Fill jTable with computed data

[Juergen Baisch]

Hi,
I'm new to swing and using Netbeans 6.8.

My GUI has a jTable which I have created with Mantisse. Now I want to fill it with computed data. The data is not stored in a file or database. It is in an array of double, e.g.

double[] su = new double[i];

I always know the number of columns but not the number of rows. The number or rows varies.
What I have got from Mantisse is:

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, null, null},
        {null, null, null, null, null, null}
    },
    new String [] {
        "Date", "Sunrise", "Sunset", "Daylight", "%_day", "%_month"
    }
) {
    Class[] types = new Class [] {
        java.lang.String.class, java.lang.String.class, java.lang.String.class, java.lang.String.class, java.lang.Double.class, java.lang.Double.class
    };

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

jTable1.setName("jTable1"); // NOI18N

jScrollPane1.setViewportView(jTable1);

How have I to modify the code to get it working?

Thank you very much in advance.

First, keep a reference to your DefaultTableModel.

Second, when you want to add a row to the table, call the addRow() method on that DefaultTableModel.
