				  e931. Showing the Table Header in a Non-Scrollable JTable Component
				
				By default, if you don't place a table component in a scroll pane, the
				table header is not shown. You need to explicitly display it.
				
				
				    int rows = 10;
				    int cols = 5;
				    JTable table = new JTable(rows, cols);
				    JTableHeader header = table.getTableHeader();
				    
				    container.setLayout(new BorderLayout());
				    
				    // Add header in NORTH slot
				    container.add(header, BorderLayout.NORTH);
				    
				    // Add table itself to CENTER slot
				    container.add(table, BorderLayout.CENTER);
