How to top-align the rotated cell contents of one row in a table?

Question

Consider the following MWE:

\documentclass[]{scrartcl}

% PACKAGES

\usepackage[]{mathtools,amsthm,amssymb,mathrsfs,mathalfa} % Math Packages
\usepackage[]{bm} % To get bold math.
\usepackage[]{makecell} % To get vertical text on cell contents.
\usepackage[]{rotating} % To get vertical text on cell contents.

% SHORT IFF

\renewcommand\iff{\Leftrightarrow}%

% RULE BELOW SECTION TITLES

\begin{document}

\centering
\settowidth\rotheadsize{XXXX}
\renewcommand\theadfont{\normalsize}
\renewcommand{\arraystretch}{2}
\begin{tabular}{cc|cccccccccccc}
    \rothead{$\bm{p}$} & \rothead{$\bm{q}$} & \rothead{$F$} & \rothead{$T$} & \rothead{$p\wedge q$} & \rothead{$p\vee q$} & \rothead{$p\Rightarrow q$} & \rothead{$p\iff q$} & \rothead{$p$} & \rothead{$q$} & \rothead{$\neg p$} & \rothead{$\neg q$}\\[1pt]\hline
    $\bm{T}$ & $\bm{T}$ & $F$ & $T$ & $T$ & $T$ & $T$ & $T$ & $T$ & $T$ & $F$ & $F$\\[1pt]
    $\bm{T}$ & $\bm{F}$ & $F$ & $T$ & $F$ & $T$ & $F$ & $F$ & $T$ & $F$ & $F$ & $T$\\[1pt]
    $\bm{F}$ & $\bm{T}$ & $F$ & $T$ & $F$ & $T$ & $T$ & $F$ & $F$ & $T$ & $T$ & $F$\\[1pt]
    $\bm{F}$ & $\bm{F}$ & $F$ & $T$ & $F$ & $F$ & $T$ & $T$ & $F$ & $F$ & $T$ & $T$\\[1pt]\hline
    \multicolumn{2}{c|}{\rothead{\textbf{Adj.}}} & \rothead{\textit{false}} & \rothead{\textit{true}} & \rothead{\textit{and}} & \rothead{\textit{or}} & \rothead{\textit{impl.}} & \rothead{\textit{equiv.}} & \rothead{\textit{$p$ id.}} & \rothead{\textit{$q$ id.}} & \rothead{\textit{$p$ neg.}} & \rothead{\textit{$q$ neg.}}\\[1pt]
\end{tabular}

\end{document}

The output is as follows:

I want the cell contents of the last row to be horizontally centered (which they already are) but vertically aligned to the top rather than the bottom. I have tried the approach in many answers about vertical alignment of cell contents but without any success.

Can you help me?

Answer 1

Something like this?

\documentclass{scrartcl}

\usepackage{mathtools,amsthm,amssymb,mathrsfs,mathalfa} % Math Packages
\usepackage{bm}       % bold-italic math.
\usepackage{comment}  % easily comment large chunks.
\usepackage{makecell} % get vertical tex.
\usepackage{rotating} % get vertical tex. % twice?

% SHORT IFF
\renewcommand\iff{\Leftrightarrow}%

With {NiceTabular} of nicematrix.

\documentclass{scrartcl}
\usepackage{nicematrix}

\begin{document}

\begin{table}
\centering
\renewcommand{\arraystretch}{2}
\begin{NiceTabular}
  [
    first-row , code-for-first-row = \rotate ,
    last-row = 5 , code-for-last-row = \rotate , % \rotate in last-row will do the top-alignment
  ]
  {*{2}{>{\mathversion{bold}}c}!{\vrule}cccccccccc}
    $p$ & $q$ & $F$ & $T$ & $p\wedge q$ & $p\vee q$ & $p\Rightarrow q$ & $p \iff q$ & $p$ & $q$ & $\neg    p$ & $\neg q$ \\ \hline
