使用PhpSpreadsheet导出Excel文件

最近接到个新需求：导出一个包含多个sheet的Excel文件。

本打算用PHPExcel，然后查了一下 发现PHPExcel已经不再维护，PhpSpreadsheet是PHPExcel的下一个版本，那么暂时就用它实现新需求吧。

实现代码：

<?php

namespace frontend\controllers;

use Yii;
use yii\web\Controller;
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\IOFactory;
use PhpOffice\PhpSpreadsheet\Style\Border;

/**
 * 导出Excel
 */
class ExcelController extends Controller
{
    public function actionIndex()
    {
        $data = [
            ['title_A' => 'A', 'title_B' => 'B', 'title_C' => 'C', 'title_D' => 'D', 'title_E' => 'E', 'title_F' => 'F', 'title_G' => 'G'],
            ['title_A' => 'A1', 'title_B' => 'B1', 'title_C' => 'C1', 'title_D' => 'D1', 'title_E' => 'E1', 'title_F' => 'F1', 'title_G' => 'G1'],
            ['title_A' => 'A2', 'title_B' => 'B2', 'title_C' => 'C2', 'title_D' => 'D2', 'title_E' => 'E2', 'title_F' => 'F2', 'title_G' => 'G2'],
        ];
        $data2 = [
            ['title_A' => 'A', 'title_B' => 'B', 'title_C' => 'C', 'title_D' => 'D', 'title_E' => 'E', 'title_F' => 'F', 'title_G' => 'G'],

            ['title_A' => 'A2', 'title_B' => 'B2', 'title_C' => 'C2', 'title_D' => 'D2', 'title_E' => 'E2', 'title_F' => 'F2', 'title_G' => 'G2'],
