Hello,
If you call load a template and then call addTable, the table is added after all existing contents.
You can add WordFragments in the template after or before any existing content:

Or replace a placeholder by a WordFragment:

This WordFragment can be a table, a list, a paragraph, an image... almost any Word content.
Regards.
