I assume by wavey you mean it's been intentionaly cut with some type of wavey edge in one direction and you're wanting to put a roundover, cove or ogee type edge along that wave - In the table I'd remove my fence, and use a bit with a top bearing to follow that edge - if you're trying to roundover the full thickness of the piece, then I'd make a template that exactly duplicates that edge, double sided tape it on top and let the bearing follow that. Practice on some scrap first to get the feel of it if you've never done this before.
