How to rotate a Markdown table to landscape? Solutions I've tried print the markup instead of the rendered table

Question

I'm using Markdown to create a PDF via xelatex and pandoc. Here's my command line:

pandoc -s combined.markdown --from markdown+table_captions+auto_identifiers --filter mermaid-filter.cmd --pdf-engine=xelatex -o combined.pdf

My document contains the following table:

Table: Groups and Access Rights - Global



  
Group Name
  
Type
  
Config / Func
  
Default Act
  
Reqs
  
Derog
  
ADC
  
Haz
  
Chg
  
BS
  
Risks
  
MMSP Status




  
CPxxx Risk Managers
  
\gls{ps}
  
X
  
CPxxx Home
  

  

  

  

  

  

  

  




(etc)

It's very wide, so I want to render it in landscape. I've tried using {rotating}, {lscape}, and {pdflscape}, but they all look like this:

Is there any way to make this work? Is it something to do with the order of packages?

Answer 1

I found following solution:

---
title: "Doc-Title"
lang: "de"
colorlinks: true
header-includes:
- |
  ```{=latex}
  \usepackage{pdflscape}
  \newcommand{\blandscape}{\begin{landscape}}
  \newcommand{\elandscape}{\end{landscape}}
    ```
...

in your markdown use:

    \blandscape
|header1|header2|header3|
|:------|:------|------:|
|LINE1  | VAL 1 |  1.00 |
|Line2  | val 2 |  2.07 |
|Line3  | val 3 |  3.14 |

\elandscape

Answer 2

You can use LaTeX chunks inside Markdown, but not markdown inside LaTeX.

In the markdown to LaTeX conversion, what it is inside a command argument or an LaTeX environment is simply ignored (On the other hand, note that the Markdown table is converted to a LaTeX longtable, that could not be used in some conditions (e.g., in two columns documents).

One solution could be first export only the Markdown table and then copy & paste (or \input) the LaTeX code (of the longtable only) in the rotating environment.

Other, more convenient, is to write the nesting environment with the Markdown syntax:

---
output:
  pdf_document: default
header-includes:  
- \usepackage{lscape}  
---
::::::::{.landscape data-latex=""}
11 12 13

21 22 23
31 32 33
::::::::

Removing irrelevant code in the LaTeX output, the above should be equivalent to:

\documentclass{article}
\usepackage{lscape,longtable,booktabs}
\begin{document}
\begin{landscape}
\begin{longtable}[]{@{}lll@{}}
\toprule
11 & 12 & 13\tabularnewline
\midrule
\endhead
21 & 22 & 23\tabularnewline
31 & 32 & 33\tabularnewline
\bottomrule
\end{longtable}
\end{landscape}
\end{document}
