Set JTable header background, foreground and border

Setting a JTable header backgound color is similar to setting a JTable column background, both are done through the TableCellRenderer.

JTable table = new JTable(model);
table.getTableHeader().setDefaultRenderer(new MyTableHeaderRenderer());

public class MyTableHeaderRenderer extends DefaultTableCellRenderer {

        @Override
        public Component getTableCellRendererComponent(
                JTable table, Object value,
                boolean isSelected,
                boolean hasFocus,
                int row, int col) {

            Component comp = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, col);
         
            //Set the header of column 3 to a particular color
            if (col == 3) {
                comp.setBackground(Color.darkGray);
                comp.setForeground(Color.WHITE);
            } else {
                comp.setBackground(new Color(250,250,250));
                comp.setForeground(Color.BLACK);
            }

            //Set all headers with a border
            ((JLabel)comp).setBorder(BasicBorders.getInternalFrameBorder());

            return comp;
        }
    }
