Angular纯前端实现table表格导出

项目中使用到，记录一下简单的demo

1、安装filesaver

npm install file-saver --save

2、导出方法

import { saveAs } from "file-saver";

//方法
exportTable() {
  const blob = new Blob([document.getElementById('exportableTable').innerHTML], {
    type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=utf-8"
  });
  saveAs(blob, 'test.xls');
}

3、html

<button mat-raised-button color="primary" (click)="exportTable()">导出</button>
<div id="exportableTable" class="hidden-table">
<table>
  <thead>
  <tr>
    <th *ngFor="let item of tableTitle">{{item}}</th>
  </tr>
  </thead>
  <tbody>
  <tr *ngFor="let item of tableData">
    <td *ngFor="let title of titleArr">{{item[title]}}</td>
  </tr>
  </tbody>
</table>
</div>
