2nd row captain seats and cargo cover?

I was looking to remove the 3rd row seats and buy either an OEM cargo cover or one of the ones from China. However, in every picture of the cargo cover, it is being used with split bench 2nd row seats. Has anyone installed this with the captain's seats? I'm thinking it might look weird with that open space between the captain's chairs.
