For `translated_row` show blank translations as "muted / disabled"

[besi]

I am using an entity which has a number of translated fields. So it would be very practical for me to see all the missing attribute - translations at a glance (Fake Screenshot):

What I think would also be a nice addition would be to somehow highlight the currently selected language.

This would be a nice addition. I'll try to implement it in the next few days.
