我在 Windows 7 上将软件包与 TeXMaker 一起使用memoir。我想创建一个表 (unsing tabularx)，在其中解释我将在整个文档中使用的符号。符号本身是从 导入的MnSymbol。我不要自始至终使用 MnSymbol 数学字符，但只在序言中导入我需要的几个符号。
现在，由于某种原因，MnSymbol在环境中使用这些字符tabularx会在我的主文档中引入任意垂直空间，如下所示：
为什么？让我困惑的是，当为这个线程编写 MWE 时，错位消失了！这是 MWE 的快照。
table我没有修改主文档中的环境定义memoir。我尝试MnSymbol用“普通”命令替换我创建的宏，但这并不能解决问题。
有人可以帮忙吗？
最小工作示例
\documentclass[a4paper, 11pt, onecolumn, twoside]{memoir}
\usepackage{multirow}
\usepackage{tabularx}
% Import symbols from MnSymbol:
\DeclareFontFamily{U} {MnSymbolC}{}
\DeclareFontShape{U}{MnSymbolC}{m}{n}{

答案1
您的示例没有显示错位，正如此代码所证明的那样，我将其添加\showbase到第一个单元格以标记基线：
\documentclass[a4paper, 11pt, onecolumn, twoside]{memoir}
\usepackage{tabularx}
\usepackage{xcolor}
\newcommand{\showbase}{\makebox[0pt][l]{\vrule height 0pt depth 0.1pt width \textwidth}}
% Import symbols from MnSymbol:
\DeclareFontFamily{U} {MnSymbolC}{}
\DeclareFontShape{U}{MnSymbolC}{m}{n}{
<-6> MnSymbolC5
<6-7> MnSymbolC6
<7-8> MnSymbolC7
<8-9> MnSymbolC8
<9-10> MnSymbolC9
<10-12> MnSymbolC10
<12-> MnSymbolC12}{}
\DeclareFontShape{U}{MnSymbolC}{b}{n}{
<-6> MnSymbolC-Bold5
<6-7> MnSymbolC-Bold6
<7-8> MnSymbolC-Bold7
<8-9> MnSymbolC-Bold8
<9-10> MnSymbolC-Bold9
<10-12> MnSymbolC-Bold10
<12-> MnSymbolC-Bold12}{}
\DeclareSymbolFont{MnSyC} {U} {MnSymbolC}{m}{n}
\DeclareMathSymbol{\medstar}{\mathbin}{MnSyC}{130}
\DeclareMathSymbol{\medlozenge}{\mathbin}{MnSyC}{197}
\DeclareMathSymbol{\medtriangleup}{\mathbin}{MnSyC}{81}
\begin{document}
\begin{table}
\centering
\begin{tabularx}{\textwidth}{>{\showbase}c*4{>{\centering\arraybackslash}X}}
Letter & Caption & Number & Symbol\\
\multicolumn{4}{c}{\rule[-.3\baselineskip]{0pt}{\baselineskip}}\\
A & first line & $1.00$ & $\medstar$ \\
B & second line & $2.00$ & $\medlozenge$ \\
C & third line & $3.00$ & $\medtriangleup$ \\
\multicolumn{4}{c}{\hrulefill}
\end{tabularx}
\caption{Here's a basic table.}
\end{table}
\end{document}
另一方面，如果我将第一个表格行更改为
A & first line & $1.00$ & \color{blue}$\medstar$ \\
我明白了
这确实表明了问题。这恰恰是由\color{blue}启动文本引起的。如果输入是正确的
\textcolor{blue}{$\medstar$}
问题就不会出现。
因此，问题与使用从 导入的符号无关MnSymbol，而只是与 的不当使用有关\color。
请注意，您制定规则或在表格中留出空间的技巧是错误的。
这是一个有效的代码：
\begin{table}
\centering
\begin{tabularx}{\textwidth}{c*4{>{\centering\arraybackslash}X}}
Letter & Caption & Number & Symbol\\[1ex]
A & first line & $1.00$ & \textcolor{blue}{$\medstar$} \\
B & second line & $2.00$ & \textcolor{green}{$\medlozenge$} \\
C & third line & $3.00$ & \textcolor{red}{$\medtriangleup$} \\
\hline
\end{tabularx}
\caption{Here's a basic table.}
\end{table}
我建议booktabs无论如何都要使用。

您的表格“构造”相当不寻常。并且MnSymbol不是问题的根源。
不清楚您想用 实现什么\multicolumn{4}{c}{\rule[-.3\baselineskip]{0pt}{\baselineskip}}\\。相反，我将使用 包中的某些规则booktabs，例如\addlinespace增加行之间的空间、\midrul列标题和其余列之间的行以及bottomrule表格底部的行：
\documentclass[a4paper, 11pt, onecolumn, twoside]{memoir}
\usepackage{multirow}
\usepackage{booktabs} % added 'booktabs', removed 'tabularx' since it is provided by memoir
% Import symbols from MnSymbol:
\DeclareFontFamily{U} {MnSymbolC}{}
\DeclareFontShape{U}{MnSymbolC}{m}{n}{
<-6> MnSymbolC5
<6-7> MnSymbolC6
<7-8> MnSymbolC7
<8-9> MnSymbolC8
<9-10> MnSymbolC9
<10-12> MnSymbolC10
<12-> MnSymbolC12}{}
\DeclareFontShape{U}{MnSymbolC}{b}{n}{
<-6> MnSymbolC-Bold5
<6-7> MnSymbolC-Bold6
<7-8> MnSymbolC-Bold7
<8-9> MnSymbolC-Bold8
<9-10> MnSymbolC-Bold9
<10-12> MnSymbolC-Bold10
<12-> MnSymbolC-Bold12}{}
\DeclareSymbolFont{MnSyC} {U} {MnSymbolC}{m}{n}
\DeclareMathSymbol{\medstar}{\mathbin}{MnSyC}{130}
\DeclareMathSymbol{\medlozenge}{\mathbin}{MnSyC}{197}
\DeclareMathSymbol{\medtriangleup}{\mathbin}{MnSyC}{81}
\begin{document}
\begin{table}
\centering
\begin{tabularx}{\textwidth}{c*4{>{\centering\arraybackslash}X}}
Letter & Caption & Number & Symbol\\
% \addlinespace % it is not clear, if you like to have more vertical space
\midrule % or line as I selected here
A & first line & $1.00$ & $\medstar$ \\
B & second line & $2.00$ & $\medlozenge$ \\
C & third line & $3.00$ & $\medtriangleup$ \\
\bottomrule
\end{tabularx}

有点羞愧的是，添加\renewcommand{\tabularxcolumn}[1]{m{#1}}序言并结合 Zarko 的回答解决了我的问题。希望这也能帮助其他人。
