Usually, it's not really a table. Most Random Number Generators perform a series of mathematical operations on the seed, generating a "random" number and a new seed. So if you start with the same seed, as askan said, you get the same series of random numbers. Tables of random numbers exist, but, if you are using billions of them, it's a lot easier to generate them on the fly.
