can you use both of these on a single kettle?

the table fits on the non wheel leg centered on the handle but the pictures of the Weber Slide-Aside™ Lid Holder and looks like it is sitting between the handle and a wheel leg?

also anyone have a OTG/S with the plastic table use a Weber cover?

I actually have two of the plastic tables and the Slide-Aside. The lid sits a bit higher and rests against the side of each table. I just put some Duck tape on the place where the lid rubs against the table. Obviously, there isn't a cover for this configuration which is fine as I have a shed for storing the grill and the tables.
