JTable füllen mit addRow()

[Orhan Polat]

Hi,

ich möchte eine ganz billige Sache tun. Undzwar erzeuge ich ein JTable mit einem DefaultTableModel und einem DefaultTableColumnModel. Ich erzeuge 3 TableColumns. Bisher alles Ok ! Ich kann mein Jtable sehen mit den 3 Spalten
sobald ich mit tableModel.addRow(data) ein Eintrag hinzufügen möchte bekomme ich ein Fehler. Ich kann mir diesen blöden Fehler nicht erklären.

Hier der Code vielleicht kann mir jemand helfen ?

package bizztalk;

import java.awt.*;
import javax.swing.*;
import javax.swing.table.*;
import java.util.*;

public class RequestState extends JFrame
{
private JTable jTable1;
private DefaultTableModel tableModel = new DefaultTableModel();
DefaultTableColumnModel columnModel = new DefaultTableColumnModel();

public RequestState()
{

this.getContentPane().setLayout(new BorderLayout());

TableColumn col1 = new TableColumn();
col1.setHeaderValue("Kunden Nr.");
TableColumn col2 = new TableColumn();
col2.setHeaderValue("Preis");
TableColumn col3 = new TableColumn();
col3.setHeaderValue("Bonität");
TableColumn col4 = new TableColumn();
col4.setHeaderValue("Bonität");

columnModel.addColumn(col1);
columnModel.addColumn(col2);
columnModel.addColumn(col3);

jTable1 = new JTable(tableModel,columnModel);

getContentPane().add(new JScrollPane(jTable1),"Center");

String[] data = {"Id","Preis","Bonitt"};

tableModel.addRow(data); // Fehler bei dieser Zeile

}
public static void main(String[] args)
{
RequestState requestState = new RequestState();
requestState.setVisible(true);
requestState.pack();
}
}

hier die geworfene Exception:

Hallo !

hast du da bereits daten in der Table ?
Wenn nicht musst bevor du daten addest, zuerst ein Object[] erstellen, zu dem das neue Object[] adden kannst !
