splitter = new QSplitter(Qt::Vertical);   //QSplitter是用来分割窗口的
    proFieldTable = new QTableView;
    mdiArea = new QMdiArea;
    
    splitter->addWidget(proFieldTable);
    splitter->addWidget(mdiArea);
    splitter->setStretchFactor(0, 0);        
    splitter->setStretchFactor(1, 1);

    proFieldTable->setModel(proFieldModel);  
    proFieldTable->setEditTriggers(QAbstractItemView::NoEditTriggers);

    QItemSelectionModel *selectionModel = new QItemSelectionModel(proFieldModel);
    proFieldTable->setSelectionModel(selectionModel);

    setWidget(splitter);
