Yeah, it's kinda like the term "tavern table" here in the states. Most all 18th century homes in colonial America had one or more of these small, portable tables however, I doubt that's what they called them back in the day. Ditto "bible box", another generic term for small wooden boxes made in 17th & 18th century america, no way people called them "bible box" then as books were hideously expensive and very few folks could afford a book.
