show graphical interface of a jpanel in a jframe

What I did is: I created a subclass of java.swing.JPanel

public class TableInterfaceBDD extends javax.swing.JPanel

I then created all of my textfield areas, my Jtable, etc. in that class.

Then I created a subclass of java.swing.JFrame, which will be my main class

public class MainTableInterface extends javax.swing.JFrame

and I wrote this code in MainTableInterface:

public MainTableInterface() {
    initComponents();
    TableInterfaceBDD pan = new TableInterfaceBDD();
    this.setContentPane(pan);
    this.setVisible(true);
    this.validate();
}

But my graphical interface that I worked on TableInterfaceBDD doesn't show up. Can you help me with that?

My very first suggestion is to start with How to Make Frames (Main Windows) tutorial.

That being said, since your TableInterfaceBDD class is a JPanel, you can add it to another components, for instance a frame's content pane:

public class MyGui() {

    public void createAndShowGui() {

        JPanel yourCustomPanel = new TableInterfaceBDD();

        JFrame frame = new JFrame("Demo");
        frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);        
        frame.add(yourCustomPanel );
        frame.pack(); // don't forget to pack() the frame
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
}

Then in a main method:

public static void main(String[] args) {
   SwingUtilities.invokeLater(new Runnable() {
        @Override
        public void run() {
            new MyGui().createAndShowGui();
        }
    });
}

public class Main {

  public static void main(String[] args) {
    SwingUtilites.invokeLater(new Runnable() {
      public void run() {
        JFrame frame = new YourFrame(title, new YourPanel());
        frame.pack();
        frame.setVisible(true);
      }
    };
  }
}

public class YourFrame extends JFrame {
  public YourFrame(String title, JPanel panel) {
    super(title);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    add(panel, BorderLayout.CENTER);
  }
}

public class YourPanel extends JPanel {
  // your panel
}
