【问题描述】：
我有两个脚本，一个成功地将行和列的颜色和样式导出到 xlsx，其中包含类和行 css。我有一个更复杂的脚本，可以导出多个工作表，我想对其应用样式。但是，第二个不起作用。我觉得问题在于 javascript，尤其是模板部分，否则我看不出有什么区别。这是一个有效的方法：
<script src="https://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script type="text/javascript">
var tableToExcel = (function () {
// Define your style class template.
var style = "<style>.green { background-color: green; }</style>";
var uri = 'data:application/vnd.ms-excel;base64,'
, template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]-->' + style + '</head><body><table>{table}</table></body></html>'
, base64 = function (s) {
return window.btoa(unescape(encodeURIComponent(s)))
}
, format = function (s, c) {
return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; })
}
return function (table, name) {
if (!table.nodeType) table = document.getElementById(table)
var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }
window.location.href = uri + base64(format(template, ctx))
}
})()
</script>
<style type="text/css">
.green
{
background-color: green;
}
</style>
<input type="button" onclick="tableToExcel('testTable', 'W3C Example Table', 'testTable2', 'This is a test')" value="Export to Excel" />
<table id="testTable" summary="Code page support in different versions of MS Windows."
rules="groups" frame="hsides" border="2">
<caption>
CODE-PAGE SUPPORT IN MICROSOFT WINDOWS
</caption>
<colgroup align="center"></colgroup>
<colgroup align="left"></colgroup>
<colgroup span="2" align="center"></colgroup>
<colgroup span="3" align="center"></colgroup>
<thead valign="top">
<tr>
<th>Code-Page<br />ID</th>
<th>Name</th>
<th>ACP</th>
<th>OEMCP</th>
<th>Windows<br />NT 3.1</th>
<th>Windows<br />NT 3.51</th>
<th>Windows<br />95</th>
</tr>
</thead>
<tbody>
<tr>
<td>1200</td>
<td style="background-color: #00f; color: #fff">Unicode (BMP of ISO/IEC-10646)</td>
<td></td>
<td></td>
<td>X</td>
<td>X</td>
<td>*</td>
</tr>
这是一个没有错误的脚本，只是不会在相同的 html 元素上发布样式：
