PyQt垂直布局按钮堆叠

Question

我正在尝试为我的一个路由器配置器创建一个GUI。我在QtDesigner中创建了以下窗口

对话框布局是垂直布局

pyuic5生成以下输出

        self.verticalLayout.setObjectName("verticalLayout")
        self.label = QtWidgets.QLabel(Dialog)
        self.label.setObjectName("label")
        self.verticalLayout.addWidget(self.label)

        self.tableWidget.setRowCount(0)
        self.tableWidget.setColumnCount(0)
        self.tableWidget.setObjectName("tableWidget")
        self.verticalLayout.addWidget(self.tableWidget)
        self.horizontalLayout = QtWidgets.QHBoxLayout()
        self.horizontalLayout.setObjectName("horizontalLayout")
        self.label_2 = QtWidgets.QLabel(Dialog)
        self.label_2.setAlignment(QtCore.Qt.AlignLeading|QtCore.Qt.AlignLeft|QtCore.Qt.AlignTop)

        self.horizontalLayout.addWidget(self.label_2)

        self.pushButton.setObjectName("pushButton")
        self.horizontalLayout.addWidget(self.pushButton)
        self.verticalLayout.addLayout(self.horizontalLayout)
        self.pushButton_3 = QtWidgets.QPushButton(Dialog)
        self.pushButton_3.setObjectName("pushButton_3")
        self.verticalLayout.addWidget(self.pushButton_3)
        self.pushButton_3.raise_()
        self.tableWidget.raise_()
        self.label_3.raise_()
        self.label.raise_()

        self.retranslateUi(Dialog)
        QtCore.QMetaObject.connectSlotsByName(Dialog)

    def retranslateUi(self, Dialog):
        _translate = QtCore.QCoreApplication.translate
        Dialog.setWindowTitle(_translate("Dialog", "Router Configurator"))
        self.label.setText(_translate("Dialog", "Project Number"))
        self.lineEdit.setToolTip(_translate("Dialog", "Projekt Nummer eingeben"))
        self.pushButton_2.setText(_translate("Dialog", "Download"))
        self.label_3.setText(_translate("Dialog", "Found Setup"))
        self.label_2.setText(_translate("Dialog", "Directory"))
        self.pushButton.setText(_translate("Dialog", "Change Directory"))
        self.pushButton_3.setText(_translate("Dialog", "Generate Config"))

运行程序时，按钮显示为堆叠在一起，而不是垂直排列。
