1、安装插件
npm install file-saver --save npm install xlsx --save
2、使用（方法二只用安装 xlsx 就可以导出数据）
方法一：
<template> <div> <el-button size="mini" class="none-radius" @click="handleExport">导出</el-button> <el-table id="exportTable" :data="tableData" style="width: 100%"> <el-table-column prop="userName" label="姓名" width="150" align="center" :show-overflow-tooltip="true"></el-table-column> <el-table-column prop="sex" label="性别" width="70" align="center" :show-overflow-tooltip="true"> <template slot-scope="scope">{{scope.row.sex | sexList}}</template> </el-table-column> ... </el-table> </div> </template> <script> import FileSaver from 'file-saver' import XLSX from 'xlsx' export default { methods() { handleExport() { this.$confirm('该操作将导出所有列表数据，是否继续？', '提示', { confirmButtonText: '确定', cancelButtonText: '取消', type: 'warning' }).then(() => { let exportTable = XLSX.utils.table_to_book(document.querySelector('#exportTable')) let exportTableOut = XLSX.write(exportTable, { bookType: 'xlsx', bookSST: true, type: 'array' }) try { FileSaver.saveAs(new Blob([exportTableOut], { type: 'application/octet-stream' }), '表格名称.xlsx') } catch (e) { if (typeof console !== 'undefined') console.log(e, exportTableOut) } return exportTableOut; }).catch(() => { }); }, } }
方法二：
<template> <div> <el-button size="mini" class="none-radius" @click="handleExport">导出</el-button> <el-table id="exportTable" :data="tableData" style="width: 100%"> <el-table-column prop="userName" label="姓名" width="150" align="center" :show-overflow-tooltip="true"></el-table-column> <el-table-column prop="sex" label="性别" width="70" align="center" :show-overflow-tooltip="true"> <template slot-scope="scope">{{scope.row.sex | sexList}}</template> </el-table-column> ... </el-table> </div> </template> <script> import XLSX from 'xlsx' export default { methods: { handleExport() { this.$confirm('该操作将导出选中的列表数据，是否继续', '提示', { confirmButtonText: '确定', cancelButtonText: '取消', type: 'warning' }).then(() => { //导出 let table = document.getElementById('exportTable'); let worksheet = XLSX.utils.table_to_sheet(table); let workbook = XLSX.utils.book_new(); XLSX.utils.book_append_sheet(workbook, worksheet, 'sheet'); try { XLSX.writeFile(workbook, '文档ll.xlsx'); } catch (e) { console.log(e, workbook); } }).catch(() => { }); }, } }
