Relational Column display conditions

[tjhunkin-inhance]

How do I show a column where if the nickname is filled in display that, if not, display a concat of name and surname for a related table?

So if you use a format() callback, you can do that in there.

If you share the current code for your Column, I'll give you some pointers.

I'm more active on the Discord than on here, so feel free to nudge me on there!

probably in conjunction with

$this->setAdditionalSelects(['users.id as id']);
