I would expect that once the NIB is in memory, changing those files  
won't have a direct effect. However, you can make the change, close  
the nib and load it again, and thus give the illusion of a variable  
number of columns (presumably the user would have to ask to add a  
column via a button or something? Then you can do this work in the  
callback)

Just guessing, but is this for basic data entry for the R bundle?
