在 JavaScript 中导出时，Excel 中不支持 HTML 内容

Question

我想使用 javascript 库将 html 内容导出到 excel 中。代码如下。

<script src="plugins/JavascriptExcel.js"></script>
<div id="tbl1"><h1>Table 1</h1>
<table><tr><td>Product ID</td></tr>
<tr><td>111</td></tr>    
</table>
</div>
<div id="tbl2"><h1>Table 2</h1>
<table><tr><td>Product ID</td></tr>
<tr><td>211</td></tr>    
</table>
</div>
<button  onclick="tablesToExcel(['tbl1','tbl2'], ['Product1','Product2'], 'document.xls', 'Excel')">Export to Excel</button>

导出未完成。如果我只使用表格标签，它将起作用。但不支持div 标签。请告诉我解决方案。
