import * as XLSX from 'xlsx'

3.使用(核心代码)

<template>
    <div class="index">
        <el-button type="primary" @click="save">导出</el-button><!-- 导出按钮 -->
        <!-- 表格组件 -->
        <el-table :data="tableData" style="width: 100%" border id="el-table" ref="tableRef">
            <el-table-column type="selection" width="50" align="center" />
            <el-table-column label="姓名" prop="name" />
            <el-table-column label="性别" prop="age" width="180" />
            <el-table-column label="电话" prop="phone" width="180" />
            <el-table-column label="电子邮件" prop="email" width="180" />
            <el-table-column label="介绍" prop="introduce" width="260" />
        </el-table>
    </div>
</template>
<script setup lang="ts">
// 依赖引入
import FileSaver from "file-saver";
import * as XLSX from 'xlsx'




function save() {
    nextTick(function () {
        let filename = ''
        const xlsxParam = { raw: true } //转化成Excel使用原始格式
        const elTable = XLSX.utils.table_to_book(document.getElementById('el-table'), xlsxParam)
         filename = '导出测试.xlsx'
        const wbout = XLSX.write(elTable, { bookType: 'xlsx', bookSST: true, type: 'array' })
        try {
            FileSaver.saveAs(new Blob([wbout], { type: 'application/octet-stream' }), filename)
        } catch (e) {
            if (typeof console !== 'undefined') {
                console.log(e, wbout)
            }
        }
        return wbout
    })
}
</script>
