Using this question as an example: Copper(II) sulphate is added to sodium hydroxide, write a balanced equation, if no reaction, write "no reaction" ... i know how to answer the question, but have forgotten how to do that table to predict the products of those two reactants

The table goes like:
........XX XX
XX
XX
with the four gaps being the potential products ... can anyone remind me how to do this? Sorry if thats confusing, I'm not sure how to explain it better :S I appreciate the help though.
