How to use the @alifd/next.Calendar.RangeCalendar function in @alifd/next

switch (index) {
                case 0:
                    d.year(number);
                    break;
                case 1:
                    d.month(number - 1);
                    break;
                case 2:
                    d.date(number);
                    break;
                default: return;
            }
        });

        if (shape === 'rangePanel') {
            if (!Calendar.RangeCalendar) return null;

            return (
                
            );
        }
        return (
            
        );
    }
};
