If I export a table with
#+ATTR_LATEX: :environment longtable
#+NAME: mytable
then the beginning of the longtable environment (in the exported
latex file) has, e.g.,
\begin{longtable}{lrrl}
\label{mytable}
\\
\hline
This is a problem, because of the extra space created by the \\. I
tried to fix it by changing ox-latex.el, but the longtable environment
(in latex) requires the \\ when there is a \label{} command, even in the
absence of a caption. This looks like a bug in longtable to me, but it
is also true that in a pure LaTeX context it would be very unusual for a
table to have a \label{} without a \caption{}, because there would be no
printed target for \ref{mylabel} to refer to.
Note that there is no problem if the org table has no NAME, since then
the lines
\label{mytable}
\\
are not produced. But I want the NAME in the org file because because I
use data from the table to do calculations in other tables via
"remote(mytable, ...)".
So my sugggestion would be for org's latex export to produce no \label{}
(and hence no \\) when the table has no caption, or at least I would
prefer to have this as an option. Is there some way to achieve this?
Perhaps I should also file a bug report with the author/maintainer of
longtable, David Carlisle?
One more minor comment: I notice that org-mode's latex export puts the
\label{} inside the argument of the \caption{} command. This seems
unusual to me.

You can use a table filter to remove \label and \\ from longtables. See
(info "(org) Advanced configuration")

Probably.

It isn't wrong, though.

and in fact is common practice!

Thanks. Just to be clear, you are suggesting a filter that would remove
\label and \\ from longtables that have no caption, but that would leave
them in for longtables that do have a caption. Is that right?

Correct.
