I think it's reasonable to have two adjacent rows in the table for these
two closely related things, but rather than "columns per tuple" I would
label the second one "columns in a result set".  This is easy enough to
understand and to differentiate from the other limit.

(Replacing "in a" with "per" sounds OK to me but less natural, not sure
why.)
