Qtableview margin/padding

[Zoner]

Hi Team

I have a small problem with tableview.
The problem I have is that the QT designer view and the actual application view differ (as shown in the in the pic below).
The table is somehow split in two columns, but when populating all data appears on the left side, including scroll bars.
After import of my data, these views stay the same. My data appears in the left field (with scroll adjuster) whilst the right field stays blank.

Does anybody know what setting may need to change in QTdesigner (or in my code) to resolve this?

from PyQt5 import QtCore, QtWidgets, uic
from PyQt5.QtCore import Qt
from PyQt5.QtGui import *
from PyQt5.QtWidgets import (qApp, QComboBox, QMainWindow, QApplication, QMessageBox, QFileDialog)
 
#define class
class Bathyui(QtWidgets.QDialog):
    def __init__(self, parent=None):
        super(Bathyui, self).__init__(parent)
        uic.loadUi('Open_File_UWN_Model.ui', self)
 
#connect to widget
        self.table = QtWidgets.QTableView(self.tableView)
 
#populate with dataframe
        self.table.setModel(file_reader)

from PyQt5 import QtCore, QtWidgets, uic
from PyQt5.QtCore import Qt
from PyQt5.QtGui import *
from PyQt5.QtWidgets import (qApp, QComboBox, QMainWindow, QApplication, QMessageBox, QFileDialog)

#define class
class Bathyui(QtWidgets.QDialog):
    def __init__(self, parent=None):
        super(Bathyui, self).__init__(parent)
        uic.loadUi('Open_File_UWN_Model.ui', self)

#connect to widget
        self.table = QtWidgets.QTableView(self.tableView)

#populate with dataframe
        self.table.setModel(file_reader)

To copy to clipboard, switch view to plain text mode

Im a littlebit lost how to solve this. I pretty much hit every setting in the QT Designer formatting menu.
Im using anaconda python with qt designer 5.11.1 included

For one thing, why are you not using layouts for such a complex form? It looks like you have put every widget in place with absolute size and positioning. This will almost certainly result in headaches if you resize the window or deploy it on a PC with different default magnification. Other than that bad problem, I don't see anything wrong with your UI file.

I am not a Python expert, but isn't line 13 creating a second QTableView using the current self.tableView as its parent? This is probably why you are seeing two tables. The left-hand table is this new one, which is getting filled from your model, while the original table created from the UI file is underneath it and in the size you specified in the UI file.

Get rid of line 13 and in line 16 use "self.tableView" to set the model.

That was indeed the solution, and it looks like I need to go down the same road for some pyvistaqt graphs.
I reckon Im still struggling with the widgets.

Thanks for the tip with the layout form, I wondered why I couldnt read it right on my laptop, another one to add to my reading list.

thanks d_stranz
really appreciated!
