    This demo shows a table with key/value pairs. The values can be edited.
    There are two types of values: strings and bools. Dependent of the type,
    either a CellRendererText or CellRendererToggle is used to show and edit
    the value.

    This is done by connecting the visibility of a CellRenderer to a
    ListStore column.

    2018-03-29: ref to issiue #231
    Added colors in first column GdkColor & RGBA.
    This tests ListStore storing more complex attribute, than simple GType.
