If anyone is interested, I can offer a temporary solution. Add to the file vendor/phpoffice/phpword/src/PhpWord/Writer/HTML/Element/Table.php after 55 lines ($cellFgColor = null;) following code: if (strtolower($cellBgColor) === 'auto') { $cellBgColor = null; } I know it's bad practice to edit something in Vendor folder, but before this bug fixing - it can be usefull.

I know that the following line code help me to escape invalid character for docx document:

Settings::setOutputEscapingEnabled(true);

Maybe it could do the job as well for pdf. Let me know if it works.
