Dono is used together with a noun, and dore is used on it's own.

どのテーブルですか
【どの】->【テーブル】【です】【か】

The easiest translation is "which table is it?" but if you mean "which is the table [you're referring to]?" like when you're asking someone which table is the correct table then that's acceptable.

Otherwise, it's "which table is it?" as どの is referring to テーブル only and not anything else.

That would be "あのテーブルはどれですか。" in Japanese.

if you are a waiter and ask your friends, which table to order earlier is very suitable if using:"どのテーブルですか？"

It can be implied: "Which table is my table?" = "私のテーブルはどのテーブルですか"

Because the topic of the sentence is not mentioned, there is no は.

as far as my understanding goes, you don't use は withこの/その/どの and withこれ/それ/どれ　

No, this would be 「テーブルはどこですか？」.

No, because どっち (not どち) acts the same way as どれ except it usually means "which (of two choices)", so you can say どっちのテーブル (just like どれのテーブル, which becomes shortened to どのテーブル). It is more casual than どれ though.

"Whose" would be だれの, and the subject is "this", so the sentence would be これはだれのテーブルですか？

Well, Duo hasn't taught us many other verbs yet, and です is the equivalent to "is/am/are"; how often do you see them in basic English sentences?

Because God wants it.

I was wondering the same thing. Anybody?

if you are a waiter and ask your friends, which table to order earlier is very suitable if using:"どのテーブルですか？"

and if you use:「テーブルはどこですか？」it means : "where is the table?" cause THE TABLE IS USING は.

You're at an event with assigned seating. You group is at table five. You have to find the correct table.

Your friend is moving house and you've offered to help. When you arrive, they ask you to help move a table out of the truck. They own several tables.
