Vertical alignment in longtable cells

Question

I read hundreds of threads now, but I don't get the point. Why isn't the text in the left column of the following table vertically centered?

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{booktabs}
\usepackage{multirow}
\usepackage{pdflscape}
\usepackage{longtable, array}
\usepackage{lipsum}
\begin{document}
\begin{landscape}
  \begin{longtable}{ m{0.1\linewidth} p{.35\linewidth}p{.55\linewidth} }
  \endfirsthead
  \endhead
  \toprule
  \textbf{Enum} & \textbf{Example} & \textbf{Description} \
  \midrule
  1 & test & \lipsum[50]\
  \midrule
  2a & test & \lipsum[50]\
  2b & test & \lipsum[50]\
  \bottomrule
  \end{longtable}
\end{landscape}
\end{document}

My local compiler as well as overleaf produce the following output

Can anybody help? If possible I would also like to have the text in the left column centered horizontally, but I think this will be done quickly then.

you must center the last column relative to the baseline:, \begin{longtable}{p{0.1\linewidth} p{.35\linewidth}m{.55\linewidth} } — Ulrike Fischer, Dec 30 '21 at 20:56
That totally did the trick, thanks. But can you explain why Latex behaves like this? It sounds counterintuitive to me. — Martin Herrmann, Dec 30 '21 at 21:05

With tabularray is simple:

\documentclass{article}
\usepackage{pdflscape}
\usepackage{tabularray}
\UseTblrLibrary{booktabs}
\usepackage{lipsum}
\begin{document}
\begin{landscape}
  \begin{longtblr}[
caption = {caption text},
  label = {tab:longtblr}
                    ]{
  colspec = {Q[c] X[l] X[1.6,m,j]},
   row{1} = {font=\bfseries},
  rowhead = 1
                     }
  \toprule
Enum    &   Example &   Description \
  \midrule
  1     &   test    &   \lipsum[50] \
  \midrule
  2a    & test      &   \lipsum[50] \
  \addlinespace
  2b    & test      &   \lipsum[50] \
  \bottomrule
  \end{longtblr}
\end{landscape}
\end{document}

Where meaning of the used column specifications are:

Q[c] (or shorter c) define columns with horizontal centered contents
X[l] define X column (similar as at tabularx package) where option l define that column contents is left aligned
X[1.6,m,j is define X similar as above, however options 1.6 make it wide for 1.6 time, m vertical center cells contents, and j that cells content is justified.

thanks a lot, that works, however, I am restricted to longtable. — Martin Herrmann, Jan 03 '22 at 11:51
