Question

我在c＃中有一个填充数据的网格。该网格中的一列包含按字母顺序排序的字母（后跟数字），如下所示：

A124
A256
A756
B463
B978
D322
etc.

我需要以word文档（.doc或.docx格式）导出此数据。这是我导出一个signle网格所做的：

var dt = FuntionThatReturnsDatatables();

var gd = new GridView
        {
            DataSource = dt                     
        };

        gd.DataBind();

        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.Buffer = true;

        HttpContext.Current.Response.AddHeader("content-disposition", "attachment;
        filename=" + "List" + DateTime.Now.ToString("dd.MM.yyyy") + ".doc");

        HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
        HttpContext.Current.Response.ContentType = "application/ms-word";
        HttpContext.Current.Response.Charset = "UTF-8";

      HttpContext.Current.Response.BinaryWrite(System.Text.Encoding.UTF8.GetPreamble()); 

        var oStringWriter = new StringWriter();
        var oHtmlTextWriter = new HtmlTextWriter(oStringWriter);

        gd.RenderControl(oHtmlTextWriter);
        HttpContext.Current.Response.Output.Write(oStringWriter.ToString());
        HttpContext.Current.Response.Flush();
        HttpContext.Current.Response.End();

但现在我必须遵循这个逻辑： - 对于网格中的每个字母，应创建一个带有标题的新表：
