我尝试过dompdf，但没有运气！
我正在使用laravel 5的刀片模板引擎，我想转换使用刀片模板引擎创建的html文件。
我使用了dompdf，使用刀片语法测试它，但它会抛出错误。但是当我在其中输入普通的html页面时，它可以正常工作并将html代码转换为pdf。
请建议我任何与刀片兼容的html到pdf转换器！
请帮助伙伴：）

这是我的php刀片视图文件，将以pdf格式下载。
pdf转换如下
$html = App::make('dompdf.wrapper');
$html = $html->loadHtml(view('cards.pdf_card',compact('data'))->render());
return $html->download('card.pdf');
此处的'数据'被认为是之前生成的。
错误如下，
ErrorException in frame.cls.php line 765:
Argument 1 passed to DOMNode::appendChild() must be an instance of DOMNode, null given, called in /opt/lampp/htdocs/brt_praja/vendor/dompdf/dompdf/include/table_frame_decorator.cls.php on line 312 and defined
提前感谢您的帮助。
