------解决方案--------------------

你这是吧页面上的table组成的html导出成excel 么,如果这样的话是不是页面的html转换到流文件时候html标签出了问题呢?

------解决方案--------------------

先参考这个， 我找下我上次解决方法的代码
private void Export(GridView _gv, string FileName)
   {
       Response.Clear();
       Response.Buffer = true;
       Response.Charset = "GB2312";
       Response.Write("<meta http-equiv=Content-Type content=text/html;charset=GB2312>");
       Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());//FileName.xls");
       Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
       Response.ContentType = "application/vnd.xls";//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);
       _gv.RenderControl(oHtmlTextWriter);
       Response.Output.Write(oStringWriter.ToString());
       Response.Flush();
       Response.End();

   }
   public override void VerifyRenderingInServerForm(Control control)
   {
   }

       this.GridView1.DataBind();
