IMHO 100% definately. I made a jig for that very thing cutting box joints on my TS. Don't know if I still have it, but what it entails is making a key which each successive joint slides on and so the spacing is perfect.. . . . . . . Would doing it with a Dado Blade on my tablesaw be easier. . . . . .
Yes you can do it with a router table too but I like the cut a TS gives better for this purpose and it is faster because with a RT you have to go a little slower to prevent tearfout on softer woods.
