[PyQt] QTableView set header labels

[HeinKurz]

Problem solfed in table format class:

# table format class
class TableModel(QtCore.QAbstractTableModel):
    def __init__(self, data):
        super(TableModel, self).__init__()
        self._data = data
        #self.rows_nr, self.columns_nr = data.shape
        self.hheaders = ["ID", "Datum", "Gewicht", "Bmkg"]           # <<<<<<<<<<<<<<< NEW LINE

    def data(self, index, role):

        if role == Qt.DisplayRole:
            value = self._data[index.row()][index.column()]

            if index.column() == 2:    # Betrag
                return "%.1f" % float(value)
            #elif index.column() == 1:  # Datum
            #    return value.strftime("%Y-%m-%d")
            else:
                return value

        if role == Qt.TextAlignmentRole:
            value = self._data[index.row()][index.column()]

            if index.column() == 0 or index.column() == 2:   # ID, Betrag
                return Qt.AlignmentFlag.AlignVCenter + Qt.AlignmentFlag.AlignRight
            else:
                return Qt.AlignmentFlag.AlignVCenter


    def rowCount(self, index):
        # The length of the outer list.
        return len(self._data)

    def columnCount(self, index):
        # The following takes the first sub-list, and returns
        # the length (only works if all rows are an equal length)
        return len(self._data[0])

    def headerData(self, section, orientation, role):           # <<<<<<<<<<<<<<< NEW DEF
        # row and column headers
        if role == QtCore.Qt.DisplayRole:
            if orientation == QtCore.Qt.Horizontal:
                return self.hheaders[section]
        return QtCore.QVariant()
