I've tried to create a table into an existing file using this code.
$docx = new CreateDocxFromTemplate($input_file);
...
$docx->addTable(
   array(array('Title A','Title B','Title C'),array('First row A','First row B','First row C'),array('Second row A','Second row B','Second row C')),
   array('tableStyle' => 'LightListAccent1PHPDOCX', 'columnWidths' => array(1800, 1800, 1800))
);
The resulting table have no style (no borders, no fonts, black color).
I've tryed also other styles found with parseStyles method with no success.
If I create a custom style, and use it in the table, it works in the existing docx file...
