vue3导出excel表格

可以使用第三方库`exceljs`来进行导出：

1. 安装依赖库：`npm install exceljs --save`

2. 引入库和样式：

   import * as Excel from 'exceljs';
   import 'exceljs/dist/exceljs.min.css';

3. 编写导出方法：

   exportExcel() {
     const workbook = new Excel.Workbook();
     const sheet = workbook.addWorksheet('Sheet Name');
     const title = ['列1', '列2', '列3'];
     sheet.addRow(title);
     const rows = [
       [1, 2, 3],
       [4, 5, 6],
       [7, 8, 9]
     ];
     rows.forEach((row) => {
       sheet.addRow(row);
     });
     workbook.xlsx.writeBuffer().then((buffer) => {
       const blob = new Blob([buffer], {type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'});
       const fileName = 'export.xlsx';
       const link = document.createElement('a');
       link.href = window.URL.createObjectURL(blob);
       link.download = fileName;
       link.click();
     });
   }

4. 在页面中调用导出方法：`<button @click="exportExcel()">导出Excel</button>`

希望能对你有所帮助~
