[O] Keeping vertical bars in exported, ASCII file

[Michael Hannon]

Greetings.  I wonder if there's a way to tell Emacs to keep the "fences"
(vertical bars) in an exported, ASCII file.  I.e., sometimes I'd like:

    | Name  | Phone | Age |
    |-------+-------+-----|
    | Peter |  1234 |  17 |
    | Anna  |  4321 |  25 |

instead of:

      Name    Phone   Age 
     -------+-------+-----
      Peter    1234    17 
      Anna     4321    25 

Is there some way to do that?

I've tried:

    #+OPTIONS |:t
    #+OPTIONS ::t
    #+OPTIONS |:t ::t

but didn't notice any change in the output.

Thanks,
