Table model not displaying in Java

Question

In my table model, I give it the data, put it in a 2d array, but it still does not show up. This table model has worked for me in the past, so I have no idea why it is not. Nothing is displayed when using this. I KNOW for a fact that the data 2D array is getting data in it.

public class Returns extends javax.swing.JFrame {
    SearchTableModel stm;
    public Returns() {
        stm = new SearchTableModel();
        initComponents();
    }

    public void search(String query) {
        stm.search(query);
    }
    @SuppressWarnings("unchecked")
    private void initComponents() {
        jScrollPane2 = new javax.swing.JScrollPane();
        jTable2 = new javax.swing.JTable();
        jTable2.setModel(stm);
        jTable2.setMinimumSize(new java.awt.Dimension(200, 200));
        jScrollPane2.setViewportView(jTable2);
        javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
        getContentPane().setLayout(layout);
        layout.setHorizontalGroup(
        layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addComponent(jScrollPane2, javax.swing.GroupLayout.DEFAULT_SIZE, 1255, Short.MAX_VALUE));
        layout.setVerticalGroup(
        layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addComponent(jScrollPane2, javax.swing.GroupLayout.DEFAULT_SIZE, 651, Short.MAX_VALUE));
        pack();
    }
