横向表格超出页面边框

Question

我有一个问题。我想在 Latex 中显示我的数据集。我只想给出一小段摘录。只有几列。问题是它们对于页面来说太长了。我试过减小字体大小。但那不起作用。还有其他选项可以显示整个列而不超出页面边框吗？

\documentclass[12pt]{report}
\usepackage[usegeometry]{typearea}% load before geometry
\usepackage[a4paper, left={2.5cm}, right={2cm}, top={3cm}, bottom={3cm}, headheight=15pt]{geometry}
\usepackage{filecontents}
\usepackage[ngerman]{babel}
\usepackage{tabularx}

\usepackage{fancyhdr}
\usepackage{lipsum}% just to generate text for the example

\usepackage{tabularx}
\usepackage{caption}
\captionsetup[table]{position=bottom}

\fancypagestyle{plain}{%
  \fancyhf{}%
  \fancyhead[L]{\nouppercase{\leftmark}}%
  \fancyfoot[R]{\thepage}}
\pagestyle{plain}
\renewcommand{\chaptermark}[1]{\markboth{\thechapter. #1}{}}
\usepackage[parfill]{parskip}


\usepackage[toc,page]{appendix}
\usepackage{float}
\usepackage{pdflscape}

\begin{document}
