Context

I have a dark coloured table header and white vertical lines in that header. I want to set these options as a default for the tblr environment. From the manual, page 32 I read that I can do so using the \SetTblrInner command. But when I do so, the vertical lines defined in the colspec don't align with the vertical lines coloured by vline.

MWE

This is my starting point:

\documentclass{article} \usepackage{xcolor} \usepackage{tabularray} \begin{document} \begin{table}[htp] \begin{tblr}{ colspec = {|l|l|l|}, row{1} = {bg=blue, fg=white, font=\bfseries}, hline{1,2,Z} = {}, vline{2-Y} = {1}{white}, } A & B & C\\ 1 & 2 & 3\\ 10 & 20 & 30\\ 100 & 200 & 300\\ \end{tblr} \end{table} \end{document}

enter image description here

Now I move all options except the colspec (as that changes from table to table) into the \SetTblrInner command:

\documentclass{article} \usepackage{xcolor} \usepackage{tabularray} \SetTblrInner{ row{1} = {bg=blue, fg=white, font=\bfseries}, hline{1,2,Z} = {}, vline{2-Y} = {1}{white} } \begin{document} \begin{table}[htp] \begin{tblr}{ colspec = {|l|l|l|} } A & B & C\\ 1 & 2 & 3\\ 10 & 20 & 30\\ 100 & 200 & 300\\ \end{tblr} \end{table} \end{document}

And I get this:

Changing the vline color and zooming in, it's visible that the thick white part is not actually the line, but a blank space between the vline line and the | line:

Question

How can I set default tblr options while also using colspec in the individual tables?

What I've tried

I have removed the intra-column pipe | from the colspec

colspec = {|lll|}

and set the vertical lines completely in the \SetTblrInner part

\SetTblrInner{ ... vline{2-Y} = {2-Z}{black} }

That removes the issue, but reduces flexibility.

If you leave also the | in the colspec you're drawing two vertical lines.
Leave them out and arrange the vline options.

\documentclass{article} \usepackage{xcolor} \usepackage{tabularray} \SetTblrInner{ row{1} = {bg=blue, fg=white, font=\bfseries}, hline{1,2,Z} = {}, vline{1,Z} = {}, vline{2-Y} = {1}{white}, vline{2-Y} = {2-Z}{}, } \begin{document} \begin{table}[htp] \begin{tblr}{ colspec = {lll} } A & B & C\\ 1 & 2 & 3\\ 10 & 20 & 30\\ 100 & 200 & 300\\ \end{tblr} \end{table} \end{document}

This in not a workaround, it's a feature of the package.
It allows you to draw how many rules do you like, see this example:

\documentclass{article} \usepackage{xcolor} \usepackage{tabularray} \begin{document} \begin{table}[htp] \begin{tblr}{ colspec = {l|||l|||l} } A & B & C\\ 1 & 2 & 3\\ 10 & 20 & 30\\ 100 & 200 & 300\\ \end{tblr} \end{table} \end{document}

Also an ordinary tabular would behave this way.

  • Thanks, I edited this workaround briefly after asking the question. I guess my issue is: why are the | lines not the same lines as the ones drawn by vline? Commented Dec 17, 2023 at 11:52
  • @SaaruLindestøkke It's a feature of the package, you can draw more then one line, see page 16 of the documentation, for example. Commented Dec 17, 2023 at 11:57
  • @SaaruLindestøkke See my renewed answer, hope it explains the reason of this behavior. Commented Dec 17, 2023 at 12:02
  • Ok, so the | symbol is simply not equal to a vline, right? These are just different things and I should not expect them to be usable interchangeably? Commented Dec 17, 2023 at 12:48
  • @SaaruLindestøkke They are the same. You can have more vline, too, with the same behavior. Commented Dec 17, 2023 at 13:30
