luckysheet+luckyexcel在线预览excel

luckysheet,是一款纯前端的在线excel,功能强大,完全开源
如果在线预览excel的需求,可以使用xlsx插件,但是这个插件只能解析表格中的数据,如果表格中的样式和数据都要解析出来,就需要luckysheet+luckyexcel方案,下面整理一下,vue项目中怎么使用
1.luckysheet需要手动引入相关文件

<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet/dist/plugins/css/pluginsCss.css' />
<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet/dist/plugins/plugins.css' />
<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet/dist/css/luckysheet.css' />
<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet/dist/assets/iconfont/iconfont.css' />
<script src="https://cdn.jsdelivr.net/npm/luckysheet/dist/plugins/js/plugin.js"></script>
<script src="https://cdn.jsdelivr.net/npm/luckysheet/dist/luckysheet.umd.js"></script>

2.安装luckyexcel,npm i luckyexcel
3.写一个vue组件测试一下,根据luckysheet官方文档和demo可以进行配置,里面有很多配置,下面的代码是参考官方demo的,删减了一下,主要需求是打开本地excel,先看一下打开效果(本地excel带样式的,在线打开还是带样式的)
在这里插入图片描述

    <div style="position: absolute; top: 0">
      <input style="font-size: 16px" type="file" @change="uploadExcel" />
