Well, the user could edit the visible column. On doing so the invisible column would need to be updated with the corresponding parse-able value of the just entered value.
IIUC you want the visible column to be a translated name. As I said above, there is no way of un-translating strings available to my knowledge, so the "updating" is not a simple thing.
(can't even send the text to google translate to convert it, "Umschalt s" comes back as "Switch s" *sigh*)
