Issues with the JTable

1. Header focus is not traversable and some of the keybindings is not working

To Reproduce: Run Table Demo from SwingSet2, click on a table cell, and press F8 to transfer the focus to the table header. The table header gets the focus but pressing the left/right arrow keys is not moving the focus around. And pressing the Alt + Left /Right arrows is not reordering (moving) the columns

2. Color: Please see the attached screen shot. Notice the Favorite Color Column of the table. From row 3 to 7, Win XP Look and Feel is displaying the Black color correctly whereas Nimbus does not display the Black color, other color looks ok.

3. Sorting: Please refer the screen shot, table is sorted by Favorite Color, looks like this could be related to issue 2. Notice the sorting order of the First Name, Last Name etc., in XP and Nimbus. Sorting by other columns works ok.
