title: Excellentexport xlsx support
body: <p>I am using <a href="https://github.com/jmaister/excellentexport" rel="nofollow">Excellent Export</a> plugin to export my html table to xls excel file, and it is working great but I want to export my table to xlsx instead. Is there any support for that?</p>
  
  <p>I think it should be doable by changing </p>
  
  <pre><code>var uri = {excel: 'data:application/vnd.ms-excel;base64,', csv: 'data:application/csv;base64,'};
  var template = {excel: '&lt;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"&gt;&lt;head&gt;&lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8"&gt;&lt;!--[if gte mso 9]&gt;&lt;xml&gt;&lt;x:ExcelWorkbook&gt;&lt;x:ExcelWorksheets&gt;&lt;x:ExcelWorksheet&gt;&lt;x:Name&gt;{worksheet}&lt;/x:Name&gt;&lt;x:WorksheetOptions&gt;&lt;x:DisplayGridlines/&gt;&lt;/x:WorksheetOptions&gt;&lt;/x:ExcelWorksheet&gt;&lt;/x:ExcelWorksheets&gt;&lt;/x:ExcelWorkbook&gt;&lt;/xml&gt;&lt;![endif]--&gt;&lt;/head&gt;&lt;body&gt;&lt;table&gt;{table}&lt;/table&gt;&lt;/body&gt;&lt;/html&gt;'};
  </code></pre>
  
  <p>But not sure how to do this.</p>
  
  <p>Or is there any other easy way to export multiple tables into one excel sheet (xlsx)?</p>
