Unless you have severe space limitations I suggest you build your router table separate from your saw. You will find that making adjustments to the router in a saw table is more difficult and time consuming than on a free standing unit. You can build a table with the features you deem best easily. I highly recommend the tables from Shopnotes #1 and Oak Park, the home of The Router Workshop. Having built both I can tell you they perform well.
