[Docutils-develop] [docutils:bugs] #440 longtable labels in the wrong place

[Erik H. <eri...@us...>]

I've attached the sample table I've used. See `tables.rst`. I did use the `--reference-label ref` option to get table numbers in the references. The attached `run.sh` shows how I've run the tools.

The standard named references work fine with the `\label` after the `\end{longtable}`.  When using `\ref{}` to refer to tables however, no number shows. This only seems possible when the `\label{}` is moved near the caption or inside table body. See `tables_edited.tex` for how I'v manually edited the tex file to make it work. That is, if the table has a caption it works. For some reason I haven't been able to place a `\label{}` inside a table without a caption.

Haven't run the docutils test suite.

I guess this whole ticket boils down to how can we get numbered tables references to work?

The latex2e writer outputs `\label{}` for tables after `\end{longtable}`. This is incorrect causing the table referencing to end up with empty reference text rather than the table number. The author of the `longtable` latex package suggest putting the `\label{}` inside the caption itself  `\caption{My caption \label{mylabel}}` or inside the table body. The latter option has the added benefit of working for tables without  a caption. I've attached a proposed fix.

`longtable` package documentation can be found at https://mirror.ox.ac.uk/sites/ctan.org/macros/latex/required/tools/longtable.pdf. See page 4 and 5 about the discussion on labeling.
