I'm having great difficulty in getting my tables to show up in
'\listoftables', the 'Table' header shows in my pdf but nothing else
related to tables in the preamble after the TOC.

Taking this table as an example -

--8<---------------cut here---------------start------------->8---
#+LABEL: tab:table1
#+NAME: tab:table1
#+CAPTION: Previous versions of this document
#+ATTR_LATEX: :booktabs t :placement [H]
| *Title*                   | *Version* | *Published*     |
|-------------------------+---------+---------------|
| Hormones 2016           |     1.5 | May 2016      |
| Hormones 2017           |     1.6 |               |
--8<---------------cut here---------------end--------------->8---

Which is exported to latex as this -

--8<---------------cut here---------------start------------->8---
\section{Previous versions}
\label{sec:orgd5daa04}
\begin{table}[H]
\centering
\begin{tabular}{lrl}
\toprule
\textbf{Title} & \textbf{Version} & \textbf{Published}\\
\midrule
Hormones 2016 & 1.5 & May 2016\\
Hormones 2017 & 1.6 & \\
\bottomrule
\end{tabular}
\caption{\label{tab:org2f5a19c}
Previous versions of this document}

\end{table}
--8<---------------cut here---------------end--------------->8---

I am using my own latex-class called 'my-report' which is like this in
my config.org -

--8<---------------cut here---------------start------------->8---
(with-eval-after-load 'ox-latex
(add-to-list 'org-latex-classes
             '("my-report" "\\documentclass{report}
               [NO-DEFAULT-PACKAGES]"
               ;;[EXTRA]"
               ;;("\\part{%s}" . "\\part*{%s}")
               ("\\chapter{%s}" . "\\chapter*{%s}")
               ("\\section{%s}" . "\\section*{%s}")
               ("\\subsection{%s}" . "\\subsection*{%s}")
               ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
               ("\\paragraph{%s}" . "\\paragraph*{%s}")
               ("\\subparagraph{%s}" . "\\subparagraph*{%s}"))))
              ;; (custom-set-variables '(org-export-allow-bind-keywords t))
--8<---------------cut here---------------end--------------->8---

And here is my main preamble -

Can anyone please help me to get '\listoftables' working please, I just
feel like I'm going round in circles at the moment and not achieving
anything, and its so frustrating

Thanks
Sharon.
