I believe the main difference is the first craft bench on the first island you simply "put it in place" with a couple of bits of wood. And this one is stationary and cannot be moved/taken with you. The second craft bench you have to completely make yourself on the second island, and this can be put in your inventory and taken away with you.
when you first arrive you need to pick up 1 drift wood and walk over to the two standing up rocks and press make crafting bench. then after completing some goals you unlock bamboo crafting bench.
First, you don't need to ask on here, just check the wiki. I will answer your question anyway.
