As I am a woodworker with very limited tools, I would assume that you have at least a hand held router, so first build the router table, side runners at least a foot longer than the proposed table top and 1/4" to 1/2" taller than your thickest board/slab, then mount your runners to the base (a sheet of chip board, Masonite, particle board, plywood etc.) spacing the runners far enough apart to allow the widest board/slab to fit between then you construct the router sled to  slide up and down the runners and the router across the slab that way you can get a level slab, also could use the same method to square the edges by using taller runners and clamping the slab/board to the squared runner.  A lap joint could be cut using the router sled also.  
I have used my 4x24 Bosch belt sander on large slab type surfaces to maintain thickness rather than one of my several routers. I've even used radial arm saws, many times in fact, to create a true flat surface. 
A hand plane was the tool I was forced to joint edges with in 7th grade, like many kids, it was hand tools or nothing which is the best beginning and perhaps the more creative end as well. Lots, meaning "too many of tools", is a disease many folks get, while ignoring technique. I'm not limited but i try to avoid wasting space and moolah.

he (OP) may have been curious and after posting but then forgot his password.  but he did get a pic in the thread, which is a learning curve for many.  he also may think no one will reply, at for some time.  Our forum tends to be quick to try to help new members.

I really like seeing what you guys produce from the slabs. I saw and dry. When people send me pictures or I see what a finnished product from my work, my comment is ussually. I didn't Charge Enough. The wood looks better finished than it did when I opened that log.

Joining boards end to end isn't done much.  Generally doesn't look very good, but one way to make it look good and work would be to use a strip of wood between them (grain running perpendicular to the slabs).  This strip could be straight or S shaped or curved.  you then use kreg jig screws to to screw the two halves of the top to the divider strip.  Depending on the thickness, you'll have to see how strong and rigid it is.  It may be necessary to add reinforcement on the underside.  You could add a routered in metal plate, or maybe bowties?  

Keep in mind this assumes you glue up each half first at the parallel grain glue joint.  What I'm talking about above is joining the end grain to a divider strip.  The strip can be a contrasting wood like Walnut, Ebony, purple heart etc. or it could be the same type of oak.
Anything someone can design, I can sure figure out how to fix!
If I say it\\\\\\\'s going to take so long, multiply that by at least 3!

It could be done as you say by making the center strip similar to a breadboard end design which allows for wood movement. No Kreg crews required perhaps if a frame surround the affair which also allowed for wood movement. 
Seems to me the OP's wood belonged as other table parts and he needed a few top suited ones as the better solution.

Yes Kentuckid is correct, you could do a breadboard divider. That is sort of the next level of woodworking. I was trying to keep it a little simpler as the OP is a beginning woodworker.
