Как динамически заполнить QTableWidget?

import sys
from PySide2 import QtWidgets, QtCore
 
DATA = [
    [1, 2, 3, 4, 5, 6],
    [4, 5, 6, 7, 8, 9]
]
 
 
class Table(QtWidgets.QTableView, QtCore.QAbstractTableModel):
 
    def __init__(self, parent: QtWidgets.QWidget = None):
        QtWidgets.QTableView.__init__(self, parent)
        self.horizontalHeader().setSectionResizeMode(QtWidgets.QHeaderView.Stretch)
 
        QtCore.QAbstractTableModel.__init__(self, parent)
        self.setModel(self)
 
    def rowCount(self, parent: QtCore.QModelIndex = ...) -> int:
        return len(DATA)
 
    def columnCount(self, parent: QtCore.QModelIndex = ...) -> int:
        return 6
 
    def data(self, index: QtCore.QModelIndex, role: QtCore.Qt.ItemDataRole = ...) -> any:
        if role == QtCore.Qt.DisplayRole:
            return DATA[index.row()][index.column()]
 
    def headerData(self, section: int, orientation: QtCore.Qt.Orientation, role: int = ...) -> any:
        if role == QtCore.Qt.DisplayRole:
            return section + 1
 
 
if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    main = Table()
    main.show()
    sys.exit(app.exec_())
