JTable Focus Movement Query?

I am trying to highlight the focus movement in the JTable through this code:

    if(e.getKeyCode() == (KeyEvent.VK_TAB)){
                int prevRow;
                int row = table.getSelectedRow();
                int col = table.getSelectedColumn();
                if(col == 0) {
                System.out.println(row);
                MinMax val = null;
                TableCellRenderer currRend = table.getCellRenderer(row,col);
                val = (MinMax) table.getValueAt(row, col);
                JComponent comp = (JComponent) currRend.getTableCellRendererComponent(table, val, false, false, row,col);
                comp.setBorder(BorderFactory.createLineBorder(Color.RED));
                table.requestFocus(true);   
}

The scenario is this, when I press TAB for the first time the second row is selected, initially the focus is set on row[0], the border is not painted, when I press the second time the third row is selected highlighting both 2 and 3rd row.

After that whenever tab is pressed, the highlighting of the border becomes relevant to the row selection.

I am facing issue when I am running the application under normal mode and not under de-bugger mode with break points.

There no reason for bothering with KeyEvents from KeyListener, if not generated some extra special Events, implements prepareRenderer, and there you have to test if is isSelected() or hasFocus(), I think that everything and nothing better around as @camickr's Table Row Rendering,
