Hi, @sonichy you can add text on that by finding its child QAbstractButton and then add a widget to it as QLabel using the vertical layout as below.

QAbstractButton* button = qFindChild< QAbstractButton* >(TableWidget);
if (button)
{
QVBoxLayout* lay = new QVBoxLayout(button);
lay->setContentsMargins(0, 0, 0, 0);
QLabel* label = new QLabel("No");
label->setStyleSheet("QLabel {font-face: ArialMT; font-size: 10px; color: #FFFFFF; font-weight: bold; }""QToolTip { color: #ffffff; background-color: #000000; border: 1px #000000; }");
label->setAlignment(Qt::AlignCenter);
label->setToolTip("Text");
label->setContentsMargins(2, 2, 2, 2);
lay->addWidget(label);
}
