public class TableDemo extends JPanel {

    static List<String[]> rosterList = new ArrayList<String[]>();

    private static Icon leftButtonIcon;
    private boolean DEBUG = false;
     // added static infront becuase got non static referencing error
static List<String[]> rosterList = new ArrayList<String[]>();

    public TableDemo() {
        super(new GridLayout(1,0));

        JTable table = new JTable(new MyTableModel());
        table.setPreferredScrollableViewportSize(new Dimension(500, 70));
        table.setFillsViewportHeight(true);

       JButton button=new JButton("Buy it");
       button.setSize(30,60);
