excel表格在线编辑（开源版）

前言

本文记录好用的开源在线表格
具体如图显示

另外记录下更名后的univer~，如下图（有兴趣可自行详细了解）
univer

• 在线思维导图
  

一、Luckysheet

参考gitee
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。

vue3+vite 例子

vue3+vite

• 引入样式及脚本

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

• 安装所需依赖（exceljs、file-saver和luckyexcel）

npm i exceljs file-saver luckyexcel -S

• 新建 components/excel.vue

<template>
  <div style="position: absolute; top: 0">
    <input id="uploadBtn" type="file" @change="loadExcel" />

    <span>Or Load remote xlsx file:</span>

      <option disabled value="">Choose</option>
      <option v-for="option in options" :key="option.text" :value="option.value">
        {{ option.text }}
      </option>
    </select>

    <a href="javascript:void(0)" @click="downloadExcel">Download source xlsx file</a>
  </div>
