Typically, some mouse event over a column header sorts the table column (if sorting enabled). This must not happen if the event's location is in the resize region, that is if the cursor is changed to the resize cursor. Reasons:

- inconsistent with native OS behaviour (at least in windows, don't know about others)
- additionally confusing the user because she expects nothing else but resizing (seeing the visual clue for that action)
- hinders custom actions (like f.i. adjusting column widths to maximal entry width on mouse double, that's standard native behaviour - windows again



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
take your favourite sort-enable JTable example and click into the resize region


REPRODUCIBILITY :
This bug can be reproduced always.
