I had a similar problem I solved it without sub classing by using a QLabel as cellwidget
(sadly i needed to use a layout, too):

int row = 0;
int column = 0;
QSize sizeIcon(32, 32);
QString iconSrc = ":/Actions/myicon.png";

QWidget *pWidget = new QWidget();
QLabel *label = new QLabel;
label->setMaximumSize(sizeIcon);
label->setScaledContents(true);
label->setPixmap(QPixmap(iconSrc));
QHBoxLayout *pLayout = new QHBoxLayout(pWidget);
pLayout->addWidget(label);
pLayout->setAlignment(Qt::AlignCenter);
pLayout->setContentsMargins(0,0,0,0);
pWidget->setLayout(pLayout);

this->ui->myTableWidget->setCellWidget(row, column, pWidget);

I used the following approach:
