I also have an adjustable table and at a working height of 115cm it works well with the cables.

The thick VGA cable, which connects one of the 2 front speakers permanently installed as a control unit with the subwoofer via a 15-pin D-Sub connector, is around 2 metres long.

I raise my bar table to 103cm and don't have any bottlenecks with the cables. My sub is to the left of the table, if it's too tight for you or the cables are too tight, you can also put the sub on the right to keep the distance with the wide cable to the right control box shorter ;)

All the cables described are approx. 1.5 metres. The cable to the source could be replaced by a longer one. The ones to the speakers are fixed and special, I don't know if there are extensions available. The 1 metre height should be sufficient, otherwise simply place the subwoofer on a box (not directly on the floor)
