Trust me, I know all about change. Those pictures were from 6 months ago - a few things have already changed on the bench. Over the Christmas break some more things will change as well, namely additional shelving below the bench and probably some permanent shelving above it to go with what I already have.
Your reloading bench is always going to change. No doubt about that. I'd steer clear of folding type tables though - they are not designed for that type of use and just about always have significant movement in them.
Think about it, plan it, draw it up, then build something permanent with the knowledge that it will never be perfect and always need a tweak.
