1. This is the boy who Jane likes.
2. This is the boy whom/that Jane likes.

#2 is grammatical, but what about #1? Can we use 'who' in Sentence 1?
============================
3. Look at the table that/which is made of stone.
4. Look at the table whose color is pink.
5. Look at the table of which the color is pink.
6. Look at the table the color of which is pink.

Are they all grammatical among #4 and #6?
1 is used casually, but as you noted is not correct grammatically. In 2, I'd most likely use "that."
3 -- that
4 -- OK
5 -- No
6 -- Very clumsy
