JTable cell background color move with column

The following code makes a simple table. If you drag the first column one spot to the right, the cell color follows the cells. If you move farther than 1 column, though, the color gets messed up. Any ideas? Thanks!

public class Table extends JFrame

        scrollPane1 = new JScrollPane();
        table1 = new JTable();
 
        Container contentPane = getContentPane();
        contentPane.setLayout(null);
 
        {
            scrollPane1.setViewportView(table1);
        }
        contentPane.add(scrollPane1);
        scrollPane1.setBounds(new Rectangle(new Point(0, 0), scrollPane1.getPreferredSize()));
 
        { 
            Dimension preferredSize = new Dimension();
            for(int i = 0; i < contentPane.getComponentCount(); i++) {
                Rectangle bounds = contentPane.getComponent(i).getBounds();
                preferredSize.width = Math.max(bounds.x + bounds.width, preferredSize.width);
                preferredSize.height = Math.max(bounds.y + bounds.height, preferredSize.height);
            }
            Insets insets = contentPane.getInsets();
            preferredSize.width += insets.right;
            preferredSize.height += insets.bottom;
            contentPane.setMinimumSize(preferredSize);
            contentPane.setPreferredSize(preferredSize);
        }

        int viewColumn = table.convertColumnIndexToView(column);
        if(row >0 && (!(table.getModel().getValueAt(row, viewColumn).equals(table.getModel().getValueAt(row-1, viewColumn)))))

Darryl,

Sorry about that. I assure you that I did not spam this out to every forum I could find. I've posted it that java-forums website twice over the past month, but no where else. It has me stumped and is the final requirement before delivery.
