    //表格表头的显示与隐藏

    tableWidget->horizontalHeader()->setVisible(false); //隐藏行表头

    //tableWidget->setEditTriggers(QAbstractItemView::NoEditTriggers);

    //设置行高

    for(int i= 0; i< tableWidget->rowCount(); i++)

    // 单元格中添加控件并居中

     QLabel* label = new QLabel("gender");

     QComboBox *comBox = new QComboBox();

     comBox->setFixedSize(100, 25);

     comBox->addItem("F");

     comBox->addItem("M");

     // 单元格中的控件需要通过布局管理

     QWidget *widget = new QWidget;

     QHBoxLayout *hLayout;

     hLayout = new QHBoxLayout();

     hLayout->addWidget( label);

     hLayout->addWidget(comBox);

     hLayout->setMargin(0);

     hLayout->setAlignment(widget, Qt::AlignCenter);

     hLayout->setContentsMargins(10, 0, 20, 0);
