需求背景

原使用 vue3-json-excel ，导致在笔记本office环境下，出现兼容性问题

 <vue3-json-excel class="export-btn" :fetch="excelGetList" :fields="jsonFields" header="告警配置列表" name="告警配置列表.xls" type="xls"><span>批量导出</span></vue3-json-excel>

生成的.xls文件，提示文件格式和扩展名不匹配，文件可能已损坏或不安全
生成的.xlsx文件，提示文件格式或文件扩展名无效

解决思路

既然 vue3-json-excel 达不到效果，就改用xlsx

解决效果

将json导出为excel

导出样式

应粉丝要求，附上导出样式

import {h} from "vue";
import {ElMessageBox} from "element-plus";ElMessageBox({title: '导出Excel表格',draggable: true,showCancelButton: true,showConfirmButton: false,message: h('div', null, [ // 这里用到了h函数h(ElButton, { text: true, type: 'primary', innerHTML: '导出选中数据', onClick: assignExport }),h(ElButton, { text: true, type: 'success', innerHTML: '导出所有数据', onClick: allExport })]),cancelButtonText: '取消',
})
// 导出
const assignExport = () =>{console.log(111)
}
const allExport = () =>{console.log(222)
}
