如何防止表格内的数学运算出现换行？

我有一段 TeX 描述了一个表格

\begin{table}[h]
\begin{tabular}{|p{0.142\linewidth}|p{0.142\linewidth}|p{0.142\linewidth}|p{0.142\linewidth}|p{0.142\linewidth}|p{0.142\linewidth}|p{0.142\linewidth}|}

当我在 Windows 10 上使用 pdflatex 构建它时，我得到了这个输出。

TeX 输出

我想要输出的是这样的：

期望输出

我希望时间 (t) 和 s 位于不同的行，而 \delta t 和 \pm0.11 位于表格第一行的同一行。另外，我希望“未移动”位于同一行。

答案1

我使用\mbox{}以避免换行。此外 - 这与您的问题无关 - 我认为这Time (t) s不是一种“正确”的格式。我会改用Time $t$ in s因为t是一个变量并且应该是斜体（意思是在数学模式下）。“in”也只是一个建议。

\documentclass[]{article}
\usepackage[showframe=true,margin=20mm]{geometry}
\usepackage{float}

\begin{document}

\begin{table}[h]
\begin{tabular}{|p{0.142\textwidth}|p{0.142\textwidth}|}
\hline
% Cell 1
    Angle $\theta$ \newline 
    in deg  \newline 
    \mbox{$\Delta\theta=\pm0.5$} 
& 
% Cell 2 
    Time $t$ \newline 
    in s \newline 
    \mbox{$\Delta t=\pm0.11$}
    \\ \hline
% Data
0.00 & Did not move   
\end{tabular}
\end{table}

即使你制造了细胞太小了（例如 0.042\textwidth）那么仍然没有换行符：

也许看看包 tabularx（错误：缺少数字，视为零。）以及@Werner在他的评论中建议。

答案2

我建议避免重复信息；此外，拼写“没有移动”会使表格过长。

\documentclass{article}
\usepackage{siunitx,booktabs}

\begin{document}
\begin{table}[htp]

\newcommand{\dnm}{{DNM}}

\begin{tabular}{

答案3

由于不知道您的文档的页面布局，以下解决方案基于猜测，这与我们从\usepackage[showframe]{geometry}包中获得的结果接近。

使用包siunitx（用于单位和列格式化）、包tabularx（用于对具有等宽列的表格进行简单格式化）和makecell包标题，我得到了下表：

注意： 的默认字体大小\thead为\footnotesize。

编辑： 将页边距减少到 25mm，\tabcolsep将默认的 6pt 减少到 3pt，并将thead字体大小增加到小\arraystretch到 1.2，表格变为：

笔记2）：当列宽足够大时，方程式就不会被打破，并防止其被打破\mbox{$<equation>$}。此修复可能会导致表格中出现新问题：如果单元格比列宽窄——方程式会溢出到右侧，如图所示Manuel Kuehner 博士答案。我的结论是：修复您的表格的方法是使列的宽度更大......
