The index of the column containing
view in the
table array. This method returns
-1 if the view is not in the table view. This method may also return
-1 if the row containing the view is being animated away, such as during the deletion of a row.
This method is typically called in the action method of an
NSControl) to find out what row (and column) the action should be performed on.
