to keep the bus wires taut without sagging, I designed in a counterweight system. At the right side of the table, I added a screw to the underside. The bus wires passed over the top of the screw with a few inches of excess hanging down. Then, I added some old screws to a ziplock bag and attached that to the end of the bus wires. It had the effect of adding some tension to the bus wires and kept them up near the table. I thought it was a clever idea.
