I also cut PVC on the table saw. I usually 2 holes drill holes near either end, one big enough for my drill's screw-driver extension and one just big enough for a drywall screw.
I can then screw the PVC to a 2x3 from Home Depot or Lowes, and then run it through with feather boards, etc just like a piece of wood.
the screw is never near the blade.

Sometimes if I'm drilling out a strip, I'll stop before the end.

I used to be nervous too but this method works pretty good. If I just need a few strips I'll hand hold a long piece and only go about half the length.

If you cut a lot, wear a good mask, PVC and ABS are probably not good to breathe in (unlike the clear health benefits of cedar and epoxy dust....)
