Problem with adding a row filter to JTable

[LianaN]

Hi guys!

I have a problem with adding a row filter to the JTable component. Below is a code that I'm using:

public class FilterClass extends JPanel {
    TableRowSorter rowSorter;
    private DefaultTableModel tableModel;

    public FilterClass() {
        //super(new GridLayout(1,0));
        initComponents();
        rowSorter=new TableRowSorter();
        tableModel = (DefaultTableModel) tableDetails.getModel();
        rowSorter.setModel(tableModel);
        tableDetails.setRowSorter(rowSorter);
    }

    private void initComponents() {

        tableDetails = new javax.swing.JTable();
        txtFirstName = new javax.swing.JTextField();
        txtLastName = new javax.swing.JTextField();

        //setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        tableDetails.setModel(new javax.swing.table.DefaultTableModel(
            new Object [][] {
                {"103", "AAA","BBB"},
                {"104", "CCC","DDD"},
                {"105", "EEE","FFF"},
            },
            new String [] {"ID",
                          "Name",
                          "Surename"}
        ));
        tableDetails.setFillsViewportHeight(true);
        jScrollPane1 = new javax.swing.JScrollPane(tableDetails);
        add(jScrollPane1);

        txtFirstName.addKeyListener(new java.awt.event.KeyAdapter() {
            public void keyReleased(java.awt.event.KeyEvent evt) {
                txFirstNameKeyReleased(evt);
            }
        });

        txtLastName.addKeyListener(new java.awt.event.KeyAdapter() {
            public void keyReleased(java.awt.event.KeyEvent evt) {
                txtLastNameKeyReleased(evt);
            }
        });
    }

    private void txFirstNameKeyReleased(java.awt.event.KeyEvent evt) {
        rowSorter.setRowFilter(RowFilter.regexFilter("(?i)^"+txtFirstName.getText(), 0));
    }

    private void txtLastNameKeyReleased(java.awt.event.KeyEvent evt) {
        rowSorter.setRowFilter(RowFilter.regexFilter("(?i)^" +txtLastName.getText(), 1));
    }

    private javax.swing.JScrollPane jScrollPane1;
    private javax.swing.JTable tableDetails;
    private javax.swing.JTextField txtFirstName;
    private javax.swing.JTextField txtLastName;

}

FilterClass fc = new FilterClass();
        fc.setVisible(true);
        fc.setBounds(10, 50, 620, 200);
        panfortab.add(fc); //panfortab is the JPanel component

The problem is that the rows "txtFirstName" & "txtLastName" are not displayed. What could be wrong with this code?
