Hi there!

It's hard to help you without any information what you've tried doing already.

From a distance, I'd expect it to be tricky to render null as a string like the desired output you've shown, but one trick you could try is to use changed nulls into string's that contains "null" like this recent workaround shows: #766 (comment)
