JTable Row Height Problem

[Edsoncv]

I'm having the following problem while configuring a JTable row
height.
The fact is when my row height does not have the exactly heigth of
"row header", exactly figure bellow:

The line height seems almost the same but this little difference
increases as the # of rows increase or the look and feel is changed.

My code is very similar like this:

/* (swing1.1beta3) */

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.*;


/**
* @version 1.0 11/09/98
*/

class RowHeaderRenderer extends JLabel implements ListCellRenderer {

RowHeaderRenderer(JTable table) {
JTableHeader header = table.getTableHeader();
setOpaque(true);
setBorder(UIManager.getBorder("TableHeader.cellBorder"));
setHorizontalAlignment(CENTER);
setForeground(header.getForeground());
setBackground(header.getBackground());
setFont(header.getFont());
}

public Component getListCellRendererComponent( JList list,
Object value, int index, boolean isSelected, boolean
cellHasFocus) {
setText((value == null) ? "" : value.toString());
return this;
}
}

public class RowHeaderExample extends JFrame {

public RowHeaderExample() {
super( "Row Header Example" );
setSize( 300, 150 );

ListModel lm = new AbstractListModel() {
String headers[] = {"a", "b", "c", "d", "e", "f", "g", "h",
"i"};
public int getSize() { return headers.length; }
public Object getElementAt(int index) {
return headers[index];
}
};

DefaultTableModel dm = new DefaultTableModel(lm.getSize(),10);
JTable table = new JTable( dm );
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

JList rowHeader = new JList(lm);
rowHeader.setFixedCellWidth(50);

rowHeader.setFixedCellHeight(table.getRowHeight()
+ table.getRowMargin());
// + table.getIntercellSpacing().height);
rowHeader.setCellRenderer(new RowHeaderRenderer(table));

JScrollPane scroll = new JScrollPane( table );
scroll.setRowHeaderView(rowHeader);
getContentPane().add(scroll, BorderLayout.CENTER);
}

public static void main(String[] args) {
RowHeaderExample frame = new RowHeaderExample();
frame.addWindowListener( new WindowAdapter() {
public void windowClosing( WindowEvent e ) {
System.exit(0);
}
});
frame.setVisible(true);
}
}
