[cp-patches] FYI: more JTable fixes

[Roman Kennke]

Hi,

I fixed two little problems that I had with JTable:

1. The table headers were not initialized correctly. That was introduced
by myself earlier this day. The table header values have to be initialized
in JTable.createDefaultColumnsFromMode().

2. The table columns were a little bit misaligned. I have spotted an empty
space of 1 pixel between each table header cell and the table grid was
also painted with an offset of 1 pixel. This was caused by a wrong
assumption in the calculation of the table cell rectangles. The method
TableColumnModel.getWidth() is supposed to return the column width
_including_ the gap between the cells. The calculations have added one
more pixel per column. This had the effect that with large tables the
offsets could sum up to a significant increase in table width.

All in all the JTable should look a little better now :-)

        * javax/swing/JTable.java
        (getCellRect): Don't include cell gap in cell rectangle
        calculation. It's already included in TableColumnModel.getWidth().
        (createDefaultColumnsFromModel): Initialize table header values.
        * javax/swing/plaf/basic/BasicTableUI.java
        (paint): Don't include cell gap in cell rectangle
        calculation. It's already included in TableColumnModel.getWidth().
