Syntax for COLUMN reference in Table


I'm failing to do something seemingly basic. I have a column "MyModel -> Number", its shown in a table because of a grouping i've made so it is a joined in value.

I'm trying to use it to create a link in a column


But I cannot figure out the syntax.. {{ Number }}, does not work, neither does {{ MyModel.Number }} or {{ MyModel -> Number }}

What am I doing wrong?

Doh. Rubber-ducking this one.

I added explicit join columns instead of relying on using the data model. And now {{NUMBER}} works fine.
