Question

我的代码是从网站上复制的。

Excel::create('Filename', function($excel) {

// Set the title
$excel->setTitle('Our new awesome title');

// Chain the setters
$excel->setCreator('Maatwebsite')
      ->setCompany('Maatwebsite');

  // Call them separately
  $excel->setDescription('A demonstration to change the file properties');
})->download('xls');
