JTable not showing up....

Question

Hello,
I'm working with a JTable and having a slight problem. The JTable never shows up and I'm not sure why because when I debug it, data[][] has all the correct values. If someone could just point me in the right direction it would be greatly appreciated. Here is my code. It is self contained.
import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
public class FillingHistoryTable extends JPanel {
    JTable fhTable;
    JScrollPane tableHolder;
    public static void main(String[] args){
        JFrame f = new JFrame("FHTABLE");
        f.getContentPane().add(new FillingHistoryTable());
        f.setVisible(true);
    public FillingHistoryTable(){
        initComponents();
    private void initComponents(){
        fhTableModel model = new fhTableModel();
        model.initModel();
        fhTable = new JTable(model);
        fhTable.setPreferredScrollableViewportSize(new Dimension(500, 70));
        fhTable.setFillsViewportHeight(true);
        tableHolder = new JScrollPane(tableHolder);
        buildComponents();
    private void buildComponents(){
        this.add(tableHolder);
        this.setVisible(true);
    class fhTableModel extends DefaultTableModel {
        private String[] columnNames = {"Year", "Waste in tons"};
        private Object[][] data;
        private int currentYear = 2008;
        private int openYear = 1998;
        private int yearsOpen = currentYear - openYear;
        public void initModel(){
            data = new Object[yearsOpen + 1][2];
            for(int row = 0; row <= yearsOpen; row++){
                for(int col = 0; col < 2; col++){
                    if (col == 0){
                        data[row][col] = currentYear;
                    else{
                        data[row][col] = 0;
                currentYear = currentYear - 1;
}

Answer 1

are you adding your scrollpane to itself?
tableHolder = new JScrollPane(tableHolder);Something tells me that you need to add your JTable to a JScrollPane at some point or another.
