Am I right to say that the data stored in a contract are stored as tables and that for every row, we would have to emplace that row to a user, who would then pay for the storage?

Or is one particular user liable for the storage of the whole smart contract?

Yes, someone has to pay for the table store, i.e. RAM. You (contract) can choose who to pay. For example, in eosio.token contract, it is the "sender" paying RAM if the receiver is not in the balance table.

    yes, you can bill different accounts for different rows. like eosio.token bills different accounts for storing their own balance
