Hi Bill and welcome. Most tables come with an insert plate which may or may not be drilled to fit some of the popular routers available. The 6184 model number you have implies that it may be a newer version of the 618. Good chance that it has the same bolt pattern but I don't have one of each to confirm that. It's usually not that hard to drill your own holes and if you go that way we can help steer you through it.
