you can define you own model, deriving from a Qt standard model, 
and override flags(). In the link I gave you there is a file rulesetselector.py
which defines a tree view where some items can be edited in
different ways (combobox, text, numbers, checkboxes). Your table
view should be easier to implement.

    def flags(self, index): # pylint: disable=R0201
        """tell the view what it can do with this item"""
        if not index.isValid():
            return Qt.ItemIsEnabled
        column = index.column()
        item = index.internalPointer()
        content = item.rawContent
        checkable = False
        if isinstance(content, Ruleset) and column in (0, 3):
            mayEdit = True
        elif isinstance(content, Rule):
            mayEdit = column in [0, 1, 2, 3]
            checkable = column == 1 and content.parType is bool
        else:
            mayEdit = False
        mayEdit = mayEdit and not isinstance(item.ruleset(), PredefinedRuleset)
        result = Qt.ItemIsEnabled | Qt.ItemIsSelectable
        if mayEdit:
            result |= Qt.ItemIsEditable
        if checkable:
            result |= Qt.ItemIsUserCheckable
        return result
