Musiciansfriend sells a white table that clamps on a cymbal or hihat and holds a good bit. Google percussion table.
...put your iPod, keys, wallet, etc. under your floor tom. They won't be in the way, and you'll know exactly where they are. Just make sure to put your drink next to the hi hat so you don't accidently spill it onto said items.
Those trap tables are more trouble than they're worth, IMO...
You could somehow attach a sturdy bag to the side of your drum throne top. It's a great storage area, right?. Seat tops should have all kinds of pockets sewn all around, don't you think? You heard it here first lol.
I attached a piece of rope to the bottom my seat top, using 2 screws underneath to secure the rope. It makes it SO much easier to carry you have no idea.
Instead of a table, you could somehow attach a sturdy bag to the side or bottom of your drum throne top. It's a great storage area, right? Should be relatively safe from spills there... Seat tops should have all kinds of pockets sewn all around, don't you think? What a natural place to have spare sticks, right? Right by each side, right? You heard it here first lol.
