How do I repaint my coffee table?

I live in an apartment, no yard or anything and I have this gigantic vintage coffee table thats is wood with a clear finish over it (the finish is pretty much wasted away) I found this coffee table next to a dumpster one day and its a great table but all my furniture is black so it doesn't match and I wanted to paint it black but I don't know how to do this...do I need to sand it? Can I spray paint it? Where would I do it at since I have no yard??? This thing is very heavy and hard to lug around. Help!
