Should my custom Cell renderer return null or empty string when no value to format?

[jestrickler]

Any considerations on why the Cell default is ({ value }) => String(value) rather than ({ value }) => (value ? String(value) : null)?

I take the 2nd approach in my custom cell renderers and I think that's typical react logic, but then I was writing tests around some missing data situations and found toBeEmptyDOMElement() was failing with empty string for the default renderer while passing for my renderer. toHaveTextContent('') passes for all which I find odd, you'd think those 2 methods would be simpatico.
