Getting rid of whitespace in a QTableWidget

[di_zou]

I have a QTableWidget. The image attached is what it looks like. How do I make it so that when the dialog first starts up, I want it so that the dialog is only wide enough to show the two columns? I also want to make the QTableWidget shorter to get rid of the whitespace underneath the rows. Is there a setting or function I can use for that? This is what I have in the dialog init function. It is in python, but it is fairly equivalent to the C++ code.

self.displayText = QTextEdit(self)
self.labelTable = QTableWidget(1, 2, self)
 
self.acceptButton = QPushButton(self)
self.acceptButton.setText("Accept")
 
self.cancelButton = QPushButton(self)
self.cancelButton.setText("Cancel")
 
buttonGridLayout = QGridLayout()
buttonGridLayout.addWidget(self.acceptButton, 0, 0, Qt.AlignLeft)
buttonGridLayout.addWidget(self.cancelButton, 0, 1, Qt.AlignLeft)
 
gridLayout = QGridLayout()
gridLayout.addWidget(self.labelTable, 0, 0)
gridLayout.addWidget(self.displayText, 1, 0)
gridLayout.addLayout(buttonGridLayout, 2, 0)
 
self.setLayout(gridLayout)
 
labels = QStringList()
labels << "Type" << "Name"
 
self.labelTable.setHorizontalHeaderLabels(labels)

self.displayText = QTextEdit(self)
self.labelTable = QTableWidget(1, 2, self)
        
self.acceptButton = QPushButton(self)
self.acceptButton.setText("Accept")
        
self.cancelButton = QPushButton(self)
self.cancelButton.setText("Cancel")
        
buttonGridLayout = QGridLayout()
buttonGridLayout.addWidget(self.acceptButton, 0, 0, Qt.AlignLeft)
buttonGridLayout.addWidget(self.cancelButton, 0, 1, Qt.AlignLeft)
                
gridLayout = QGridLayout()
gridLayout.addWidget(self.labelTable, 0, 0)
gridLayout.addWidget(self.displayText, 1, 0)
gridLayout.addLayout(buttonGridLayout, 2, 0)
        
self.setLayout(gridLayout)
                
labels = QStringList()
labels << "Type" << "Name"
        
self.labelTable.setHorizontalHeaderLabels(labels)

To copy to clipboard, switch view to plain text mode 

Also, How do I make the cells not editable?
