title: JTable insert column instead of rows
body: <p>Is it possible for a <code>JTable</code> to have static rows and dynamically inserted columns (i.e. instead of inserting rows, to insert columns), as presented below?</p>
  
  <pre><code>  DefaultTableModel model = new DefaultTableModel(String[], String[][]);
  
    String rows[] = {"row1","row2"};
    String columns[][] = {{"A","100"},{"B","200"},{"C","300"}};
    DefaultTableModel model = new DefaultTableModel(rows,columns);
    JTable table = new JTable(model);
  </code></pre>
