Losing vertical alignment when using minipage inside tabular

Question

I am using a minipage and an enumerate inside a tabular. However, when I do that, the vertical alignment of the "hello" part in the code is lost.

Here is the code:

\documentclass[12pt]{extarticle}

\usepackage{geometry}
\usepackage{array}
\usepackage{enumitem}


\begin{document}

\begin{tabular}{ >{\centering\arraybackslash} m{2cm} | >{\arraybackslash} m{\textwidth} }
    \textit{Hello} & One \newline
    Two \newline
    \textit{{Three}}
    
\begin{minipage}[t]{\linewidth}
        \begin{itemize}[left=2mm, topsep=0pt, label={-}, noitemsep, nosep, partopsep=0pt, after=\strut]
            \item \small Four
            \item \small Five
        \end{itemize}
    \end{minipage} \\
\end{tabular} 

\end{document}

And here is the output

Does anyone know how to make it vertically aligned? Thank you in advance.

Answer 1

Try:

• remove minipage around list
• by help of etoolbox define list style in preamble
• to list style add minipage, see MWE

\documentclass[12pt]{extarticle}
\usepackage{array}
\usepackage{enumitem}
\usepackage{etoolbox}
\AtBeginEnvironment{tabular}{% <---
    \setlist[itemize]{nosep=0pt,
                     leftmargin=1.5em,
                     label=--,
                     after=\end{minipage},                   
                     before=\begin{minipage}[t]{\linewidth}}
                     }

\begin{document}

\begin{tabular}{ >{\centering\arraybackslash}m{2cm} | m{5cm} }
\textit{Hello}  &   One \newline
                    Two \newline
                    \textit{Three}
                    \begin{itemize}\small 
                \item   Four
                \item   Five
                    \end{itemize}   \\
\end{tabular}

\end{document}

Answer 2

Here is a workaround with {NiceTabular} of nicematrix. In that environment, which is similar to the classical {tabular} (of the package array), there is a command \Block. In your case, you can put Hello in a mono-cell \Block: that allows the use of the key v-center for that \Block. With that key, the content of the block is mathematically centered in the cell (by using PGF computations).

\documentclass[12pt]{extarticle}

\usepackage{geometry}
\usepackage{enumitem}

\usepackage{nicematrix}

\begin{document}

\begin{NiceTabular}{ >{\centering\arraybackslash} m{2cm} | >{\arraybackslash} m{11cm} }[hvlines]
    \Block[v-center]{}{\textit{Hello}} & One \newline
    Two \newline
    \textit{{Three}}

\begin{minipage}[t]{\linewidth}
        \begin{itemize}[left=2mm, topsep=0pt, label={-}, noitemsep, nosep, partopsep=0pt, after=\strut]
            \item \small Four
            \item \small Five
        \end{itemize}
    \end{minipage} \\
\end{NiceTabular} 

\end{document}

You need several compilations, because of the PGF/Tikz nodes used by nicematrix under the hood.
