Okay, which is what I mean by "compact". There'd be some lowest value
and some highest value, and the table has that many entries in it,
regardless of how many of them actually have meaningful information in
them.

With a hashtable, the values can be sparse. They would, however, still
need to be constant; otherwise it'd be hard to build the table in
advance.
