Trotz Dutzender Antworten zur vertikalen Zentrierung in Tabellenzellen konnte ich (mein Fehler) keine Lösung für ein anscheinend einfaches Bedürfnis finden, nämlich die vertikale Zentrierung von Zellen in derselben Reihe von handumbrochenen mehrzeiligen Zellen.
\documentclass[12pt]{article}
\usepackage{xcolor}
\usepackage{array}
\begin{document}
\pagecolor{yellow!10}
\newcommand{\methoda}[1]{{\parbox[c]{\linewidth}{\centering#1}}}
\newcommand{\methodb}[3]{\begin{tabular}[c]{@{}c@{}}#1\\#2\\#3\end{tabular}}
\newcommand{\methodc}[1]{\begin{minipage}[m]{\linewidth}\centering#1\end{minipage}}
\newcommand{\methodd}[1]{{\begin{center}#1\end{center}}}
\newcommand{\methoddfix}[1]{{\setlength{\topsep}{0pt}\begin{center}#1\end{center}}}
\centering\begin{tabular}{>{\raggedright\arraybackslash}m{0.28\linewidth}>{\centering\arraybackslash}m{0.33\linewidth}}
\tabularnewline\hline
\centering Column 1 & Column 2\tabularnewline\hline
2 lines vertically centered & This cell contains more than one line of automatically wrapped text. \tabularnewline\hline
Fail of vertical centering & \methoda{Hand-wrapped\\ multiline\\ method A} \tabularnewline\hline
Vert. center. fail & \methodb{Hand-wrapped}{multiline}{method B} \tabularnewline\hline
Fail of vertical centering & \methodc{Hand-wrapped multiline\\ method C\\ too much padding} \tabularnewline\hline
Vert. center. OK & \methodd{Hand-wrapped multiline\\ method D\\ too much padding} \tabularnewline\hline
Success column 1, fail column 2 & \methoddfix{Hand-wrapped multiline\\ method Dfix\\ cannot remove\\ bottom padding} \tabularnewline\hline
Just a last row & Just a last row \tabularnewline\hline
\end{tabular}
\end{document}
Meine reale Tabelle verwendet longtablemöglicherweise multirowein tabularxanderes erweitertes Paket und ist mit XeLaTeX kompiliert.
Vielen Dank im Voraus für jede Hilfe.

Mit makecelloder verschachtelten tabulars und einem pTyp zweite Spalte:
\documentclass[12pt]{article}
\usepackage{array}
\usepackage{makecell}
\begin{document}
With a multicolumn around the automatically wrapped columns:
\centering\begin{tabular}{>{\raggedright\arraybackslash}m{0.28\linewidth}>{\centering\arraybackslash}p{0.33\linewidth}}
\hline
some automatically wrapped text & \makecell[cc]{Some \\ manually \\ linebroken \\ text \\ over multiple lines}\\ \hline
some automatically wrapped text & \begin{tabular}[c]{@{}c@{}}Some \\ manually \\ linebroken \\ text \\ over multiple lines\end{tabular}\\ \hline
some automatically wrapped text & \multicolumn{1}{>{\centering\arraybackslash}m{0.33\linewidth}}{some longer but also automatically wrapped text}\\ \hline
\end{tabular}
With a multicolumn around the manually wrapped columns:
\begin{tabular}{>{\raggedright\arraybackslash}m{0.28\linewidth}>{\centering\arraybackslash}m{0.33\linewidth}}
\hline
some automatically wrapped text & \multicolumn{1}{>{\centering\arraybackslash}p{0.33\linewidth}}{\makecell[cc]{Some \\ manually \\ linebroken \\ text \\ over multiple lines}}\\ \hline
some automatically wrapped text & \multicolumn{1}{>{\centering\arraybackslash}p{0.33\linewidth}}{\begin{tabular}[c]{@{}c@{}}Some \\ manually \\ linebroken \\ text \\ over multiple lines\end{tabular}}\\ \hline
some automatically wrapped text & some longer but also automatically wrapped text\\ \hline
\end{tabular}
\end{document}
Aktualisieren:Um manuelle und automatische Zeilenumbrüche zu kombinieren, können Sie die anfängliche Spaltendefinition so ändern, dass sie „include“ \let\newline\\\arraybackslash\hspace{0pt}statt nur „ist“ \arraybackslash.
