Well the most important moves you'll need a lot of weight for is the squat and the deadlift. If you have to choose between the two though, go with the squat. You could go rice farmer and get a metal bar and put water in buckets. If it spills, you weren't stable enough. Put some tape on the ends, or rope.
1 gallon of water = 8.35 lbs.
2 x 5 gallons of water = 83.5 lbs.
4 x 5 gallons of water = 167 lbs.
You could fill it to the very top for extra weight, and the added difficulty of keeping it from spilling (no swaying, build the stabilizers and mental strength n' focus). Or fill it with rocks. You'll need the flexibility to squat low enough to drop it.
The awkward leverage would be great though. Arms and shoulders are good, lift from the small bottom end and the long forward weight will multiply the difficulty. You can put your feet under something and lay on the ground, then bring the table over head in a pull over motion. Use your counter top in the kitchen or something to do korean dips, feet against the cupboard/low wall. Could do cossack squats.
