Will a cable tray work with a sit-stand or motorized standing desk?

Yes, and it's actually where trays matter most, since loose cables can snag on the lift mechanism. Reviewers consistently recommend clamp-on or screw-mounted metal or fabric trays for standing desks because adhesive can fail under the repeated motion and weight shifts. Look for a tray long enough to corral a power strip plus all device bricks so nothing dangles.
