这个问题是上一个问题的延续longtabu 的相同实例
我想创建一个环境，在这个环境中，longtabu为第二个环境实例确定的列宽将在整个文档中使用。David Carlisle 在上一篇文章中给出了一个很好的解决方案 -
\documentclass{article}
\usepackage{longtable,tabu}
\newenvironment{listazo}{
\begin{longtabu} to \textwidth{X[-1l]X}}
{\end{longtabu}}
\makeatletter
\AtBeginDocument{%
{\let\ifhmode\iftrue
\xdef\tmp{\csname LT@ii\endcsname}%
\xdef\tmp{\expandafter\@gobble\tmp}}%
}
\makeatother
\begin{document}
\section*{First}
\begin{listazo}
side note1 & here is the text and details\\\tmp\kill
\end{listazo}
\section*{Second}
\begin{listazo}
side note 2 & more text and details over here - bbbbbbbb bbbbb bbbb bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb\\
longer side note & bbbb bbb bbb bbb bb bb bb bb b b b b b b bbbb bbb bbb bbb bb bb bb bb b b b b b b
\end{listazo}
\end{document}
结果正如我所愿。但是，如果我将对齐设置更改为longtabu右对齐，如下所示 -
\newenvironment{listazo}{
\begin{longtabu} to \textwidth{X[-1r]X}} % changed 'l' for 'r' here
{\end{longtabu}}
第一个表格的第一列仍然像这样左对齐（注意：添加 \hfill 并没有解决这个问题）
非常感谢您的帮助 - 我对此束手无策。
干杯

哦，这次稍微脆弱一些，但是
\documentclass{article}
\usepackage{longtable,tabu}
\newenvironment{listazo}{
\begin{longtabu} to \textwidth{X[-1r]X}}
{\end{longtabu}}
\makeatletter
\AtBeginDocument{%
{\let\ifhmode\iftrue\def\omit{\noindent}%
\xdef\tmp{\csname LT@ii\endcsname}%
\xdef\tmp{\expandafter\@gobble\tmp}}%
}
\makeatother
\begin{document}
\section*{First}
\begin{listazo}
side note1 & here is the text and details\\\tmp\kill
\end{listazo}
\section*{Second}
\begin{listazo}
side note 2 & more text and details over here - bbbbbbbb bbbbb bbbb bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb\\
longer side note & bbbb bbb bbb bbb bb bb bb bb b b b b b b bbbb bbb bbb bbb bb bb bb bb b b b b b b
\end{listazo}
\section*{test}
\begin{listazo}
side note1 & here is the text and details\\
side note 2 & more text and details over here - bbbbbbbb bbbbb bbbb bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb\\
longer side note & bbbb bbb bbb bbb bb bb bb bb b b b b b b bbbb bbb bbb bbb bb bb bb bb b b b b b b
\end{listazo}
\end{document}
