No the trays we are talking about are designed for scooters. We live close to DLR and drive in for the F&W event. We designed these trays for Taste which happens the last weekend of DCA F&W. It is the equivalent of PFTS in CA and happens only one night at the end of the festival since most of the people who attend the CA event are locals. We could drive in and not have to worry about luggage onboard a plane. My partner can not walk distances and I can not stand for long periods of time so this worked for us. She could use her scooter for something like the Wine View Lounge while I could use the table. We built them from wood and edging at Home Depot and used a planter support as the mounting element. She was quite ingenious in designing them. We strap them on with multiple zip ties and they work quite well. If we can't have a dedicated space then we both use the scooters with the tray tables. They are a little difficult to navigate with, but make it possible for us to attend these sorts of "tasting events".
