我想将网页的数据导出到一个固定格式的Excel表中，应该怎么操作呢？
说白了，就是如何控制数据写入Excel指定的单元格？Excel中已经有固定表，只需要向表中的相关单元格填写数据就行了。
而不需要一股脑将网页所有数据都横七竖八的写到Excel中，谢谢。

Response.Clear();
Response.Buffer = true;
Response.Charset = "gb2312";
Response.AppendHeader("Content-Disposition", "attachment;filename=users.xls");
Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");
Response.Write("<meta http-equiv=Content-Type content=text/html;charset=gb2312>"); 
this.EnableViewState = false;
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
this.GridView1.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString());
Response.End();
