402 0813004 EE2402 0813005 EE2402 0813006 EE2402 0813007 EE2402 0813008 EE2402 0813009 EE2402 0813010 EE2402 0813011 EE2402 0813012 EE2402 0813013 EE2402 0813014 EE2402 0813015 EE2402 0813016 EE2402 0813017 EE2402 0813018 EE2402 0813019 EE2402 0813020 EE2402 0813021 EE2402 0813022 EE2402 0813023 EE2402 0813024 EE2402 0813025 EE2402 0813026

Actual output i want is:
EnrolmentNumber Coursecode Marks
0813001 EE2402
0813002 EE2402
0813003 EE2402
0813004 EE2402
