Как сделать метки, размещенные на QGridLayout, более последовательными?

Question

Я делаю простую программу, которая читает некоторые данные из базы данных и отображает их в окне. Я решил использовать QGridLayout из PyQt5, но не могу go устранить несоответствие ширины надписей, размещенных на этом макете. Ниже приведена урезанная версия со случайными текстами вместо данных базы данных. Я бы хотел ВСЕГДА растягивать некоторые метки вправо, но иногда (в зависимости от текста) они занимают только часть пространства, предназначенного для них. Что я делаю не так? Примеры: Кнопка «Refre sh» изменяет текст на другой случайный тип, а также изменяет макет. Код:

Извините, но я не понимаю, зачем все время реформировать

new_label = QLabel (label_text)

и зачем вам нужен clear_layout метод
