Tables are a fine way to explore the testable state space of moderately complex functions where there's natural or explicit discrete points in each dimension / argument. It's easy to see which combination is or isn't tested when it's in a tabular form, vs almost any other approach.

For actually driving logic, it tends to be somewhat user unfriendly unless there's something intrinsically table-oriented in the domain. The best table-oriented program I ever worked with was a disassembler; naturally, machine code (particularly the x86 series) lends itself to tables since unused / reserved opcodes in one generation turn into prefixes in the next.

Tables do make explicit the entire state space, though, and if followed to the logical cross-product extreme, are agnostic to the hierarchy imposed by OOP. But the geometric space explosion of cross-products makes you want to create new abstractions to cover more ground, and you start to lose what tables gave you to begin with.
