Я потратил час, пытаясь понять, что я делаю неправильно, но безуспешно. Ниже приведен код и изображение результата. Все строки появляются одна над другой в первой строке таблицы. и строка не расширяет ширину таблицы, как я установил в ограничениях. Что я делаю неправильно? Спасибо. Класс табличного представления:

override init(frame: CGRect, style: UITableView.Style) {

Значение selectedMimicIndex изменяется на didSelectItem() функция представления коллекции, которое у меня есть;резюме, которое контролирует, какие ячейки отображает таблица. reloadData () вызывается здесь после изменения значения Int, когда пользователь изменяет выбранную ячейку cv. 
Также обратите внимание, что второй ряд намного выше, чем должен быть;игнорирует указанную мной высоту.
