        new SortPagination.SortParam("age", true), 
        new SortPagination.SortParam("city", true)
);
List<SortPagination<Person>> sortOrders = SortPagination.createSortPagination(sortParams, columnMap);
Pageable pageable = Pageable.ofSize(3).withPage(0); 

Page<Person> resultPage = SortPagination.sortAndPageData(people, sortOrders, pageable);
