For the record, it is more like

  | a very long entr=E2=80=A6|
  |                 =E2=80=A6|
  |                 =E2=80=A6|

So the narrowing is done field wise and not column wise. If you are in
the last cell, you cannot possibly tell the column is narrowed unless
you check other levels.

There is a misunderstanding here. One of the motivation of the current
implementation of columns narrowing is to _not change the buffer_.  It
hides characters, but never removes them.

So, if you want to remove characters on the right, you need to hide them
somehow. So, I still think you would need to narrow on both sides.
I have the gut feeling this is not very practical.

I agree right-aligned -- and center-aligned -- fields are not perfect,
but I cannot think of a good design for these at the moment.
