一、依赖导入

1、Vue2 + Webpack构建的

npm i xlsx
npm i xlsx-style
npm i file-saver

同时修改以下：
解决 Can’t resolve ‘./cptable’ in ‘…’ 的问题，在 vue.config.js 文件中加入该配置

module.exports = {externals: {'./cptable': 'var cptable'}
}

2、Vue3 + Vite构建的
npm i xlsx
npm i xlsx-style-vite

二、导入项目

import * as XLSX from 'xlsx'
import * as XLSX_STYLE from 'xlsx-style' // Vue2 + Webpack
import * as XLSX_STYLE from 'xlsx-style-vite' // Vue3 + Vite
import FileSaver from 'file-saver' //保存下载

三、项目示例

const exportExcel = () => {let table = [// 表格表头 ["能耗周期", '燃气消耗量(m³)', '水消耗量(m³)', "电消耗量(kwh)", "供热消耗量(m³)"]];state.tableData.forEach((item, index) => {let rowData = [];//导出内容的字段 rowData = [index + 1, item.date_month, item.zlconut, item.jscount]table.push(rowData)});let bookNew = XLSX.utils.book_new();let workSheet = XLSX.utils.aoa_to_sheet(table);XLSX.utils.book_append_sheet(bookNew, workSheet, '企业能耗统计')// 设置单元格宽度 workSheet['!cols'] = [{wpx: 80}, {wpx: 100}, {wpx: 100}, {wpx: 100}];// 导出Excel, 注意这里用到的是XLSXS对象 let wbout = XLSXS.write(bookNew, {bookType: 'xlsx',bookSST: false,type: 'binary',})FileSaver.saveAs(new Blob([s2ab(wbout)], {type: 'application/octet-stream'}),'企业能耗统计.xlsx');}const s2ab = (s) => {var buf = new ArrayBuffer(s.length)var view = new Uint8Array(buf)for (var i = 0; i != s.length; ++i) view[i] = s.charCodeAt(i) & 0xffreturn buf}
