這個功能滿實用的，而且出乎意料的簡單，因為匯出成 html，副檔案是 .xls ，用Excel 開啟也都正常。
JSP export as excel example:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

</head>
<body>

String exportToExcel = request.getParameter("exportToExcel");
if (exportToExcel != null
&& exportToExcel.toString().equalsIgnoreCase("YES")) {
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition", "inline; filename="

}
