How do I force a folder to be opened in column view in Finder?
Workaround


While in Finder (in any view) drag the Column_Folder/ to the Finder's sidebar.
Select the Column_Folder/ from the sidebar
Switch to column view
Show view settings

You can see the view settings will now affect the intended folder

Tick "Always open in column view"; click OK
Remove Column_Folder/ from the sidebar


Now Column_Folder/ will open in column view!
