sos help in jbutton -jtable

[nor]

hello ,
i am new in java and i have a project on creating a 6button menu in a gui application by using netbeans.
I created the menu using jframe and then i started designing the code for the first button-option.
The first option is that if selected by user a jtable must appear with 12 details for 7 employees which details are given in a txt file.
These details are given in this order:
code,name,surname,address,city,postCode,phone,emai l,department(int),typeOfEmployee,wage,typeOfEmploy ee

I also created the code for reading the txt file and create the jtable

The problems:
1) when running the jtable opens automatically together with the menu pannel
2) it appears to be empty

the code for creating the jtable is :

package paradoteo3o;
import java.awt.*;
import java.io.*;
import java.util.*;
import javax.swing.*;
import javax.swing.table.DefaultTableModel;
/**

public class menu extends JPanel{
public static final String file_name = "Employees.txt";
public static final String[] columns = {"Κωδικός Εργαζομένου", "Όνομα", "Επίθετο", "Διεύθυνση","Πόλη","Τ.Κ","Τηλέφωνο","Email","Τμήμα ","Τύπος Εργαζομένου","Μισθός","Κωδικός Κάρτας"};

private JTable table=new JTable();
private DefaultTableModel model;

public menu(){
setLayout(new BorderLayout());
add(new JScrollPane(table),BorderLayout.CENTER);

Vector <String> columnNames=new Vector <String>(Arrays.asList(columns));

try {
Scanner scanner=new Scanner(new File(file_name));
int count=0;
Vector<Vector<String>> dataVector=new Vector<Vector<String>>();
Vector<String> rowVector=new Vector<String>();
while (scanner.hasNextLine()){
String line=scanner.nextLine();
rowVector.add(line);
count++;
count %=columns.length;
if (count==0){
dataVector.add(rowVector);
rowVector=new Vector<String>();
}
}
model=new DefaultTableModel(dataVector,columnNames);
table.setModel(model);
}
catch (FileNotFoundException e){
e.printStackTrace();
}


}

static void createAndShowGui(){
JFrame frame=new JFrame("ΠΡΟΒΟΛΗ ΣΤΟΙΧΕΙΩΝ ΕΡΓΑΖΟΜΕΝΩΝ");
frame.getContentPane().add(new menu());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOS E);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}

public static void main(String[] args) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
createAndShowGui();
}
});
}
}

Is the data in your Employees.txt file comma separated, one line per employee?

If so, you need to split the line and add each field to the rowVector.
