You’ll need to step back to show more of the room if you want ideas. All I can see is that the lamp takes up most all of the table . Are you seriosly asking what very small objects would look good or be functional? I’d suggest each side should hold a pretty coaster. In the middle, a lovely porcelain or crystal bowl holding your choice of nuts or candies for guests.. My bowl holds ancient family marbles.

I think a couple of coasters would look nice and be useful

Your lamp is a beautiful statement. why compete with it?
