Le code du jTable

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

jTable1 = new javax.swing.JTable();   jTable1.setModel(new javax.swing.table.DefaultTableModel( new Object [][] { {null, null, null, null}, {null, null, null, null}, {null, null, null, null}, {null, null, null, null} }, new String [] { "Date", "Motif", "Ville", "Km","Frais en Euro" } ));   jScrollPane2.setViewportView(jTable1);

Déja tu ne nous dis pas le problème exactement, je vais donc tenter de deviner :

Code:

---

1 2 3 4 5 6 7 8 9 10

new javax.swing.table.DefaultTableModel( new Object [][] { {null, null, null, null}, {null, null, null, null}, {null, null, null, null}, {null, null, null, null} }, new String [] { "Date", "Motif", "Ville", "Km","Frais en Euro" }

Tu as 5 colonnes et dans ton Object[][] tu en déclares 4 (bizarre) et en plus tu les mets a null (mauvaise idée).
