The clips may be a bit difficult to install if you have already assembled the base since I usually cut the slots with a router or table saw prior to assembling. I found these easy to use and very effective in holding the top to the base while still allowing expansion and contraction. The other suggestions will work also, but I would definitely allow for expansion and contraction in some way or, over time, something is likely to give; most likely the top.
