[BUG] Clock report produces malformed table when contributed headings contain "|" in their title [9.7-pre (release_9.6.16-1060-g1aa455 @ /home/yantar92/.emacs.d/straight/build/org/)]

[Ihor Radchenko <yantar92@posteo.net>]

 
Consider the following Org file:  #+BEGIN: clocktable :scope file 
:maxlevel 2 #+END: 

* Heading with vertical bar | in its name
:LOGBOOK:
CLOCK: [2018-02-28 Wed 20:28]--[2018-02-28 Wed 22:29] =>  2:01 
:END: 

* Heading without vertical bar \vert in its name
:LOGBOOK:
CLOCK: [2018-02-28 Wed 20:28]--[2018-02-28 Wed 22:29] =>  2:01 
:END:  *  src_elisp{"|"} in its name
:LOGBOOK:
CLOCK: [2018-02-28 Wed 20:28]--[2018-02-28 Wed 22:29] =>  2:01 
:END: 
 

With point at the clock table, press C-c C-c.

Observe:

#+CAPTION: Clock summary at [2024-01-14 Sun 14:53]
| Headline                           | Time           |         |
|------------------------------------+----------------+---------|
| *Total time*                         | *6h 3min*        |         |
|------------------------------------+----------------+---------|
| Heading with vertical bar          | in its name    | 2h 1min |
| Heading without vertical bar \vert in... | 2h 1min        |         |
| src_elisp{"                        | "} in its name | 2h 1min |

Note how the first and last headings produce two table columns instead
of one.

The first heading is relatively easy to fix - we may replace "|" in
title with \vert entity.

Not so easy for src block and other verbatim text - there is simply no
way to escape "|" in tables.
