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);
