Bringing vlines in front of hlines

[Aljumaily]

How can I Bringing vertical lines in front of the horizontal lines? The expected result is to have the black vertical lines on top of the red horizontal ones. I would appreciate a solution that could be used in \hline[...] or \cline[...].

\documentclass{article}
\usepackage{xcolor}
\usepackage{tabularray}
\begin{document}

\begin{tblr}{vlines={black, 4pt}} % more important case for me
    \hline[red,4pt]
    Alpha   & Beta  & Gamma  & Delta \\\hline[red,4pt]
    Epsilon & Zeta  & Eta    & Theta \\\hline[red,4pt]
    Iota    & Kappa & Lambda & Mu    \\\hline[red,4pt]
\end{tblr}
\par\vspace{2em}
\begin{tblr}{hlines={red,4pt}, vlines={black, 4pt}}
    Alpha   & Beta  & Gamma  & Delta \\
    Epsilon & Zeta  & Eta    & Theta \\
    Iota    & Kappa & Lambda & Mu    \\
\end{tblr}
\end{document}

After configuring the crossing or trimming positions for both hlines and vlines through keys leftpos and rightpos for hlines and abovepos and belowpos for vlines,

\documentclass{article}
\usepackage{tabularray}
\usepackage{xcolor}

\begin{document}

Hlines ``in front of'' vlines\par
\begin{tblr}{
  hlines={red, 4pt},
  vlines={black, 4pt}
}
    Alpha   & Beta  & Gamma  & Delta \\
    Epsilon & Zeta  & Eta    & Theta \\
    Iota    & Kappa & Lambda & Mu    \\
\end{tblr}
\par\vspace{2em}

Vlines ``in front of'' hlines\par
\begin{tblr}{
  hlines={red, 4pt, leftpos=0, rightpos=0},
  vlines={black, 4pt, abovepos=1, belowpos=1} % seems `belowpos=1` is optional
}
    Alpha   & Beta  & Gamma  & Delta \\
    Epsilon & Zeta  & Eta    & Theta \\
    Iota    & Kappa & Lambda & Mu    \\
\end{tblr}
\end{document}

Thank you @muzimuzhi for the interesting workaround. Suppose that only some of the horizontal/vertical lines need to be shown with horizontal lines displayed using \hline[...] or \cline[...]{...}. How can that be achieved?

\documentclass{article}
\usepackage{xcolor}
\usepackage{tabularray}
\begin{document}

\begin{tblr}{
    vline{1}={1-2}{2pt, azure1},
    vline{2}={1-Y}{2pt, azure3},
    vline{3}={2-4}{2pt, azure5},
    vline{4}={1-5}{2pt, azure7},
    vline{5}={1-Z}{2pt, azure9},
  } % more important case for me
  Alpha   & Beta  & Gamma  & Delta \\\cline[red,2pt]{1-3}
  Epsilon & Zeta  & Eta    & Theta \\
  Epsilon & Zeta  & Eta    & Theta \\\cline[red,2pt]{2-Z}
  Epsilon & Zeta  & Eta    & Theta \\
  Epsilon & Zeta  & Eta    & Theta \\
  Iota    & Kappa & Lambda & Mu    \\\hline[red,2pt]
\end{tblr}

\end{document}

Since leftpos and rightpos are two of keys for hlines, and \hline[<hline keys>] and \cline[<hline keys>]{<column selectors>} both accept <hline keys> as their optional argument, \hline[..., leftpos=n, rightpos=n] and \cline[..., leftpos=n, rightpos=n] are both supported.

\begin{tblr}{
    vline{1}={1-2}{2pt, azure1, abovepos=1, belowpos=1},
    vline{2}={1-Y}{2pt, azure3, abovepos=1, belowpos=1},
    vline{3}={2-4}{2pt, azure5, abovepos=1, belowpos=1},
    vline{4}={1-5}{2pt, azure7, abovepos=1, belowpos=1},
    vline{5}={1-Z}{2pt, azure9, abovepos=1, belowpos=1},
  } % more important case for me
  Alpha   & Beta  & Gamma  & Delta \\ \cline[red,2pt,leftpos=0,rightpos=0]{1-3}
  Epsilon & Zeta  & Eta    & Theta \\
  Epsilon & Zeta  & Eta    & Theta \\ \cline[red,2pt,leftpos=0,rightpos=0]{2-Z}
  Epsilon & Zeta  & Eta    & Theta \\
  Epsilon & Zeta  & Eta    & Theta \\
  Iota    & Kappa & Lambda & Mu    \\ \cline[red,2pt]{1-Z}
                                      \cline[red,2pt,rightpos=0]{Z}
\end{tblr}

Thank you!
