@BeverlyFLADeziner: No, I'm not assuming the back has a finish. If you are referring to the cable being visible, or the approach to route it under the sofa would not work, there are two options: Align the table so that the "backless" back is up against the side of the sofa. So, flip it 90deg compared to the image of a sample sofa and this table posted earlier. The cable can be stuck along the curved edge of the table on the back, so that it is not visible. This way, it gets down to the floor along a surface that people cannot see as opposed to dangling through the hollow portion of the table.

Hi, you can nicely put a beautiful runner on the center of the table, with placemats, bamboo tray with all accessories like salt and pepper, paper napkin, nice cutlery, LED candle, you have lot of options. check pinterest for more designs.

These are called wooden pellet or pallet. You can order them online . Scrap dealers around manufacturing logistics industrial areas usually sell these as well.
