Proper: "Vehicle state table" Another (and better) option: "State of vehicle table" Also: "Vehicles' states table" because the "state" is a possessive of "vehicle" Singular (as in the first option on top) is always best: "a guitar show", "a bird habitat" When discussing a particular bird's or guitar's show then "a bird's habitat". To say "a birds' habitat" is wrong because "a" denotes a singular possessive noun; whereas, "birds'" is a plural possessive noun.
