First you need to understand what a tight poker table is. Tight players are those who only play a few hands before the flop. When they play what they have they will usually raise since you can count that they have strong cards. They also rarely easily give up when they play what they have since they have waited for a while for a good hand.
Tight players still have different styles of play but it is safe to assume that when they play their cards, it is often based on solid values. Remember that you need some good cards on your hand if you want to call the raise of a tight player. Another safe assumption will be that they will bet out on different flops or hold back when they get a scare card.
When playing against tight players you need to remember that you should know the risk when calling a raise from someone you read as a tight player but be willing to push for a raise yourself. Tight players will most likely re-raise you and push you off when they got monster cards but they also have a tendency to fold when they feel your strength.
It will be easier to read tight over loose players but it does not follow that you will rake in more chips when you play against them.
You also have to consider your position when playing at kind of tight tables. You need to look at how you are positioned from the dealer button and from the pre-flop raiser. Late position somehow gives you an advantage of stealing blinds against your opponents.
Also remember that sitting on the immediate left of a preflop raiser can give you some problems. Early position raises can make you vulnerable to the strong plays of the other opponents who have yet to make a move and since you are playing a tight table, your opponents will most like play it strong for their starting hands when they got good cards.
