我正在尝试借助 PHPSpreadsheet 将 Excel 文件直接转换为 PDF。但出现错误“找不到类'Mpdf\Mpdf' ”，这是我的代码：

<?php 
  require 'vendor/autoload.php';
  use PhpOffice\PhpSpreadsheet\IOFactory;
  use PhpOffice\PhpSpreadsheet\Worksheet\PageSetup;
  use PhpOffice\PhpSpreadsheet\Reader\Xlsx;
  use PhpOffice\PhpSpreadsheet\Writer\Pdf\Mpdf;

  $reader = new \PhpOffice\PhpSpreadsheet\Reader\Xlsx();
  $reader->setReadDataOnly(true);
  $spreadsheet = $reader->load("excel.xlsx");


  // when I use this MPDF class, I'm getting an error Class \Mpdf\Mpdf not found

  $writer = new \PhpOffice\PhpSpreadsheet\Writer\Pdf\Mpdf($spreadsheet);
  $writer->save("excel.pdf");

请帮助上面的代码。

谢谢
