Can't get rid of the JTable's white column divider

Question

I want a JTable that has no grid lines and no space between cells, with or with out headers. Basicly all cells should butt against each other with no grid lines.
So far I have succeeded with this, with a exception to some white divider that is about 2 pixils wide that separates each column. I tried every JTable, Header, Column Model, Table Model, Cell Renderer, etc method that sounds like it. Nothing seems to work.
If anyone knows how to do this, or has any ideas please post them...
Thanks,
Rodney

Not sure exactly what you are wanting, but here is some code in which the grid is gone. Basically, I have just set the "setShowGrid" parameter to "false". You can uncomment out the "setBackground" line and see that it works with other backgrounds.
import java.awt.Color;
import java.awt.Dimension;
import java.awt.GridLayout;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
public class TableTestFrame extends JFrame
    public TableTestFrame()
        super("Table Test");
        setSize(300,150);
        getContentPane().setLayout(new GridLayout(1,1));
        JScrollPane scrollPane = new JScrollPane();
        getContentPane().add(scrollPane);
        JTable table = new JTable(5,5);
        //table.setBackground(Color.black);
        table.setShowGrid(false);
        scrollPane.getViewport().add(table);
        addWindowListener(new WindowAdapter()
            public void windowClosing(WindowEvent event)
                dispose();
                System.exit(0);
    public static void main(String[] args)
        (new TableTestFrame()).setVisible(true);
