What to do with this solid Teak table?  

Odd. Very odd.
Has it been repaired right to allow for wood movement. I don't really understand that perpendicular to-the-grain board underneath with a screw in the end of it, but it looks very questionable from a wood movement standpoint.
I guess I've seen too many very bad repairs on solid wood furniture. The Aasbjerg solid teak dresser I just repaired had had one of the drawer slides glued onto the side of the case. I believe that must have happened recently, as it would have really screwed the piece up if the wood had been allowed to try to move with a board glued there to resist it. And I fixed a couple of solid teak Hvidt & Mølgaard tables once that had had oak board screwed onto the undersides, cross grain, in a misguided attempt to strengthen them. The tops had bowed a good couple inches out of flat and then had split through the middle to release the strain.
But back to the table at hand: I really don't like the weird shape. I think it might look perfectly nice as a circle?

Thanks for the quick response, leif... it is in two pieces at the moment. Attachment hardware to allow for movement is the plan. The original configuration was confusing, yeah... I ended up asking the dude a ton of questions about it, because it all seemed so strange. My first thought was to, yeah, trim the corners off of it. Still a decent option, but for the fact that I don't really need such a table. Have to admit that my primary interest was the wood. But I don't want to like, defile something nice, you know. I'm having trouble staring at the angles and imagining a round top, but it probably would look nice. More clean, anyway.
Is it possible that this isn't as old as I imagine? If the base didn't feature the angled supports for screws, I might imagine that the legs and apron belonged to something else, and somebody with some spare wood just made a new top. But I don't know. I'm new to a lot of this, and my imagination takes me places.
The shape is just kinda... dumb. Unless it's supposed to be a poker table. Hmmm.

Lots of things are possible. How about some photos of the underside?

We just got back from the trip a few hours ago. It's still in my truck. When I put it in storage, I'll inspect a bit closer and try to take better pictures.

Maybe I need new glasses but that sure looks like an 11-sided table. If so, that is without a doubt the weirdest configuration I've seen. 8-sided, sure. 12-sided, sure. But 11-sided??? I agree that round would make more sense, and should be pretty easy to do. But if you can use the wood and can't use the table, I don't see anything wrong with that.

I'm usually wrong...but I like this table. It speaks to me. I dig the shape.
yes,

(probably built by some horny old man in his garage, out of 1 piece of teak).

Hahahaha, good one Mark!
I like the look as well. Would make an interesting dining table, if it's serviceable. Can't say I've ever seen an 11-sided table before. Poker tables are generally 8-sided. Casino tables are oblong and accommodate 10 players (plus dealer).
