Show via checkbox in a screen table if an entity attribute is filled

Hi there,
I have a screen table that needs to show a checkbox that indicates if an entity attribute (type date) is empty or not.
Is there a (simple) way to do so?

Thanks for any hints!

Hi,

  1. You can do this by adding a generated column to the table:

  2. You can a Boolean meta-property (non-persistent property) to the entity displayed in the table, and implement logic in the getter.

Ok, thanks. I found that meanwhile.
If that’s the possible and recommended way, I’ll do so.
