You may be looking for something more formal, but we ended up using a single, extra-large drum shade in our dining area.

Otherwise, this is nice, though more detailed than your inspiration above:

And I really like this one, but again, it seems a bit less formal:

You might also want to consider just hanging multiple drum-shade pendants (two or three, depending how large the table is).

(Side note - I'm only linking to BBC because it's where we looked for several lights - I have no affiliation! If you do a detailed search for Island/Pool Table lights and then select "Drum Shades" for fixture type, you can see several options.)

Hope that helps!
