Anyone know if there's a method to block up the holes/pockets in a billiard table?

I like to play what's called carom billiards (http://en.wikipedia.org/wiki/Carom_billiards), which means i want a table with no holes, something that i cant find in america.....is there some way (maybe some billiard table accesory or diy style) to block up the holes and make the corners smooth like in the picture on the wikipedia article?
