Sometimes you want to bind a tableview column to objects that might not support that particular binding (like having an uber-overview tableview for core data entities that don't all share the same attributes). If your column has a numeric formatter, IB won't let you specify a string for the "not applicable" value, so you end up with a really ugly tableview covered in "Not Applicable"sPut this in a convenient place:
+ (void) initialize { [NSTextFieldCell setDefaultPlaceholder: @"" forMarker: NSNotApplicableMarker withBinding: NSValueBinding]; } // initialize
