Hi Janecki,
you could do this with only free tools (google docs) but you need to be able to somewhat understand html.
This is a quick sketch, let me know if you need a more detailed instruction.
- Create your template with google docs, including one row of the positions table
- save/export as html
- open with browser and view the source code
- find the table portion of the row you want to loop and copy it into a „text aggregator“ module
- map to the source module so it creates the looped rows section
- map this output to a „compose a string“ module which holds the rest of the html
- use „create a document“ from Google docs to create ur document from that html.
Hope this helps!
John
