Formatting JTable columns

[Douglas Kent]

Has anyone done other than the default left-justified columns? I'd like to center the airports, and right-justify and add dollar signs to the cost column. Cannot find a clear reference in the java.sun documentation...

You'll need a component that implelments TableCellRendere, somthing like: class MyCellRenderer extends JLabel implements TableCellRenderer.
Read the Java Tutorial on JTable in Swing section. Customizing table cells is straight forward but customizing Headers is little bit more involved.

Ok, I used a class extending JLabel and implementing cell renderer. It works BUT, if I do not implement it, there is no change of background color when the row of the JTable is selected. It remains a simple JLabel all the time.
So, in my renderer class, I would like to write:
if (isSelected == true){this.setBackground =Color.white;}
else {this.setBackground = Color.???}
"this" is the JLabel.
But how to get the appropriate color to highlight?On my computer,
the higlight color of the default renderer is a "Lavande" color, that is blue grey purple. Does the color remain the same on all the platform, PLAF, setting?
Or should I get a system property, a color model??? I can not find my answer in the API.
Thanks for your help

Just get the color using theTable.getSelectionForeground/Background()
