The solution in my mind for the small screen is very simple:

-in portrait mode no columns

-when the iphone rotates in landscape mode along with the outline appears one column. If the document has many columns the user can scroll with a touch gesture and see the rest of the columns one by one (in any given moment will be only one column visible).

-no need for advance styling (personally I'm ok with just plain text)
-no attachments, just a placeholder to remind that there is a file in that row
