I'm trying to use 'sideways' with an org-mode table being exported to
latex. But its not working. This is my table header -

--8<---------------cut here---------------start------------->8---
#+CAPTION: Table of Parochial Fees from 1 January 2017 - Funerals, Burials and Monuments (cite:0204).
#+ATTR_LATEX: :booktabs t :environment longtable :float sideways
--8<---------------cut here---------------end--------------->8---

If I don't have ':environment longtable' then the pdf compiling fails saying that -

--8<---------------cut here---------------start------------->8---
! LaTeX Error: Environment sidewaystable undefined.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              
                                                  
l.12122 \begin{sidewaystable}
                             [htbp]

--8<---------------cut here---------------end--------------->8---

So how can I use 'sideways' with a table please? Its not clear exactly
what to do from the org-mode manual, and google doesn't provide any
solutions either.

Thanks
Sharon.
