[PyQt] Qtableview adapte size to

[WBPYTHON]

Hello,

Is it possible to adapte the size of a Qtableview to the main window ? when I pull the window on the right side, I would like the Qtableview to adapt and expand horizontaly. But I don't want it to fill ALL the main window.

I have this :

When I pull the window on the right, it should horizontaly adjusts:

But at the moment it does nothing:

So I tried many codes with QHboxLayout and other, but nothing works, the last I tried was this for instance:

      def initUI(self):
        self.statusBar()

        menubar = self.menuBar()
        fileMenu = menubar.addMenu('File')
    
        self.centralwidget = QWidget(self)
        self.horizontalLayoutWidget = QWidget(self.centralwidget)
        self.horizontalLayoutWidget.setGeometry(30, 10, 721, 171)
        self.horizontalLayout = QHBoxLayout(self.horizontalLayoutWidget)
        self.horizontalLayout.setContentsMargins(0, 0, 0, 0)
        self.widget = QWidget(self.horizontalLayoutWidget)
        self.table_view = QTableView(self.widget)
        
        self.model = pandasModel(df)

        self.table_view.setModel(self.model)
        self.table_view.show()
        self.table_view.resizeColumnsToContents()
        
        self.setCentralWidget(self.centralwidget)
        self.resize(800, 600)  
        self.setWindowTitle('test')
        
    
        self.show()

But the result is even worse.



Thank you in advance for you help.
