[SOLVED] JTable DataModel - how to get

[AZMichael]

Hi y'all;

I am creating a project where I use a JTable that i create by specifying rows and columns
for example:

JTable jt = new JTable(10,30);

So, how can I access (and manipulate) the underlying array if I have not used an array to create the table. That is, how can I get to
jt DataModel DataVector elementData


Thanks for your help.

        JTable table = new JTable(10,10);
        Vector rows = ((DefaultTableModel)table.getModel()).getDataVector();
        for(int j = 0; j < rows.size(); j++) {
            Vector v = (Vector)rows.get(j);
            for(int k = 0; k < v.size(); k++) {
                System.out.print("*");
                if(k < v.size()-1)
                    System.out.print(" ");
                else
                    System.out.println();
            }
        }
        Dimension d = table.getPreferredSize();
        d.width = 400;
        table.setPreferredScrollableViewportSize(d);
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.add(new JScrollPane(table));
        f.pack();
        f.setLocation(200,200);
        f.setVisible(true);
