Как в Qt Designer создать элемент с динамически меняющемся массивом данных?
Имеется приложение (не на PyQt5 Qt Designer), в котором при вводе в поле шаг автоматически заполняется столбец время, а при вводе в поле количество точек изменяется размерность таблицы.
А также имеется возможность заполнения столбца Выход данными.
Как можно реализовать данный функционал в PyQt5 Qt Designer ?

Я не знаю какое приложение у вас имеется.
Такой функционал нельзя сделать в Qt Designer.
Возможный вариант может выглядеть примерно так. С надеждой, что в следующих вопросах вы будите предоставлять минимально-воспроизводимый пример.
