For all the big cryptocurrencies, the price assume that you can buy unlimited hashing power if you have the money. That's obviously not true. Once you have rented all available hardware, having more money to spend won't help.
That's what the "NiceHash-able" column is for. To put it simply, if it is less than 100%, you are going to have trouble renting enough hashing power, and conducting the attack will be impossible in practice, or at least much more expensive than the listed price.
