There are many opinions round these parts about what you should do with a fence. Some argue for the bare minimum, a straight piece of wood clamped to the table, others very expensive precisely milled hardware that can be adjusted in a multitude of ways. And everywhere in between. Personally I fall in to the latter. I find t-track on my table and fence useful. I also like to keep things as simple as possible. I like a long tall fence but I often use "sacrificial" wood clamped to my existing fence to achieve this. Ultimately, you will have to make lots of router chips and many many many mistakes to find out what works for you. I suggest starting simple and adding things as you go. I can promise you this, your first router table will not be your last.
