将 p{width} 生成的 parbox 移动到表格的最右侧

Question

我们重点关注以下代码：

\documentclass{book}
\begin{document} 
\begin{tabular}
{|l|
r@{}@{\hspace{0.3em}}
|l|r|}
%--------------------------------------------------------------------
\textbf{(2)}
&$x$
&$=a+b+c+d+e$
&Putting some reasons here\\ 
\hline
%--------------------------------------------------------------------
\textbf{(4)}
&\multicolumn{2}{p{5cm}}{Some multi lines sentences here.
            Some multi lines sentences here.}\vline
& \multicolumn{1}{p{2.5cm}}{I love to move this parbox to very right of the table, that will 
be great}\vline\\
\end{tabular}
\end{document}

它创建如下表：

我喜欢将 parbox 移到最右边以移除黄色空间，你知道怎么做吗？

Answer 1

我和 Zarko 理解的事情不一样（而且我的理解速度慢得多）。

    \documentclass{book}
    \usepackage{tabularray}
    %%%%%%%%%%%%%%%%%%%%%
    \begin{document} 

    \begin{tblr}
        {
        hlines,vlines,
        colspec = {
                    Q[c,m,wd=1.5em,font=\bfseries]
                    Q[l]
                    Q[l]
                    Q[r]},
        cell{2}{2}={c=2}{l}
        }
        %\mycnt
        (2)
        &$x$
        &$=a+b+c+d+e$
        &Putting some reasons here\\
        (4)
        &{Some multi lines sentences here.\\
        Some multi lines sentences here.}
        && \parbox[t]{2.5cm}{I love to move this parbox to very right of the table, that will 
        be great}
    \end{tblr}
    \end{document}

Answer 2

目前尚不清楚，表格最后一列的宽度是多少：

• 2.5 厘米，可以从\multicolumn{1}{p{2.5cm}}{...} 您的 MWE 中得出，或者
• 最后两列可以有相等的宽度

因此，下面是两种情况的示例，使用了tabular˛,tabularx andtblr (defined intabularray` 包）表：

\documentclass{book}
%\usepackage{microtype}
\usepackage{tabularray,
            tabularx}
\begin{document}
    \begin{table}[ht]
\caption{The case when width of the last column is 2,5 cm}
    \centering
\begin{tabular}{|l| p{5cm} | p{2.5cm}|}
\textbf{(2)}    & $x=a+b+c+d+e$ & Putting some reasons here \\
    \hline
\textbf{(4)}    & Some multi lines sentences here.
            Some multi lines sentences here.
                & I love to move this parbox to very right of the table, that will be great
\end{tabular}

\medskip
\begin{tblr}{colspec={Q[l, font=\bfseries] Q[l, 5cm] Q[l, 2.5cm]},
             vlines}
(2) & $x=a+b+c+d+e$ & Putting some reasons here \\
    \hline
(4) & Some multi lines sentences here.
      Some multi lines sentences here.
                    & I love to move this parbox to very right of the table, that will be great
\end{tblr}
    \end{table}

    \begin{table}[ht]
\caption{The case when the last two columns have equal width}
\begin{tabularx}{\linewidth}{|l| X | X |}
\textbf{(2)}    & $x=a+b+c+d+e$ & Putting some reasons here \\
    \hline
\textbf{(4)}    & Some multi lines sentences here.
            Some multi lines sentences here.
                & I love to move this parbox to very right of the table, that will be great
\end{tabularx}

\medskip
\begin{tblr}{colspec={Q[l, font=\bfseries] X[l] X[l]},
             vlines}
(2) & $x=a+b+c+d+e$ & Putting some reasons here \\
    \hline
(4) & Some multi lines sentences here.
      Some multi lines sentences here.
                    & I love to move this parbox to very right of the table, that will be great
\end{tblr}
    \end{table}
\end{document}

Answer 3

不需要\multicolumn。拆分单个单元格然后合并所有其他列更容易；解决方案使用内部。然后，定义自动添加换行符的段落array列也更容易p{}

\documentclass{book}
\begin{document}
\bgroup
\centering
\begin{tabular}{| l | p{5cm} | p{4cm} |}
  \textbf{(2)}
    & \(\begin{array}{@{}r|l@{}}x & = a + b + c + d + e\end{array}\)
    & Putting some reasons here \\
  \hline
  \textbf{(4)}
    & Some multi lines sentences here. Some multi lines sentences here.
    & I love to move this parbox to very right of the table, that will be great} \\
\end{tabular}
\par
\egroup
\end{document}
