e945. Creating a Scrollable JTable Component

    // Create a table with 10 rows and 5 columns
    JTable table = new JTable(10, 5);
    
    // Make the table vertically scrollable
    JScrollPane scrollPane = new JScrollPane(table);

By default, a table is created with auto resize enabled. This means that if the user changes the width of the table, the columns automatically expand or shrink so that all the columns are entirely visible. In this mode, there is no need for a horizontal scrollbar. In order to get horizontal scrolling, auto resize must be disabled.

    // Disable auto resizing to make the table horizontal scrollable
    table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
