Okay, I have investigated.  Attached is a simple example which
illustrates the problem which appears to be use of a latex macro within
a table.  Are latex macros still allowed?  I have used emacs -Q and
loaded in the new export etc.  No customisations.

The error message for this example is:

,----

It's the export engine and it's due to my \ref{...} having the \
escaped, which should not happen.
