How do we know when to use an ICE table?

You would use ICE when the question gives you the initial concentration of the reactants and/or products, to later solve for the concentrations of the products or reactant when the the reaction is at equilibrium.

ICE tables are often used when you are given some initial molar concentrations of specific molecules. If the question is asking for the equilibrium molar concentration, you can use ICE to find it. Additionally, you can use it on order to find the composition of equilibrium mixtures.
For later methods within acids and bases, you can even use ICE to find out the pH and percentage ionization of specific weak acids or bases.

ICE is also generally used for weak acids and bases. With strong acids and bases, you can assume full protonation/deprotonation and assume that the concentration of the original strong acid or base becomes 0 and the concentration of the products is equal to the intitial acid/base concentration.
