Hi, thank you for your post into the forum.
Sadly, SQL Doc does not allow you to be able to include or exclude columns from tables or views for any given table before the generation of the document.
Therefore I submitted a Feature Request on your behalf, the reference number for this request is SDOC-1500. I cannot guarantee that this request will be successful, or if approval is given what future version of SQL Doc it will appear in.
Thank you for your suggestion.
