QTableWidge中插入图片作为图标

    QLabel *label=new QLabel();
    QPixmap pixmap(QDir::currentPath()+"/operation.png");
    label->setPixmap(pixmap);
    label->setStyleSheet("background-color: rgb(14, 18, 28);");
    label->setAlignment(Qt::AlignCenter | Qt::AlignVCenter);//将图片在QLabel中居中
    point_task_tableWidget->setCellWidget(point_task_tableWidget->rowCount()-1,3,label);
