code: public void newTable()
      {
          table = new Table(0);
          column = new Table(0);
          columns = 1;
          super.add(table);
          table.newRow();
          table.addCell(column).top();    
      }

  Anything added to the Composite parent of
  this object before this is called will be added between the two
  tables.
