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）

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" /><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>

• 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><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><a href="javascript:void(0)" @click="downloadExcel">Download source xlsx file</a></div><div id="luckysheet"></div><div v-show="isMaskShow" id="tip">Downloading</div>
