I'm trying to learn tabularray and wanted to setup some custom environments. I really like the idea of being able to move some of the layout markup outside of the actual tabular code, but there are some combinations I can't get to work.

\documentclass{article} \usepackage{xcolor} \usepackage{tabularray} \NewTblrEnviron{my-tabular} \SetTblrInner[my-tabular]{ rows={font=\sffamily}, row{1} = {bg=black!10,font=\sffamily\bfseries}, } \NewColumnType{Z}{X[font=\ttfamily]} \begin{document} \begin{tblr}{ colspec={ZX}, rows={font=\sffamily}, row{1}={bg=black!10,font=\sffamily\bfseries}, } Header left & Header right \\ item 1 left & item 1 right \\ item 2 left & item 2 right \end{tblr} \begin{my-tabular}{ colspec={ZX}, % row{1}={bg=black!10,font=\sffamily\bfseries}, } Header left & Header right \\ item 1 left & item 1 right \\ item 2 left & item 2 right \end{my-tabular} \end{document}

The first table is what I want, but if I try to move the rows and row{1} definitions into a custom environment, the font changing commands from the colspec take priority over the one in row{1}. (Note, repeating the row{1} setting in \begin{my-tabular} works, but it feels very clumsy.)

I'm probably missing something fairly obvious, but I can't figure out a way to have the definitions from \SetTblrInner to override the colspec font changes. Any ideas how to do this in user-friendly way, leaving the code for actual table as clean as possible?

Default inner options set through \SetTblrInner are executed before in-document per-environment inner options, which caused the order-dependent issue OP experienced.

Here's an attempt which adds a similar \SetTblrLateInner command. With it the execution order becomes

- default inner options (\SetTblrInner[tblr]{...}) - in-document inner options (\begin{tblr}{...}) - default late inner options (\SetTblrLateInner[tblr]{...})

Adding support for meta option (an option as a shortcut of a list of other options) would be another solution, and it's more flexible.

\documentclass{article} \usepackage{tabularray} \usepackage{xcolor} \usepackage{xpatch} \ExplSyntaxOn \exp_args:Nc \xapptocmd { NewTblrEnviron ~ code } { \tl_new:c { l__tblr_default_ #1 _inner_late_tl } } { } { \PatchFailed } \xapptocmd \__tblr_parse_table_spec:n { % built-in tblr envs don't have _inner_late_tl \cs_if_exist:cT { l__tblr_default_ \l__tblr_env_name_tl _inner_late_tl } { \keys_set:nv { tblr } { l__tblr_default_ \l__tblr_env_name_tl _inner_late_tl } } } { } { \PatchFailed } \NewDocumentCommand \SetTblrLateInner { O{tblr} m } { \clist_map_inline:nn {#1} { \tl_put_right:cn { l__tblr_default_ ##1 _inner_late_tl } { , #2 } } \ignorespaces } \ExplSyntaxOff \NewTblrEnviron{my-tabular} % use \SetTblrLateInner \SetTblrLateInner[my-tabular]{ rows={font=\sffamily}, row{1} = {bg=black!10,font=\sffamily\bfseries}, } \NewColumnType{Z}{X[font=\ttfamily]} \begin{document} \begin{tblr}{ colspec={ZX}, rows={font=\sffamily}, row{1}={bg=black!10,font=\sffamily\bfseries}, } Header left & Header right \\ item 1 left & item 1 right \\ item 2 left & item 2 right \end{tblr} \begin{my-tabular}{ colspec={ZX}, } Header left & Header right \\ item 1 left & item 1 right \\ item 2 left & item 2 right \end{my-tabular} \end{document}

  • Thank you! That seems to be working well, even in my more complicated real application Commented May 6, 2024 at 8:49
