How to word wrap the header contents of QTableWidget in PyQt5 Python

Question

I am working on PyQt5 where I have a QTableWidget. It has a header column which I want to word wrap. Below is how the table looks like:

As we can see that the header label like Maximum Variation Coefficient has 3 words, thus its taking too much column width. How can wrap the words in the header.

Below is the code:

import sys

from PyQt5 import QtWidgets
from PyQt5.QtWidgets import *


# Main Window
class App(QWidget):
    def __init__(self):
        super().__init__()
        self.title = 'PyQt5 - QTableWidget'
        self.left = 0
        self.top = 0
        self.width = 300
        self.height = 200

        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)

        self.createTable()

        self.layout = QVBoxLayout()
        self.layout.addWidget(self.tableWidget)
        self.setLayout(self.layout)

        # Show window
        self.show()

    # Create table
    def createTable(self):
        self.tableWidget = QTableWidget()

        # Row count
        self.tableWidget.setRowCount(3)

        # Column count
        self.tableWidget.setColumnCount(2)

        self.tableWidget.setHorizontalHeaderLabels(["Maximum Variation Coefficient", "Maximum Variation Coefficient"])
        self.tableWidget.setSizeAdjustPolicy(QtWidgets.QAbstractScrollArea.AdjustToContents)
        self.tableWidget.horizontalHeader().setSectionResizeMode(QHeaderView.ResizeToContents)

        self.tableWidget.setItem(0, 0, QTableWidgetItem("3.44"))
        self.tableWidget.setItem(0, 1, QTableWidgetItem("5.3"))
        self.tableWidget.setItem(1, 0, QTableWidgetItem("4.6"))
        self.tableWidget.setItem(1, 1, QTableWidgetItem("1.2"))
        self.tableWidget.setItem(2, 0, QTableWidgetItem("2.2"))
        self.tableWidget.setItem(2, 1, QTableWidgetItem("4.4"))

        # Table will fit the screen horizontally
        self.tableWidget.horizontalHeader().setStretchLastSection(True)
        self.tableWidget.horizontalHeader().setSectionResizeMode(
            QHeaderView.Stretch)


if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())

I tried adding this self.tableWidget.setWordWrap(True) but this doesnt make any change. Can anyone give some good solution. Please help. Thanks

EDIT:

Also tried this :

self.tableWidget.horizontalHeader().setDefaultAlignment(QtCore.Qt.AlignHCenter | Qt.Alignment(QtCore.Qt.TextWordWrap))

But it didnt worked
