je suis débutante
voici mon code:

table.setPreferredScrollableViewportSize(new Dimension(800, 700));
table.setFillsViewportHeight(true);
table.getModel().addTableModelListener(this);
//Create the scroll pane and add the table to it.
JScrollPane scrollPane = new JScrollPane(table);
//Add the scroll pane to this panel.
add(scrollPane);
//JLABEL
JLabel REMPLIR = new JLabel("Remplir les valeurs " );
add(REMPLIR);
//LES BUTTONS
JButton CALCULER;
CALCULER=new JButton("CALCULER" );
add(CALCULER);
JButton Ajouter;
Ajouter=new JButton("AJOUTER" );
add(Ajouter);
}

}
}

}
System.out.println();
}
System.out.println("SSS" );
}
}
// Create the GUI and show it. For thread safety,
private static void createAndShowGUI() {
//Create and set up the window.
