Yes, you're returning QVariants containing empty strings when you mean
to return invalid QVariants. Change all occurrences of QVariant('') to
QVariant() and it should work as you expect.

It should just work. There are some subtleties with expanding columns
and rows to optimize the space allocated to items - just ask again if
you encounter problems along those lines.
