JTable insert column instead of rows

Question

Is it possible for a JTable to have static rows and dynamically inserted columns (i.e. instead of inserting rows, to insert columns), as presented below?

  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);

Answer 1

Yes, update your TableModel and fireTableStructureChanged(). Naturally, editing your question to include an sscce would help.
