For some of the selectors in tables, we don't have a refactored slot for these.  So, for .table-caption, I just have allowed the necessary properties here until a slot home in precalc is arrived at.  I didn't want to work across branches while precalc refactoring is in play.  I will add a Trello card for this one as well and we can horizontally fix this.  This type of thing is like the .glossary issues.  Just a feature that's used in every book, but little pieces are invoked and styled as needed across books.
