row reversal in tables

I have a NSTableView configured through IB.

Certain of its columns should allow row sorting. I understand this is 
accomplished by setting the Create Sort Descriptor checkbox in the 
bindings panel. It works.

But all rows reverse order when clicked in the column header of the 
table.
Is it possible to restrict that change in row order to stricly the 
columns having the sorting action on them? If so, how?

Or is the row reversal on clicking the column headers so ingrained in 
the OS that it cannot be changed? I can live with that fact, but 
otherwise would like to customize the behaviour of my tables as 
indicated above.
