Yes thanks, I deliberately left those out, but they are working fine (as I
know by having debug output to my log window) and looks like below. I also
have headerData(). My header is showing up just fine by the way. The
vertical header is not shown, even if I set it to be shown, which is strange
because both rows and columns are returned properly:

    def rowCount(self, index=QModelIndex()):
        return len(self.uncertainties)

    def columnCount(self, index=QModelIndex()):
        return len(Uncertainty.uncertaintyAttrList)

    def headerData(self, col, orientation, role):
        if orientation == Qt.Horizontal and role == Qt.DisplayRole:
            return Uncertainty.uncertaintyAttrList[col]
        return None
