PyQt6, QTableView - How can I change the column headings?

PythonQTMarlem

Hello,
this is my code:

import sys
from PyQt6 import QtGui
from PyQt6.QtSql import QSqlDatabase, QSqlRelation, QSqlTableModel
from PyQt6.QtWidgets import QWidget, QApplication, QFormLayout, QTableView


class FensterKlasse(QWidget):
    def __init__(self):
        super().__init__()
        self.table_model = QSqlTableModel()
        self.table_model.setTable("telefon_verwaltung")
        self.table_model.select()
        self.GUI()

    def GUI(self):
        self.setWindowTitle("PyQt6 Telefonnummer-Verwaltung mit Datenbank")
        self.setGeometry(0,0,500,500)
        qtRectangle = self.frameGeometry()
        centerPoint = QtGui.QGuiApplication.primaryScreen().availableGeometry().center()
        qtRectangle.moveCenter(centerPoint)
        self.move(qtRectangle.topLeft())

        self.tabellengrid = QTableView()
        self.tabellengrid.setModel(self.table_model)
        self.tabellengrid.setColumnWidth(0,2)
        self.tabellengrid.setColumnHidden(0,True)
        self.tabellengrid.setColumnWidth(1, 100)
        self.tabellengrid.setColumnWidth(2, 150)
        self.tabellengrid.setColumnWidth(3, 130)

        formLayout = QFormLayout()
        formLayout.addRow(self.tabellengrid)
        self.setLayout(formLayout)


def programm_beeden(self):
    QApplication.instance().quit()


app = QApplication([])
db = QSqlDatabase.addDatabase("QSQLITE")
db.setDatabaseName("telefonnummern_verwaltung.db")

fenster = FensterKlasse()

if __name__ == '__main__':
    fenster.show()
    sys.exit(app.exec())

Question:
How can I change QTableView's column headings?

@PythonQTMarlem
You do that at the model side, that is where QTableView gets its data from. You could subclass QSqlTableModel and override headerData(), or call setHeaderData() [without needing to subclass]. Examples at https://stackoverflow.com/questions/64287713/how-can-you-set-header-labels-for-qtableview-columns.
