Hi @Tess,
Thanks for replying!
This is what I meant by generated column:
I actually tried again with removing the source id (and using currentsourcerow for the value {{new Date().getFullYear() - new Date(currentSourceRow.createdAt).getFullYear()}}
, and now it does seem to work.
This is what happens if you leave the source ID in the column:
Every time you move that column and refresh it clones itself and you end up having doubles, triple etc. Don't try to do it in edit mode because then your table gets messed up and you have to delete all of the columns like that which you reordered... learned the hard way.
I think my table was messed up from doing it with the sourceId and thats why I thought it didnt work.
