我有一个html表，其中包含一些包含下拉列表的单元格，我正在尝试使用table2excel jquery插件将其导出到Excel。该插件将导出所有单元格，但包含选择标记的单元格除外。我如何解决这个问题？
示例html：
<!DOCTYPE html>
<html>
<head>
<script type="javascript">
var tableToExcel = (function() {
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]--></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>
</head>
<body>
<input type="button" onclick="tableToExcel('testTable', 'W3C Example Table')" value="Export to Excel">
<table id="testTable" summary="Sample tabe to export to excel" rules="groups" frame="hsides" border="2">
<thead valign="top">
<tr>
<th>Col1</th>
<th>Col2</th>
</tr>
</thead>
<tbody>
<tr>
<td>Value1</td>
<td>
<select>
<option value="option1">Option 1</option>
<option value="option2" selected="selected">Option 2</option>
</select>
</td>
</tr>
</tbody>
</table>
</body>
</html>
您可以动态生成表格HTML，因此可以根据需要设置单元格的格式
