vue使用luckySheet前端excel的在线表格，导入显示以及导出excel文件

场景：

当界面上普通的element表格已经不足以展示的数据的时候，或是为了更好的体验。由后端处理数据为二进制文档流，返回到前端直接进行显示为excel。

效果图：

代码实现：

安装引入：

index.html还得引入一些东西,我的项目没有index.html，我就在mounted这样子引入了

 const script= document.createElement('script');script.type = 'text/javascript';script.src = `https://cdn.jsdelivr.net/npm/luckysheet/dist/plugins/js/plugin.js`;document.head.appendChild(script);const script1= document.createElement('script');script1.type = 'text/javascript';script1.src = `https://cdn.jsdelivr.net/npm/luckysheet/dist/luckysheet.umd.js`;document.head.appendChild(script1);

npm install luckyexcelimport LuckyExcel from 'luckyexcel'
