Hello,
Doing replacements in templates that include multiple texts, tables, lists, images... is fully tested and working.
If you send to contact[at]phpdocx.com the simplest DOCX template sample that illustrates your issue, we'll check it and generate a custom sample script using it.
Please note that placeholders to be replaced are case sensitive. Maybe the placeholder names of the table aren't correct? Please send a DOCX template sample, we'll check it.
Regards.
