У меня есть таблица с результатами поиска, и мне нужно отсортировать один из столбцов в алфавитном порядке.Когда я нажимаю на столбец, я хочу, чтобы записи в этом столбце были отсортированы, но метод, который я реализовал, не сработал.Я также пытался использовать метод Лодаша sortBy, но он все равно не сортировал столбец должным образом.
