No styling when converting DOCX into PDF

I am trying to convert a DOCX file to PDF with PHPWord. When I execute the script it looks like that some style elements are not converted. In the DOCX file I have one image, two tables with border 1px and hidden borders and I am using Tabs.

When I execute the script I get a PDF file without the image, all the Tabs are replaced with Space and all the tables have a border 3px.

Does someone know why I am missing these styles?

Here is my script:

while ($data2 = mysql_fetch_array($rsSql)){
  $countLines=$countLines+1;
  $templateProcessor->setValue('quantity#'.$countLines, $data2['quantity']);
  $templateProcessor->setValue('name#'.$countLines, $data2['name']);
  $templateProcessor->setValue('price#'.$countLines, "€ " .$data2['price'] ."");
}

\PhpOffice\PhpWord\Settings::setPdfRenderer('./dompdf');
\PhpOffice\PhpWord\Settings::setPdfRendererPath('./dompdf');
\PhpOffice\PhpWord\Settings::setPdfRendererName('DOMPDF');

$temp_file = tempnam(sys_get_temp_dir(), 'Word');
\$templateProcessor->saveAS($temp_file);

$phpWord = \PhpOffice\PhpWord\IOFactory::load($temp_file); 

$xmlWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord , 'PDF');
$xmlWriter->save('result.pdf');  

header("Content-type:application/pdf");
header("Content-Disposition:attachment;filename='result.pdf'");
readfile("result.pdf");
