including the | character in a table

including the | character in a table

Hello,

I'm writing a cheat sheet for a programming language, and I'm having
trouble with operators that use |. For instance:

| match expr with   | pattern matching |
| | pattern -> expr | action           |

How can I escape the |? I tried putting a \ before but it does not work.

Thanks,

Alan

I've used macros in the past for such a case. Quite heavyweight, but I didn't find anything better. Here is an example (which you could augment if you wanted to export to LaTeX too):

#+MACRO: I @@html:|@@

| match expr with        | pattern matching |
| {{{I}}}pattern -> expr | action           |

You can use \vert to insert pipes in exported tables.

Thank you Michel and Kevin for these proposals. \vert works great (as
long as it's outside ~~, but I can deal with it).

Thanks!

No problem, I actually just ran into the need to do this yesterday so your
question was very timely.
