您好：
通过JavaScript来导出数据为excel文档的方法，您可以尝试下此代码：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>EB页面导出为EXCEL文档的方法</title>
<script type="text/javascript">
<!-- download
function saveCode(obj) {
var winname = window.open('', '_blank', 'top=10000');
var strHTML = document.all.tableExcel.innerHTML;
winname.document.open('text/html', 'replace');
winname.document.writeln(strHTML);
winname.document.execCommand('saveas','','excel.xls');
winname.close();
}
-->
</script>
</head>
<body>
<div id="tableExcel">
<table id="test" width="100%" border="1" cellspacing="0" cellpadding="0">
<tr>
<td colspan="5" align="center">WEB页面导出为EXCEL文档的方法</td>
</tr>
<tr>
<td>列标题1</td>
<td>列标题2</td>
<td>列标题3</td>
<td>列标题4</td>
<td>列标题5</td>
</tr>
<tr>
<td>aaa</td>
<td>bbb</td>
<td>ccc</td>
<td>ddd</td>
<td>eee</td>
