Not a full table, but if you like this snow
http://www.dakkadakka.com/gallery/494448-Death%20Korps%20of%20Krieg%2C%20Hydra.html the recipe is simple: Woodland Scenics soft flake snow mixed with realistic water, which produces a nice icy slush. And the ingredients are pretty cheap, if you're doing a
DKoK army the snow to cover an 8x4 table will be a rounding error in the price.
Also, even if you don't like that recipe the most important lesson is to buy direct from Woodland Scenics or a similar company instead of getting ripped off for "gaming hobby" materials. I would not be at all surprised if the stuff
GW sells is all just re-branded scenery materials from "mainstream" modeling at a huge price increase, just like green stuff and all of their tools.
