csvsimple和新包之间是否存在不兼容性tabularray？以下 MWE 会引发错误。（使用 XeLaTeX 或 LuaLaTeX 进行编译）
\documentclass{article}
\usepackage[ngerman,french]{babel}
\usepackage{fontspec}
\usepackage{tabularray} %needs package ninecolors.sty
\usepackage{booktabs}
\usepackage{csvsimple}
\begin{filecontents*}{data.csv}
frA,frB,deA
un cogne,arg.,ein Bulle
morfler,arg.,eins abkriegen
\end{filecontents*}
\begin{document}
This is what I'd like to obtain, with environment \verb|tblr|:
\noindent
\begin{tblr}{colspec={X[2,l]X[4,l]},
width=0.5\linewidth,
hlines,
}
\textit{un cogne} (arg.)& \textit{un policier ou un gendarme}\\
\textit{morfler} (arg.)& {\selectlanguage{ngerman}\textit{eins abkriegen}}\\
\end{tblr}
\bigskip
A normal tabular seems to work (but I'd miss the fonctions of tabularray...)
(not only the X column type, also the alignment facilities):
% \csvreader
\noindent
\begin{tabular}{p{4cm}p{8cm}}\toprule
\csvreader[
late after line=\\\midrule,
late after last line=\\\bottomrule,
head to column names,
]{data.csv}{}{%
\textit{\frA} (\frB) & \textit{\deA}
}
\end{tabular}
\bigskip
But this throws an error:
\noindent
\begin{tblr}{
colspec={X[2,l]X[4,l]},
width=0.5\linewidth,
hlines,
}
\csvreader[
late after line=\\\midrule,
late after last line=\\\bottomrule,
head to column names,
]{data.csv}{}{%
\textit{\frA} (\frB) & \textit{\deA}
}
\end{tblr}
\end{document}
答案1
更新：
与csvsimplev2.1.0 (2021/07/06)csvsimple-l3兼容tabularray。
您应该使用\usepackage[l3]{csvsimple}或\usepackage{csvsimple-l3}来加载csvsimple-l3，而不是被取代的csvsimple-legacy。
\begin{filecontents*}{data.csv}
frA,frB,deA
un cogne,arg.,ein Bulle
morfler,arg.,eins abkriegen
\end{filecontents*}
\documentclass{article}
\usepackage[ngerman,french]{babel}
\usepackage{fontspec}
\usepackage{tabularray} %needs package ninecolors.sty
\usepackage{booktabs}
\usepackage[l3]{csvsimple} % or "\usepackage{csvsimple-l3}"

输出与下面相同。
原来的：
这是第一次尝试csvsimple。想法是\csvloop（按照 的口味csvsimple-legacy）首先将整个表格谱表存储在宏中（此处\csv@output），而不是直接打印它们。然后用户可以用来\csvoutput打印表格。
受限于tabularray实现方式，每个\hline类似谱表、、\\和&都应该在中直接看到\csv@output。
