打印dompdf时PDF容易破解

Question

嗨，我正在使用dompdf从HTML生成pdf，但无法理解为什么在打印pdf时会损坏

这是我的功能

public function printRunsheetBymanifestAction()
{
    $manifestId = $this->params()->fromRoute('id', 0);
    $getDetails = $this->getDeliveryTable()->getRunSheetData(array('manifestId' => base64_decode($manifestId)));
    $getItemDetails = $this->getManifestTable()->getManifestItemsById($getDetails[0]['manifestId']);
    $options = new Options();
    $options->set('isRemoteEnabled', true);
    $options->set('defaultFont','Courier');
    $options->set('defaultPaperSize','A4');
    $domPdf = new \Dompdf\Dompdf($options);
    $domPdf->set_option('isHtml5ParserEnabled', true);
    $view = $this->getServiceLocator()->get('ViewRenderer');
    $viewModel = new ViewModel();
    $viewModel->setTemplate('delivery/index/print-runsheet-bymanifest.phtml');
    $viewModel->setVariable('results', $getDetails);
    $viewModel->setVariable('itemDetails', $getItemDetails);
    $content = $view->render($viewModel); //make html content for loadn in doampdf
    $domPdf->loadHtml($content);
    $domPdf->render();
    $fileName = $getDetails[0]['runsheetNumber'].'_'.date('d_m_Y');
    $domPdf->stream($fileName,array("Attachment"=>1));
    exit;
}

这是我的phtml模板，即使我尝试使用分页符CSS在所需的输出后分页也是如此

<?php $results = $this->results;
$items = $this->itemDetails;
?>
<style>
table.body {
                width: 100%;
               margin: 0 auto;
            }
td.text-right{text-align: right;}
td.text-center{text-align: center;}
.page_breack{
    clear: both;
    page-break-after: always;
}
</style>
<table class="body" align="center" style="border-top: 1px solid #333; border-left: 1px solid #333; border-right: 1px solid #333;">
