import sys
from PyQt5.QtWidgets import QApplication, QTableWidget, QStyledItemDelegate

class ReadOnlyDelegate(QStyledItemDelegate):
    def createEditor(self, parent, option, index):
        print('createEditor event fired')
        return 

class AppDemo(QTableWidget):
    def __init__(self):
        super().__init__(5, 5)
        self.resize(1500, 1500)

        for i in range(5):
            self.setColumnWidth(i, 250)
            self.setRowHeight(i, 100)

        delegate = ReadOnlyDelegate(self)
        self.setItemDelegateForRow(1, delegate)
        self.setItemDelegateForColumn(0, delegate)

app = QApplication(sys.argv)
demo = AppDemo()
demo.show()
sys.exit(app.exec_())
