The hyperref package provides a LaTeX solution, the briefest of which is 
the \url{} command (and the \nolinkurl{} variant).
   #+ATTR_LaTeX: align=llp{2cm}
  | ITEM             | Comment                   | e-mail                                  |
  |------------------+---------------------------+-----------------------------------------|
  | ~url~ cmd        | e-mail is a dead link     | \url{this.email@shouldbe.wrapped}       |
  | ~nolinkurl~ cmd  | e-mail is just text       | \nolinkurl{this.email@shouldbe.wrapped} |
  | ~mailto:~ syntax | e-mail is an mailto: link | mailto:this.email@shouldbe.wrapped      |

*** Notes for the mailto syntax
For the ~mailto:~ syntax to work the variable
~org-export-latex-href-format~ needs to use the ~url~ command instead of
~href~ (http://article.gmane.org/gmane.emacs.orgmode/44911/match=href+latex+link+url)
: (setq org-export-latex-href-format "\url{%s}") 

While I prefer the ~mailto:~ syntax as more the `orgmode way', there are
two possible issues:
 - config :: It requires a change to *all* LaTeX link exports
 - display :: The ~mailto:~ string is also exported
I do not know what other solutions are currently possible to resolve those
issues.
