Hey!
Danke eine erste, schnelle Antwort. Natürlich hatte ich das zweite Argument hier vergessen. Die Fehlermeldungen sind jetzt behoben, aber meine "Tabellen-Idee" ist von der Formatierung nicht umgesetzt. Ich zeige euch mal die "Original-Tabelle", damit vielleicht deutlicher wird was mein Problem ist und wieso ich auf diese verschachtelte Konstruktion kam:
\documentclass[12pt,a4paper,onecolumn,oneside,titlepage,headings=small,final]{scrbook}

Sorry, bezüglich des langen Codes. Manchmal sieht man einfach seine Fehler nicht mehr. Lässt man das Problem der letzten \multicolumn{3}{|c|}{....} mal weg. Dann kann man erahnen wie die Tabelle aussehen sollte. Es gibt immer Mal Spalten mir "mulitrow" Inhalt, die mir aber nicht ordenlich umgebrochen werden. Daher versuchte ich an Stelle von multirow, die Problematik mit den angrenzenden Spalten und einer verschachtelten Tabelle zu lösen.
