This question continues my another:
I found several suggestion here on TeX - LaTeX Stack Exchange (1, 2, 3...). But I don't know which is more suitable for my case.
MWE:
\documentclass[
usegeometry = on,
DIV = calc,
french,
english,
ngerman
]{scrartcl}
\usepackage[onehalfspacing]{setspace}
\usepackage[
left = 25mm,
bottom = 20mm,
right = 45mm,
top = 20mm,
includehead,
heightrounded
]{geometry}
\usepackage[singlespacing]{scrlayer-scrpage}
\ForEachLayerOfPageStyle*{scrheadings}{%
\ifstrstart{#1}{scrheadings.foot}
{
\ModifyLayer[
voffset = \paperheight - 2\baselineskip,
align = b
]{#1}
}
{}%
}
\AfterTOCHead{\singlespacing}
\usepackage[T1]{fontenc}
\usepackage{
showframe,
babel,
filecontents,
csquotes,
pdflscape,
tabularx
}
\usepackage[
backend = biber,
sortlocale = auto,
sorting = nyt,
style = ext-authoryear-comp
]{biblatex}
\newcommand*\english[1]{\foreignlanguage{english}{#1}}
\begin{filecontents*}{\jobname.bib}
@MVREFERENCE{Janes,
EDITOR = {\english{Jane's}\textsuperscript{\textregistered}},
LOCATION = {\english{Coulsdon, Surrey} (GB)},
PUBLISHER = {IHS Markit},
DATE = {2017},
EDITION = {2017--2018},
SUBTITLE = {\english{Development \& Production}},
TITLE = {\english{All the World's Aircraft}},
}
\end{filecontents*}
\addbibresource{\jobname.bib}
\begin{document}
Text.
\begin{landscape}
\begin{table}
\centering
\caption{Übersicht über den Einsatz des Triebwerks PW1000G}
\begin{tabularx}{\linewidth}{cccXc}
Hersteller & Flugzeugbezeichnung & Entwicklungsland/Region & aktueller Entwicklungsstand & Quelle\\
\english{Airbus} & A319neo/320neo/321neo & Europa & Liniendienst, Stand 25.~Januar 2016 & \autocite[338]{Janes}\\
\foreignlanguage{french}{Bombardier} & \english{C-Series} & Kanada & Liniendienst, Stand 31.~Dezember 2016 & \autocite[101]{Janes}\\
Mitsubishi & MRJ & Japan & erste Auslieferung Mitte 2020 geplannt, Stand 23.~Januar~2017 & \autocite[501]{Janes}\\
Irkut & MS-21 & Russische Föderation & erste Auslieferung Ende 2018 geplant, Stand 8.~Juni 2016 & \autocite[567]{Janes}
\end{tabularx}
Quelle: Eigene Darstellung nach \autocite[101, 338, 501 und 567]{Janes}.
\end{table}
\end{landscape}
Text.
\end{document}
The result (page one):
and (page two):
Why is it so? What is to do? I'am open for any suggestion. For example to redesign the layout or to optimize the table in such way that I can skip the landscape layout for the page with the table.
Thank you for your help and effort in advance!
