如何为 csvreader 读取的长 tabularray 表添加标题？

2024-5-26 • tag-icon

我正在使用 csvsimple 包从不同的 CSV 文件中读取补充信息的数据。为了更好地显示内容，我编写了自己的 csvstyle，因为所有 CSV 文件的格式都相同。对于某些表格，数据太长，需要多页。只需将 csvstyle 更改为使用long tabularray而不是，即可轻松实现tabularray。现在出现问题，当我想为这个长表添加标题时：如果我将和换行，\csvreader例如\caption，\begin{table}表格将不再进行分页；如果我使用例如\begin{longtable}而不是\begin{table}，编译将不再起作用，每一行都会有另一个标题行，诸如此类，具体取决于包装器。

在此处添加标题的正确步骤是什么？

下面是一个带有 \begin{table} 的最小可重现示例，不进行分页。

\documentclass{article}
\pagestyle{empty}

\usepackage[T1]{fontenc}
\usepackage[english]{babel}
\usepackage{blindtext}
\usepackage[table,xcdraw,dvipsnames]{xcolor}
\usepackage[labelfont={bf}, font=small, justification=justified]{caption}
\usepackage[version=4]{mhchem}
\usepackage{chemformula}
\usepackage[separate-uncertainty = true, multi-part-units=single]{siunitx} 
\usepackage{sectsty}
\usepackage{tabularx}
\usepackage{listings}
\usepackage{longtable}
\usepackage{array}
\usepackage{hhline}
\usepackage{booktabs}

% For including csv as tables
\usepackage{tabularray} 
\UseTblrLibrary{siunitx}
\usepackage{csvsimple-l3}

\NewTableCommand\toprule{\hline[0.08em]}
\NewTableCommand\midrule{\hline[0.05em]\vspace{1pt}}
\NewTableCommand\bottomrule{\hline[0.08em]}

\csvstyle{MyStyleLong}{

环境longtblr提供了密钥caption作为选项。据我所知，csvsimple不提供对这些选项的任何访问。但是，可以按以下方式重新定义模板的默认文本：

\begin{document}

\blindtext

% the first empty is for using S as first column
\DefTblrTemplate{caption-text}{default}{Test}
\csvreader[MyStyleLong, filter expr={test{\ifnumgreater{\thecsvinputline}{1}}}]{test-file-long.csv}{}{\empty & \csvcoli & \csvcolii & \csvcoliii }

\end{document}
