Would love to be able to freeze columns in the data source. This would make it much easier for troubleshooting data issues.
What do you mean exactly? Preventing data from being written/changed in specific fields?
I don’t want to speak for @Brandi_Bullock but I think they mean freezing/pinning the column so that it’s always on the left when you scroll across the table in the data table/admin view of your tables.
@Brandi_Bullock - it’s something we’re very aware of, and hoping to tackle soon
Of course, that makes sense. And yes, +1 on this one
Yep- that’s exactly what I meant by this Darragh! 
Thanks for the update!
Any update on this feature request? Ran into it again today with a client who wants to freeze 2 columns.
Coming very soon @sydney with a new look to our tables!
