vue3里将table表格中的数据导出为excel

想要实现前端对表格中的数据进行导出，这里推荐使用xlsx这个依赖库实现。

1、安装

pnpm install xlsx

2、使用

import * as XLSX from "xlsx";

直接在组件里导入XLSX库，然后给表格table通过ref创建响应式数据拿到table实例，将实例传给XLSX.utils.table_to_book()方法，再使用XLSX.writeFile()就可以下载excel文件了。具体方法请看demo源代码。

3、demo源代码

<template><div class="page6"><div style="display:flex;justify-content: flex-end"><el-button type="primary" @click="exportExcel">导出</el-button></div><el-table ref="tableRef" :data="tableData" stripe style="width: 100%"><el-table-column prop="date" label="Date" width="180" /><el-table-column prop="name" label="Name" width="180" /><el-table-column prop="address" label="Address" /></el-table></div>
</template><script setup>
import * as XLSX from 'xlsx'
const tableRef = ref(null)
const exportExcel = () =>{const tableDom = tableRef.value?.$el;if (tableDom) {const wb = XLSX.utils.table_to_book(tableDom);XLSX.writeFile(wb, '表格数据.xlsx');}}
const tableData = [{date: '2016-05-03',name: 'Tom',address: 'No. 189, Grove St, Los Angeles',},{date: '2016-05-02',name: 'Tom',address: 'No. 189, Grove St, Los Angeles',},{date: '2016-05-04',name: 'Tom',address: 'No. 189, Grove St, Los Angeles',},{date: '2016-05-01',name: 'Tom',address: 'No. 189, Grove St, Los Angeles',},
]
</script><style lang="less" scoped>
.page6{width: 100%;height: 100%;padding: 20px;
}</style>
