在 tabular* 环境中根据内容调整单元格宽度

Question

我有一个两列的表格*环境，我希望自动调整每行第一个单元格的宽度以适应其内容。如何删除附图中的水平空格“x”？

MWE如下：

\documentclass{article} % 
\usepackage{tabularx}
\usepackage{blindtext}
\setlength\tabcolsep{1pt}
\newenvironment{twenty}{%
    \begin{tabular*}
    {\textwidth}{ll}}{%
    \end{tabular*}}
\newcommand{\twentyitem}[4]{%
{#1}&\parbox[t]{0.75\textwidth}{%
        \textbf{#2}%
        \hfill%
        {#3}\\%
        #4\vspace{\parsep}}\\}

\begin{document}
\begin{twenty}
    \twentyitem{2017 Sept~-~%\dots
    a very long date here}{ABC Position}{City, Country}%
    {\blindtext}    
    \twentyitem{2015 May~-~%\dots
    2017 Sept}{XYZ Position}{City, Country}%
    {\blindtext}    
\end{twenty}    
\end{document}

Answer 1

tabularx以下是对每个条目使用新环境的解决方案：

\documentclass{article}
\usepackage{tabularx}
\usepackage{blindtext}

\newcommand{\myentry}[4]{\begin{tabularx}{\textwidth}{lX}#1 & \textbf{#2} \hfill #3 \newline #4 \\ \end{tabularx}}

\begin{document}
\noindent
\myentry{2017 Sept - a very long date here}{ABC position}{City, Country}{\blindtext}
\myentry{2015 May~-~2017 Sept}{XYZ Position}{City, Country}{\blindtext}
\end{document}

Answer 2

我将使用它right alignment作为第一列。

\documentclass{article} %
\usepackage{tabularx}
\usepackage{blindtext}
\setlength\tabcolsep{1pt}
\newenvironment{twenty}{%
    \begin{tabular*}
    {\textwidth}{rl}}{%
    \end{tabular*}}
\newcommand{\twentyitem}[4]{%
{#1}&\parbox[t]{0.75\textwidth}{%
        \textbf{#2}%
        \hfill%
        {#3}\\%
        #4\vspace{\parsep}}\\}

\begin{document}
\begin{twenty}
    \twentyitem{2017 Sept~-~%\dots
    a very long date here}{ABC Position}{City, Country}%
    {\blindtext}
    \twentyitem{2015 May~-~%\dots
    2017 Sept}{XYZ Position}{City, Country}%
    {\blindtext}
\end{twenty}
\end{document}
