將列寬設定為點

Question

我目前有一個tabularx有四列的表格。我這樣初始化環境：

\begin{tabularx}{\linewidth}{l p{0.4\linewidth} | l X l X}

我該如何更改此設置，以便第二列 ( p{0.4\linewidth}) 延伸到頁面中心，但不超過頁面中心？

Answer 1

有兩個連續的表？

\documentclass{article}
    \usepackage{tikz}
%---------------------------------------------------------------%
    \usepackage{booktabs,tabularx,calc}

\usepackage[active,floats,tightpage]{preview}
\setlength\PreviewBorder{1em}

\begin{document}
\begin{table}
    \begin{tabularx}{0.5\linewidth}{lX@{}}  %%% first table
    \hline
        1. column    &   2. column \\
        1. column    &   2. column \\
    \hline
        \end{tabularx}%  
    \begin{tabularx}{0.5\linewidth}{|lXX}               %%% second table
    \hline
        3. column    &   4. column   &   5.column \\
        3. column    &   4. column   &   5.column \\
    \hline
        \end{tabularx}
\end{table}
\end{document}

編輯： 感謝米科，我重新考慮了我的答案。只有當第二列單元格中只有一行時，上述範例才有效。如果這些儲存格中的文字較長，可能的解決方案是將表格放入表格中：

\documentclass{article}
%---------------------------------------------------------------%
    \usepackage{booktabs,tabularx,calc} 
\usepackage[active,floats,tightpage]{preview}
\setlength\PreviewBorder{1em}

\begin{document}
\begin{table}
    \begin{tabularx}{\linewidth}{@{}l|lXX}               
    \hline
{\begin{tabularx}{0.5\linewidth}{lX}  %%% first table in table
1.  &   2. column, but this doesn't work,
                    if the content of this cell is very long,
                    i.e. spread over more line
\end{tabularx}}
    &   3.  &   4. column   &   5. column \\
        \hline
{\begin{tabularx}{0.5\linewidth}{lX}  %%% second table in table
1.  &   2. column, with short text
\end{tabularx}}%
    &   3.  &   4. column   &   this column also can has 
                                longer text span over more lines\\
    \hline
        \end{tabularx}
\end{table}
\end{document}

現在我必須承認，我不再確定，如果你喜歡第二個 cill 總是在頁面中間完成（文字）。
