Hi Nicolas,

Thanks for your answers.

On the first example from Git - you are right this s= nippet exports correctly. I had a big file and after removing all tables, t= he export failed and I thought it pointed to the git section. But I cannot = duplicate this now, I apologize for including this example.

<= /div>
On the rest of examples that as you said are due to trying to rec= ognize table.el tables: Personally I like the fact tables from Mysql (and p= erhaps other systems) can be pasted directly and in /most cases/ work throu= gh the table.el mechanism. If support for table.el is dropped, is there a w= ay to convert table.el tables to org tables? imho, that would be really hel= pful precondition to dropping the table.el support.

And thanks for the #begin/end_example pointer.

Thanks for your report.

I don't get any error with this example. However, I suggest to w= rap such
things within a verbatim block, e.g., #+begin_example, so they don't interfere with Org syntax.

The three examples describe the same problem. Org has "some&quo= t; support for
"table.el" tables. However, it is very bad at recognizing them: b= oth
examples 3 and 4 are recognized as "table.el" tables.

Worse, "table.el" is bad at recognizing "table.el" tabl= es.=A0 Hence,
example 2 is /almost/ a "table.el" table, but "table.el"= ; itself fails to
correctly recognize it.

So, even if we improve Org to recognize them better (and there's
definitely room for that), we cannot do better than the concerned
library itself, which is not perfect either.

IMO, it is worth pondering if we should drop the defective support for
table.el tables in Org.

In the meanwhile, you can also wrap this kind of output in a verbatim
block or a fixed-width area.
