无法在表格中放置加号或减号

Question 1

由于环境的标题行tabular不使用“打字机”（即等宽）字母，因此我不会在正文中使用打字机样式的字母tabular。删除\verb指令并根据需要将数字括在$数学起始符/终止符中似乎是可行的方法。\phantom根据需要使用指令来微调\pm符号前后数字的垂直对齐。

我还将删除\small尤其是\footnotesize指令，因为材料适合文本块。

在下面的例子中，我禁用了所有与当前示例无关的包的加载。

附言：说明

\usepackage[hang, small,labelfont=bf,up,textfont=it,up]{caption}

似乎是矛盾的，因为标题文本部分的字体形状应该都是 up[shape]和it[alics]。无论如何，labelfont 和 textfont 的第二个选项在两种情况下都会被忽略。最好将指令写为

Question 2

为什么 OP 使用\verb|...|？→ 我不知道，也许是为了得到\texttt（打字机字体）？

但是，该\verb命令以逐字模式执行所有内容，因此\pm不会被解释（扩展）而是按字面显示。

为了获得等宽字母，使用\texttt{...}例如。

\documentclass[twoside]{article}

\usepackage{lipsum} % Package to generate dummy text throughout this template


\usepackage[T1]{fontenc} % Use 8-bit encoding that has 256 glyphs
\linespread{1.05} % Line spacing - Palatino needs more space between lines

Question 3

的用法\verb不清楚；据我所知没有正式的表格使用它。

在下面的例子中，我使用了siunitx，此外booktabs；长标题被分成两行，以限制表格宽度。

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

\sisetup{separate-uncertainty}

\begin{document}   

\begin{table}
\centering

\caption{Product Concentrations and Enzyme Reaction Velocities for the 5
  Substrate Concentrations in Varying Inhibitor Environments}

\footnotesize
\newcommand{\head}[1]{{%
  \normalfont\bfseries
  \begin{tabular}{@{}c@{}}
  #1
  \end{tabular}%
}}

\begin{tabular}{
  l
  S[table-format=1.3(4)]
  S[table-format=2.2(4)]
}
\toprule
\head{Metal} & \head{Average Velocity SD} & \head{Average Product \\ Concentration Formed  SD}\\
\midrule
Magnesium & 1.30 \pm 0.67  & 25.97 \pm 13.33 \\
Zinc      & 0.40 \pm 0.049 &  8.06 \pm 0.97 \\
