当html表从asp.net导出到excel时，会显示该表，但下面没有显示表中的内容是我的代码。
protected void btnExportToExcel_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
lblCategorystatusReportHeader.Visible = true;
Response.AddHeader("content-disposition",
"attachment;filename=StatusReport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
//Panel preOrderPanel = (Panel)rpt1.FindControl("pnlPreOrder");
//rptCP.RenderControl(hw);
//pnlPreOrder.RenderControl(hw);
order.RenderControl(hw);
string output = sw.ToString();
output = "<html><head><meta charset=" + Encoding.UTF8.WebName + " /></head><body>" + output + "</body></html>";
Response.Output.Write(output);
Response.Flush();
Response.End();
lblCategorystatusReportHeader.Visible = false;
}
