刪除表格環境中「itemize」清單上方的空間

Question

我想以緊湊的方式itemize在 -environment 中包含一個 -list以節省空間。table然而，當在表格中時，列表上方有一個很大的間隙，但在普通文本中的段落之後則沒有：

\documentclass[12pt]{scrbook}
%\usepackage[autooneside=false, headsepline, plainheadsepline, automark]{scrlayer-scrpage}
\linespread{1}
\usepackage{paralist}
\usepackage{enumitem} % enumerate?
\usepackage{tabularx}

\begin{document}
some text
\begin{compactitem}  \item  point1  \item point2 \end{compactitem}
\begin{table}[ht!]
    \setlength{\leftmargini}{7pt}
    \begin{tabularx}{\linewidth}{l | X | X }\hline \hline
        & ECB& FED\\ \hline
    M1 & \begin{itemize}[noitemsep,topsep=0pt]   \item  point1  \item point2 \end{itemize} 
      & \begin{compactitem}  \item  point1  \item point2   \end{compactitem}
    \end{tabularx}
\end{table}

\end{document}

正如您所看到的，我測試了compactitemfromparalist包以及itemizefromenumitem及其 options [noitemsep,topsep=0pt]。它們產生的高度略有不同。這在普通段落之間有效，但在表格中則不然。我希望“point1”與“M1”處於同一水平。

這個有一個輕微的縮進，當有換行時可以看到（單字“Assets”比單字“during”更靠右），是以下結果：

\begin{minipage}[t]{\hsize}\begin{compactitem}
 \item Assets can be \textbf{difficult to value} during periods of hyperinflation
\end{compactitem}\end{minipage}

比較兩個建議的解決方案：下面的MWE直接比較了兩種解決方案，定義了新的環境，分別命名為compactitemt和compactitemm。

\documentclass%[12pt,abstracton,titlepage,parskip=false, no, no,twoside=true,open=right]
{scrbook}
%\usepackage[autooneside=false, headsepline, plainheadsepline, automark]{scrlayer-scrpage}

%\usepackage{listings}
\usepackage{paralist}
%\usepackage{newtxtext}%antpolt mathpazo %\usepackage{mathptmx} %\usepackage{newtxtext} 
\usepackage{enumitem} % enumerate?
\newenvironment{compactitemm}{\begin{minipage}[t]{\hsize}\begin{compactitem}}{\end{compactitem}\end{minipage}} %this solution requires enumitem package
\newenvironment{compactitemt}{\begin{itemize}[nosep, wide=0pt,
  %left=0pt %for neat, wide=0pt %for flush left to save space
  before={\begin{minipage}[t]{\hsize}},
  after ={\end{minipage}} ]   }{ \end{itemize} }
\renewcommand{\familydefault}{\sfdefault}

\usepackage{tabularx}

\begin{document}

\begin{table}
\setlength{\leftmargini}{7pt} %this impacts the left margin of itemize package, i.e. ``stuff 2'' in table. 7pt aligns with the other solution. 
\begin{tabularx}{\linewidth}{X | X }\hline
\multicolumn{2}{c}{stuff 1}\\ \hline
\begin{compactitemt}
  \item x This line should break and we see where the next begins
  \item y
  \item z
\end{compactitemt}
& \begin{compactitemt}
  \item a This line should break and we see where the next begins
  \item b
\end{compactitemt}\\ \hline 
\multicolumn{2}{c}{stuff 2}\\ \hline
\begin{compactitemm}
  \item x This line should break and we see where the next begins
  \item y
  \item z This line should break and we see where the next begins
\end{compactitemm}
& \begin{compactitemm}
  \item a This line should break and we see where the next begins
  \item b
\end{compactitemm}\\ \hline 
\end{tabularx}
\caption{MWE}
\end{table}

\end{document}

Answer 1

• 如果您使用compactitem環境，則需要將其包含在\begin{minipage}[t]{\hsize}和\end{minipage}語句中。

• 如果您將itemize環境與enumitem套件一起使用，則可以新增語句

  before={\begin{minipage}[t]{\hsize}},
  after ={\end{minipage}}
  

  到與 一起的選項清單\begin{itemize}。

\documentclass[12pt]{scrbook}
\usepackage{paralist,enumitem,tabularx}
\begin{document}

\begin{table}[ht!]
    \setlength\extrarowheight{2pt} % optional, for a slighly more open "look"
    \setlength{\leftmargini}{7pt}
    \begin{tabularx}{\linewidth}{l | X | X }
    \hline \hline
       & ECB & FED\\ 
    \hline
    M1 & \begin{itemize}[nosep, left=0pt,
                         before={\begin{minipage}[t]{\hsize}},
                         after ={\end{minipage}} ]   
         \item point1  
         \item point2 
         \end{itemize} 
       & \begin{minipage}[t]{\hsize}
         \begin{compactitem}  
         \item point1  
         \item point2   
         \end{compactitem}
         \end{minipage}\\
    \hline
    \end{tabularx}
\end{table}

\end{document}

Answer 2

對於上面的空間，足以讓 LaTeX 認為該單元格是一個小型頁面。為此，我借用了\compress在該網站上的一個問題的答案中找到的命令。對於下面的空間，您必須在末尾添加一個負的 \baselineskip 。

\documentclass[12pt]{scrbook}
%\usepackage[autooneside=false, headsepline, plainheadsepline, automark]{scrlayer-scrpage}
\linespread{1}
\usepackage{paralist}
\usepackage{enumitem} % enumerate?
\usepackage{tabularx}
\makeatletter
\newcommand{\compress}{\@minipagetrue}
\makeatother

\begin{document}
some text
\begin{compactitem} \item point1 \item point2 \end{compactitem}
\begin{table}[ht!]
    \setlength{\leftmargini}{7pt}
    \begin{tabularx}{\linewidth}{l | >{\compress}X |>{\compress} X }\hline \hline
        & ECB& FED\\ \hline
    M1 & \begin{itemize}[nosep, after=\vspace{-\baselineskip}] \item point1 \item point2 \end{itemize}\\
\hline
    & & \begin{compactitem} \item point1 \item point2 \end{compactitem}\leavevmode\vspace*{-\baselineskip}
       \\
\hline
    \end{tabularx}
\end{table}

\end{document}
