Not so sure you'd want to cut angled slots on the table - assuming you mean slots that are not at 90 degrees to the material surface. If so, there was an article on making an angled tower a month or so ago - I think in Popular Woodworking - I'll look for it and post it when I find it - should be this evening - but they were doing exactly what you're asking about using an angled jig that the router base would ride on to cut those angled slots or rabbits. They also cut angled mortises, tongues and through mortises - all at 3 degree cut angles - with handheld router and jig set-up.
