Hello,
We recommend you to create a table with a placeholder foreach column and use the method replaceTableVariable (http://www.phpdocx.com/api-documentation/templates/replace-table-variable-Word-document) to add as many values as needed.
To attach a page after other you can use the MultiMerge class: mergeDocx (http://www.phpdocx.com/api-documentation/docxutilities/merge-Word-documents-with-PHP).
Regards.
