Apesar de dezenas de respostas sobre centralização vertical em células de tabela, não consegui (culpa minha) encontrar uma solução para uma necessidade aparentemente simples, centralização vertical de células na mesma linha de células multilinhas enroladas à mão.
\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}
Minha tabela do mundo real é um longtableuso de multirowe talvez tabularxalgum outro pacote avançado adicional e é compilada com XeLaTeX.
Agradecemos antecipadamente por qualquer ajuda.

Com makecellou aninhados tabulare um ptipo de segunda coluna:
\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}
Atualizar:Para combinar quebras de linha manuais e automáticas, você pode alterar a definição inicial da coluna para incluir \let\newline\\\arraybackslash\hspace{0pt}em vez de apenas \arraybackslash.
