I agree with both of Bas's comments. Track saw is safer and would be pretty easy to use for this but you may want to make what I call a track setting jig. Something to position the track 1.5 inches plus the saw kerf from the good edge of the stock. You will also want to put other wood of the same thickness under the track when the workpiece is narrower than the track.
On the table saw, a feather board would help you consistently keep the workpiece tight to the fence but it would pretty much require you to get the boards to the same width before you start cutting. A ripping blade would be a good idea too but just to reduce saw effort.
I also congratulate you for doing this the way you are - making all the parts as you go. That should be less total effort. The one time I made a whole kitchen I did it a cabinet at a time. I was using the front of the car garage so I did not have much space without backing the cars out. But an equally important reason was my strong tendency to get bored with too much effort before the payoff of a completed project. I made a cabinet at a time where I could. I had a run of base that supported the sink and housed the dishwasher that I saved until last. I think that also helped my wife's confidence. She had a bunch of completed cabinets installed at the time I took her sink out of service.
