vue3+luckyexcel+php在线编辑excel文件-编程知识

开发过程中，需要开发一个在线编辑excel文档的功能，找到了这个合适的组件

Luckysheet ，一款纯前端类似excel的在线表格，功能强大、配置简单、完全开源。

可以导入文档，预览、编辑、保存、导出等功能，可以满足大部分需求

第一步：需要先安装 vue3 运行下面三个安装命令

npm install exceljs -S
npm install luckyexcel -S
npm install file-saver

第二步：前端部分index.html 加入引用代码

<link rel='stylesheet' href='/luckysheet/pluginsCss.css' /><link rel='stylesheet' href='/luckysheet/plugins.css' /><link rel='stylesheet' href='/luckysheet/luckysheet.css' /><link rel='stylesheet' href='/luckysheet/iconfont.css' /><script src="/luckysheet/plugin.js"></script><script src="/luckysheet/luckysheet.umd.js"></script>
