How to color a "cell"?

[Richard Gaskin]

I need to set the backgroundColor of a complete "cell", where "cell" is
defined as the portion of a row in a table field between tabs when the
vGrid is set.

I had hoped the paragraph-level formatting options introduced in v5.x 
would help, but alas as far as I can tell I can only set the 
backgroundColor of a run of text, not the full cell.

Anyone know a way to do this WITH FIELD/TEXT PROPERTIES ONLY?

(Pardon the all-caps, but I can come up with many workarounds that 
include other objects, but I really need something here that works with 
one field object and nothing else.)
