What about a `lines` option that would set both `hlines` and `vlines`?

What about a lines option that would set both hlines and vlines?

This would be useful to avoid repetition, for example in the following case:

\begin{tblr}{
  hlines = {red,1mm,dotted},
  vlines = {red,1mm,dotted},
  }
...
\end{tblr}

You can also use \DeclareTblrKeys for this:

\documentclass{article}
\usepackage{tabularray}
\usepackage{ninecolors}
\DeclareTblrKeys{table/inner}{
  hvlines .meta:n = {
    hlines = {#1},
    vlines = {#1}
  }
}
\begin{document}

\begin{tblr}{
  hvlines = {red, dashed}
}
  Head    & Head  & Head   & Head \\
  Alpha   & Beta  & Gamma  & Delta \\
  Epsilon & Zeta  & Eta    & Theta \\
  Iota    & Kappa & Lambda & Mu    \\
  Alpha   & Beta  & Gamma  & Delta \\
  Epsilon & Zeta  & Eta    & Theta \\
  Iota    & Kappa & Lambda & Mu
\end{tblr}

\end{document}

Nice! But what about providing it by the package?

[lvjr]

Sorry, I will keep tabularray minimal and extendable.

[dbitouze]

I can understand but this would be just a tiny enhancement.

BTW, I would prefer the name hvlines.

Too bad this is closed as not planned!
