когда таблица фокус теряет, вроде как виджет-редактор закрывается, т.е. уже представление сигнал посылает.
Но в моем случае почему-то только после нажатия ентер срабатывает. А при потере таблицей фокуса нет
Вот код:

return le;
//QRegExp rx("[a-zA-Zа-яА-Я0-9]{1,12}");

QString string = index.model()->data(index).toString();
QLineEdit *le = static_cast<QLineEdit* >(editor);
le->setStyleSheet("*{selection-background-color: green}");
