In my case, yes, that's in a style file... reason allowing me to forget to
mention the makeatletter thingie.

You cannot reproduce it, because I misplaced the call to mykeewithnextpar: it
must be between the two things you want to see glue'd together.

Hence, in the example you mention, it works perfectly.

For answering the OP's question, the call must be moved between the DEPARTMENT
title and the table...
