Grid或者DataTable中数据导出为Excel原来这么简单

Response.ClearContent();
Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");
Response.ContentType = "application/excel";
Response.Write(GetGridTableHtml(Grid1));
Response.End();2. 直接输出Html代码
Response.Write(@"
table border="1">
tr>
td>Excel/td>
td>By Html/td>
/tr>
/table>")
