Hello,
Thanks for sending the requested documents. We have checked them and the problem is that LibreOffice needs a character style (rStyle) when the link is truncated in a cell table.
If you are using addLink (standalone or add as a WordFragment) you can set a character style (w:rStyle, such as DefaultParagraphFontPHPDOCX included in phpdocx or a custom one using createCharacterStyle) running:
$linkOptions = array(
'url'=> 'http://www.google.es',
'rStyle' => 'DefaultParagraphFontPHPDOCX'
);
$docx->addLink('Link with a custom character style', $linkOptions);
Adding a custom character style to the link, the hyperlink will appear correctly when transforming the DOCX to PDF a truncate text inside a cell table. HTML to DOCX also allows setting a custom character style to contents.
Regards.
