C#导出EXCEL没有网格线的解决方法
2024-08-27 17:05:33
今天在做项目时，通过流导出数据到Excel却不显示网格线，真是郁闷。上网查了好久才得一良方（注意<XML>标签中的代码）：
DataTable thisTable = DBHelper.GetDataTable("select * from table");string sheetName = "sheetName";string fileName = "fileName";if (thisTable != null){ StringWriter sw = new StringWriter(); sw.WriteLine("<html xmlns:x=\"urn:schemas-microsoft-com:office:excel\">"); sw.WriteLine("<head>"); sw.WriteLine("<!--[if gte mso 9]>"); sw.WriteLine("<xml>"); sw.WriteLine(" <x:ExcelWorkbook>"); sw.WriteLine(" <x:ExcelWorksheets>"); sw.WriteLine(" <x:ExcelWorksheet>"); sw.WriteLine(" <x:Name>" + sheetName + "</x:Name>"); sw.WriteLine(" <x:WorksheetOptions>"); sw.WriteLine(" <x:Print>"); sw.WriteLine(" <x:ValidPrinterInfo />"); sw.WriteLine(" </x:Print>"); sw.WriteLine(" </x:WorksheetOptions>"); sw.WriteLine(" </x:ExcelWorksheet>"); sw.WriteLine(" </x:ExcelWorksheets>"); sw.WriteLine("</x:ExcelWorkbook>"); sw.WriteLine("</xml>"); sw.WriteLine("<![endif]-->"); sw.WriteLine("</head>"); sw.WriteLine("<body>"); sw.WriteLine("<table>"); sw.WriteLine(" <tr>"); sw.WriteLine(" <td><strong>列名0</strong></td>"); sw.WriteLine(" <td>列名1</td>"); sw.WriteLine(" <td>列名2</td>"); sw.WriteLine(" <td>列名3</td>"); sw.WriteLine(" <td>列名4</td>"); sw.WriteLine(" <td>列名5</td>"); sw.WriteLine(" </tr>"); foreach (DataRow dr in thisTable.Rows) { sw.WriteLine(" <tr>"); sw.WriteLine(" <td>" + dr["C0"] + "</td>"); sw.WriteLine(" <td>" + dr["C1"] + "</td>"); sw.WriteLine(" <td>" + dr["C2"] + "</td>"); sw.WriteLine(" <td>" + dr["C3"] + "</td>"); sw.WriteLine(" <td>" + dr["C4"] + "</td>"); sw.WriteLine(" <td>" + dr["C5"] + "</td>"); sw.WriteLine(" </tr>"); } sw.WriteLine("</table>"); sw.WriteLine("</body>"); sw.WriteLine("</html>"); sw.Close(); Response.Clear(); Response.Buffer = true; Response.Charset = "UTF-8"; this.EnableViewState = false; Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName +".xls"); Response.ContentType = "application/ms-excel"; Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312"); Response.Write(sw); Response.End();}
