Updating the existing JTable !

[Stephen Douglas]

Hello:) I need to update the JTable i created using the ide which created the code something like. this...

        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},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null}
            },
            new String [] {
                "            INVOICE_TYPE", "         CUSTOMER_ NAME       ", "         CUSTOMER_ADDRESS", "               TIN_NUMBER"
            }
        ) {
            Class[] types = new Class [] {
                java.lang.String.class, java.lang.String.class, java.lang.String.class, java.lang.String.class
            };
            boolean[] canEdit = new boolean [] {
                false, false, false, false
            };

            public Class getColumnClass(int columnIndex) {
                return types [columnIndex];
            }

            public boolean isCellEditable(int rowIndex, int columnIndex) {
                return canEdit [columnIndex];
            }
        });
        jTable1.setRowHeight(20);
        jScrollPane1.setViewportView(jTable1);

        jPanel5.add(jScrollPane1, java.awt.BorderLayout.CENTER);

        jTabbedPane1.addTab("EXTEND", jPanel5);

        getContentPane().add(jTabbedPane1, java.awt.BorderLayout.CENTER);

Now i need to update this existing JTable.. I have no idea how to do that.. have been trying things.. but none seems to be working..

please suggest.:confused:

table.setValueAt(...);

Also there is no need for initializing the table like that. Read the DefaultTableModel API for a constructor that allows you to specify the column names and the number of empty rows.
