Antwort1
Eine Lösung ohne Definition neuer Spaltentypen oder Berechnung der Spaltenbreiten. Verwenden Sie einfach die Pakete makecell, captionund multirowplus, hhlineum die Darstellung doppelter Zeilen zu verbessern. Die Tabelle kann auf zwei Arten in Ihre Ränder eingepasst werden: Reduzieren Sie tabcolsepauf 4pt und verwenden Sie entweder eine kleinere Schriftgröße für das Dokument (ich gebe ein Beispiel in 11pt) oder reduzieren Sie die Schriftgröße locallyauf 10pt ( \smallBefehl in 12pt reicht aus).
Übrigens nicht booktabs mit vertikalen Linien verwenden.

Antwort2
Ist es das, wonach Sie gefragt haben? Hier definiert die Lösung ein \mcMakro, das den Text als Argument für die multirowStruktur verwendet, die den Text linksbündig in zwei Zeilen umbricht.
\newcommand\mc[1]{\multicolumn{1}{l||}{\multirow{2}{0.9cm}{#1}}}
