Стили ячеек QTableWidget при редактировании

Из того, что я понял, вы не желаете чтобы при редактировании ячейки таблицы менялся цвет фона ячейки.

Как вариант. Когда вы выполняете редактирование ячейки, где-то под капотом вызывается виджет QLineEdit и все что я вам предлагаю попробовать - это добавить в таблицу стилей :

" /* +++ vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv +++ */ \n"
"QLineEdit {\n"
"   border: None;\n"
"   background: #E88327;\n" 
"}\n"
"\n"
" /* +++ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +++ */ \n"

Терминология и синтаксические правила таблицы стилей Qt: http://doc.qt.io/qt-5/stylesheet-syntax.html

Таблицы стилей Qt поддерживают различные свойства, псевдосостояния и субэлементы управления, которые позволяют настраивать внешний вид виджетов: https://doc.qt.io/qt-5/stylesheet-reference.html

Несколько примеров, чтобы начать работу с таблицами стилей Qt: http://doc.qt.io/archives/qt-4.8/stylesheet-examples.html
