Graphics, Figures & Tables ⇒ Rotate longtable

[Latex Noob]

Hey there!

I have a couple of tables that are both too wide for portrait and too long to fit on one single page. I used to utilize the landscape environment to rotate tables, but I don´t like that this also rotates the section titles, as this is quite unhandy when flipping through the hardcopy version (of course with the digital PDF this is no problem). Thus, I started to use the \rotatebox{90} command. And it works beautifully for one sided tables, but somehow not for longtables. Does someone know how I can make the rotatebox-command work for longtables or can suggest an alternative solution?

Here is my example:

(Note: Since in an earlier post of mine, my code did not work with other users, I included all preamble entries)

\documentclass[12pt, a4paper, toc=flat] {scrartcl}

\usepackage{anysize}
\marginsize{3cm}{2cm}{2cm}{2cm}
\setkomafont{disposition}{\normalfont\bfseries}
\addtokomafont{chapterprefix}{\huge}
\addtokomafont{chapter}{\Huge}

\renewcommand*{\chapterheadstartvskip}{\vspace*{50pt}}
\renewcommand*{\chapterheadendvskip}{\vspace{40pt}}

\usepackage{etoolbox}

\makeatletter
\patchcmd{\@@makechapterhead}{.5\baselineskip}{20\p@}{}{}
\makeatother

\usepackage[markuppercase]{scrpage2}
\clearscrheadfoot
