Annotation ExcelAlias can add on class and properties.
    It means worksheet title when it annotated on class.
    It means column title when it annotated on property.
    
Annotation ExcelIgnore can ignore export this property.
    It means will disappear this colmun in the excel file.
For example:

    @ExcelAlias("user") //worksheet title
    pubblic class UserInfo {
        
        @ExcelAlias("User Identity") //column title
        private String id;
        
        @ExcelAlias("User Name") //column title
        private String username;
        
        @ExcelIgnore //disappear this column
        private String password;
        
        ......//getters and setters
    }
    
Of course you add nothing annotation on the class then it will use classname and property name to generate worksheet title or column title.
