"A good table for poker" is just that. The table will have slots for chips (for betting) and usually a place to put a drink for each player (usually four). An ideal table has eight sides, although a four-sided table can also be good. Generally, a good mah jhong table will be suitable for poker just because of the size for a four-person game. The quote might be incorrect and supposed to be "a good poker face." Someone who has a good poker face is a person who can hide their emotions and not betray a very good or bad poker hand by the look on their face and can disguise their feelings well.
