   It looks like from the picture that top was left outside or is an outside table. If so, there is nothing you can do to 'fix' it. Wood boards exposed to lots of water will warp as shown in your picture. Even kiln dried wide boards used inside will show similar, but much milder cupping. It is just wood being wood.

   I'd make it a feature and call it a cupped table.

   Still tempting to run a power planer over the crowns. Thoughts on that? Thanks

   After ripping them in half that should leave enough thickness for another 10 years.

   Horizontal boards outdoors always cup upward. You can rip, plane, reattach, but wood outside will react.

   Wood's gonna do whats it's gonna do. I have learned this lesson over and over.

   Can anyone see the discoloration in the b&w photo?

   They all look like a thin board face glued to a thicker one, the lower one not having any cupping. I wonder if you can separate them and replace the tops if you want that thickness. Maybe even turn them upside down, and fill a few screw holes.
