Many woodworkers think the table saw cuts crude and uneven edge which must be cleaned up on a jointer prior to glueing. However, this isn't always true as the glue must penetrate into the wood if it is to do its job properly, so it needs open pores. A piece of wood has passed over a jointer blade too slow or over blunt knives can compress the wood which will prevent glue penetrating.
If you use the correct technique on a table saw, you can create a straight and square surface which is slightly abraded, this is ideal for glued joints. The trick to this is mostly in the way in which you feed the board through the blade. It has to move at a constant speed without wavering.
You must ensure that you use the correct blade for this job. In my experience the triple chip blade on a relatively powerful saw is the best way to achieve clean straight jointable edges. However, be careful of cheap triple chip blades, as the quality will definitely affect your cut. A saw with a minimum of 3 hp is necessary to ensure that you get the best edge possible. This doesn't mean you cannot do it on the less powerful saws but it will be more difficult.
Your left hand should guide the board along the fence, place it on the left side of the board. Your right hand should do the pushing, always keep it on the very end of the board with a consistent forward pressure. Make sure your left foot is as far forward as possible but remain comfortable. As you push the board through the blade lean forward onto your left foot and continue the consistent pressure, this way you should only need to take one smooth step with your right foot to reach the saw and finish the cut.
I would advise you to start with a piece of scrap timber and practice until you are used to the technique, your joints will love you for it.
