You don't need a table for a simple sine oscillator. You just compute sin(a) and cos(a) on note-on, and that's it. You don't store the output in a table, you just apply that 2x2 matrix every time. Tables can definitely have their place, depending on your synthesis method. If you want something like pitch bend, going for a sine table may very well be the fastest (it depends a bit on how much cache you want to burn).
