$("#btnAdd").click(function () {
                var $tr = $("<tr>");
                $tr.append("<td>Ravi</td><td>50</td><td>G@gmail.com</td><td>1000000</td>");
                $("#tbl tbody").append($tr);
                $("#txthidden").val($("#divTable").html());
                $("#txthidden").val().replace("<table>", "swe");
            });

`我有一个封装在div标签内的html表。我需要将数据导出到excel。为此，我发布了页面，并在其帖子上放了一些c＃代码用于导出相同的内容。为了得到表格数据，我使用了代码

        Response.ContentType = "application/force-download";
        Response.AddHeader("content-disposition", "attachment;    filename=Print.xls");
        Response.Write("<html xmlns:x=\"urn:schemas-microsoft-com:office:excel\">");
        Response.Write("<head>");
        Response.Write("<META http-equiv=\"Content-Type\"       content=\"text/html; charset=utf-     8\">");
        Response.Write("<!--[if gte mso 9]><xml>");
        Response.Write("<x:ExcelWorkbook>");
        Response.Write("<x:ExcelWorksheets>");
        Response.Write("<x:ExcelWorksheet>");
        Response.Write("<x:Name>Report Data</x:Name>");
        Response.Write("<x:WorksheetOptions>");
        Response.Write("<x:Print>");
        Response.Write("<x:ValidPrinterInfo/>");
        Response.Write("</x:Print>");
        Response.Write("</x:WorksheetOptions>");
        Response.Write("</x:ExcelWorksheet>");
        Response.Write("</x:ExcelWorksheets>");
        Response.Write("</x:ExcelWorkbook>");
        Response.Write("</xml>");
        Response.Write("<![endif]--> ");
        StringWriter tw = new StringWriter();
        HtmlTextWriter hw = new HtmlTextWriter(tw);
        divTable.RenderControl(hw);
        Response.Write(tw.ToString());
        Response.Flush();
        Response.End();

这很好。但是如果我使用jquery在表中添加一行，则在回发期间不会在服务器端反映出来。我尝试了另一种方法，将表的内部Html存储到隐藏文本框并发布表单。但最终显示服务器错误消息“从客户端检测到潜在危险的Request.Form值”。

有没有办法完成我打算做的事情

<div id="divtbl" runat="server">
  <table id="tbl">
    <thead>
      <tr>
        <th>Name</th>
        <th>Age</th>
        <th>Mail</th>
        <th>Number</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td>Raj</td>
        <td>25</td>
        <td>Raj@gmail.com</td>
        <td>9999999</td>
      </tr>
      <tr>
        <td>Gopu</td>
        <td>29</td>
        <td>Goups@gmail.com</td>
        <td>9749612767</td>
      </tr>
    </tbody>
  </table>
