效果如图↓
一级导出：↓
二级导出：如下图
三级导出：↓
Export2Excel.js Blob.js 等
安装依赖
npm install -S file-saver
npm install --save xlsx@0.10.0
npm install -D script-loader
npm install xlsx-style --save 其中xlsx-style 有坑↓
在vue.config.js中配置↓
const { defineConfig } = require('@vue/cli-service')
module.exports = defineConfig({
transpileDependencies: true,
configureWebpack:{
externals: {
'./cptable': 'var cptable',
},
resolve: { fallback: { fs: false } }
}
})
（node_modules\xlsx-style\xlsx.js ）
将
if(typeof jszip === 'undefined') jszip = require('./js'+'zip').JSZip;
替换成
if(typeof jszip === 'undefined') jszip = require('./jszip.js');项目结构↓
注：
其中Export2ExcelPro.js 是可以导出二级标题， Export2Excel.js是导入一级标题
excelExport.js是封装了调用方法。

const header = ["日期", "姓名", "其他", "", ""]; //表头第一行
const multiHeader2 = ["", "", "个人", "", "家庭"];//表头第二行
const multiHeader = ["", "中文名", "年龄", "性别", "地址"]; //表头第三行
const filterVal = ["date", "name", "age", "sex", "address"];//对应字段
// 这里要注意 header 和 filterVal 的数组长度一定要相等，否则会报错
const merges = ["A1:A3", "B1:B2", "C1:E1", "C2:D2"];//从左到右存放横跨两个单元格的记录
一一对应去理解
