I want to manage some perl regexps in a table
then feed them to a code block (literate programming).
Unfortunately they include alternatives (|)
and the table editor thinks this is a column break.
There's no way to escape this?
On a related thought: what is the best way to manage
leading/trailing spaces in a table cell?
I've been forced to use \x20 for this purpose...

AFAIK, there is not.

This i don't understand -- you want to *keep* the spaces
in the exported table?

Shouldn't your perl regexp be in a formula - ie. not directly in the table ?

Not all spaces, but some spaces some of the time is needed.
The recent patch to org-babel-read by Erik Schulte makes this possible. See second sentence below:
If a value starts with one of ('` it is read as an emacs lisp sexp.
If it starts with " then it's read as a quoted string: start/end quotes are stripped, \" and \\ are unescaped
(this is useful for embedding leading/trailing whitespace in strings).
If it looks like a number, it's read as a number.
Else it's read as a literal string, without any quotation or escaping.
(Please note that | in tables is always interpreted as column separator and currently there is no way to quote it)

Using a different character (namely ¦) the following should work
#+source: clean
#+begin_src emacs-lisp :var in=""
(flet ((clean (in)
(if (listp in)
(mapcar #'clean in)
(if (stringp in)
(replace-regexp-in-string "¦" "|" in)
in))))
(clean in))
#+end_src
#+results: regexps
| first | (a¦b) |
| second | (1¦2) |
#+begin_src perl :var a=clean(in=regexps)[0,1] :var b=clean(in=regexps)[1,1]
$a; $b;
#+end_src
#+results:
: (1|2)
