Please help me with plurals within noun phrases.
Let's say we have a table where current states of vehicles are listed (e.g. "alarm" state, "normal state", "on the move" state, etc.).
Is it possible to call this table a "states table" (to stress that many states are displayed in it), or is only "state table" correct?
What happens if we add "vehicle" here? is it alright to say:
1. "Vehicle states table" - to suggest that there is only one vehicle whose states are in the table
2. "Vehicles states table" - to suggest that there are many vehicles in the table and each has many states.
3. "Vehicles state table" - to suggest that there are many vehicles in the table and their collective, general state is shown.

Or would "vehicle state table" be the only possible name for this thing in all cases?

More examples:
Can I say "a guitars showcase" to suggest that there are many guitars in this showcase?
Can I say "a birds habitat" to stress that there are many birds in the habitat?
What will change in the meaning if I use the possessive: "a birds' habitat"?

Thanks, Merry Christmas!

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.
thanks for your opinion!
Please tell why you use "states" in plural in "vehicles' states table", but use the singular in "vehicle state table"?

Regarding the "a birds' habitat" example - can the article be thought of as modifying "habitat", not "birds'"? (so "a birds' habitat" = "a habitat of birds"?)

And what about a list of vehicles?
Would it be "vehicles list" or "vehicle list"?

I would be very grateful if someone could give me some general rules for this kind of problems (or "these kinds of problems"? Emotion: smile)
Max Fedoseevsome general rules
In 99.9% of cases when a noun modifies another noun, the first (i.e., the modifying) noun is in the singular.

state table
vehicle list

It doesn't matter how many coats you hang on it, it's still a coat rack.
It doesn't matter how many guitars you display in it, it's still a guitar showcase.
It doesn't matter how many books you put on it, it's still a book shelf.
It doesn't matter how many ...

Well, you get the picture.

Students: Are you brave enough to let our tutors analyse your pronunciation?
Thanks CJ! That is convenient Emotion: smile Can you think of any examples out of that 0.01% left?

Is that also true if we have different kind of modifiers that don't tell us about the purpose/type of the last noun?

For example:
vehicle list(s) review (meaning the review of all the lists of vehicles)
vehicle(s) price (meaning the overall price of all the vehicles)
