Transport category aircraft are tested and certified with the data contained in those tables. Outside of that is the certified limitation because there isn't data available to fly given those conditions. The planes are perfectly capable of doing much better than what they are certified for, but it would have cost more to certify all of them for the narrow set of circumstances a few might need intermittently.
