vue3+luckyexcel+php在线编辑excel文件

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>

组件部分test.vue

<template>
  <div style="position: absolute; top: 0">
    <input id="uploadBtn" type="file" @change="loadExcel" />
    <button class="btn" @click="getExcel">后台数据</button>
    <span>Or文件:</span>

    <select v-model="selected" @change="selectExcel">
      <option disabled value="">Choose</option>
      <option v-for="option in options" :key="option.text" :value="option.value">
        {{ option.text }}
      </option>
    </select>
    <input class="inp" type="text" v-model="excelTitel">
    <button class="blueBtn" @click="editClicked">编辑</button>
    <button class="btn" @click="saveExcel">保存</button>
    <a href="javascript:void(0)" @click="downloadExcel">下载</a>
  </div>
  <div id="luckysheet"></div>
  <div v-show="isMaskShow" id="tip">Downloading</div>
</template>
