Web页中table导出到execl（带模板）

  InitData();
                Response.Clear();
                Response.Buffer = true;
                Response.Charset = "GB2312";
                Response.AddHeader("Content-Disposition", "attachment;   filename=" + new AutoNumber().GetNumberByTime()+ ".xls");//这样的话，可以设置文件名为中文，且文件名不会乱码。其实就是将汉字转换成UTF8     

                // 如果设置为 GetEncoding("GB2312");导出的文件将会出现乱码！
                Response.ContentEncoding = System.Text.Encoding.UTF8;
                Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。 
                System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
                System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
                this.RenderControl(oHtmlTextWriter);//Add the Panel into the output Stream.
                //this.GridView1.RenderControl(oHtmlTextWriter);//将gridview输出，你也可以类似的写TextBox1.RenderControl...
                Response.Output.Write(oStringWriter.ToString());//Output the stream.
                Response.Flush();
                Response.End();
