在QStyledItemDelegate的paint方法里面

void MyItemModelDeletage::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const

    HtItemModelDeletage::paint(painter,option,index);

    if(index.column() == 0)

                painter->save();

                QPushButton *button = new QPushButton(this);

                button->resize(option.rect.size() );

                painter->translate(option.rect.topLeft());

                button->render(painter, QPoint(), QRegion(), QWidget::DrawChildren );

                painter->restore();

}
