from PySide2.QtCore import Qt
from PySide2.QtWidgets import QMainWindow, QTableWidgetItem


class CMTableWidgetItemNonEditable(QTableWidgetItem):
    """Unset editing flags
    """

    def __init__(self, *args, **kwargs):

        self.setFlags(self.flags() & ~Qt.ItemIsEditable)


class MainWindow(QMainWindow):
    # ⋮ Lot of other stuff here
    def update_table(self, data):
        logger.debug("data=%r", data)
        for row, (name, value) in enumerate(data.items()):
            # Data come in bytes 
            name, value = name.decode("utf-8"), value.decode("utf-8")

            self.readerInfoTable.insertRow(row)
            
            item_1 = CMTableWidgetItemNonEditable(name)
            item_2 = CMTableWidgetItemNonEditable(value)
            
            self.readerInfoTable.setItem(row, 0, item_1)
            self.readerInfoTable.setItem(row, 1, item_2)
