e949. Packing a JTable Component

This example demonstrates how to adjust the preferred size of a JTable to be just large enough to accommodate the preferred size of all cells.

    int rows = 10;
    int cols = 5;
    JTable table = new JTable(rows, cols) {
        // Override this method so that it returns the preferred
        // size of the JTable instead of the default fixed size
        public Dimension getPreferredScrollableViewportSize() {
            return getPreferredSize();
        }
    };
    
    // Allow columns to be resized
    table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
    
    // Add data...
    
    // These packing methods are defined in e950 Packing a Column of a JTable Component
    // and e913 Setting the Height of a Row in a JTable Component
    packColumns(table, 2);
    packRows(table, 0);
