<script src="/xspreadsheet/xspreadsheet.js"></script>
<script src="/xspreadsheet/zh-cn.js"></script>
<script src="/xspreadsheet/xlsxspread.js"></script>
<script src="/sheetjs/xlsx.full.min.js"></script>

const xs = new Spreadsheet("#x-spreadsheet-demo")
var outputfilename="导出数据.xlsx";
var new_wb = xtos(xs.getData()); 
XLSX.writeFile(new_wb, outputfilename, {});
