表格格式错误额外的对齐标签 
\begin{table}{ht}
\begin{tabular}{|cc|}
\hline
10g & Tryptone //
5g  & Yeast extract //
5g  & NaCl //
10g & Agar //
1ml & Ampicllin (100ng/ml)  /hline
\end{tabular}
\caption{Reagents for Lysogeny broth agar}
\label{table:LBAreagents}

\end{table}

我不断收到错误消息，我无论如何也找不到问题所在，据说错误发生在酵母和琼脂代码行中，代码如下

Extra alignment tab has been changed to \cr.
<recently read> \endtemplate
l.164 5g &
Yeast //
You have given more \span or & marks than there were
in the preamble to the \halign or \valign now in progress.
So I'll assume that you meant to type \cr instead.

任何帮助都将非常感激。

答案1

像这样？

我把 改为{ht}，[ht]然后 替换为//，并 在最后一个之前\\添加了一个额外的\\\hline

\begin{table}[ht]
\begin{tabular}{|cc|}
\hline
10g & Tryptone \\
5g  & Yeast extract \\
5g  & NaCl \\
10g & Agar \\
1ml & Ampicllin (100ng/ml) \\
\hline
\end{tabular}
\caption{Reagents for Lysogeny broth agar}
\label{table:LBAreagents}

\end{table}

我还擅自更新了表格，并向您介绍了siunitx显示 SI 单位数字的包、mhchem化学式包和booktabs用于更美观的表格格式的包。但这当然是我的偏好 :)

\documentclass[12pt,a4paper]{report}
\usepackage[utf8]{inputenc}
\usepackage{mathptmx}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage[left=2cm,right=2cm,top=2cm,bottom=2cm]{geometry}
\usepackage{color}
\usepackage{multirow}
\usepackage{soul}
\usepackage{caption}
\usepackage{natbib}
\usepackage{setspace}
\usepackage{placeins}
\usepackage[nottoc,numbib]{tocbibind}
\renewcommand{\bibname}{References}
\doublespacing
\usepackage[parfill]{parskip}
\usepackage{booktabs}
\usepackage{siunitx}
\usepackage[version=3]{mhchem}
\begin{document}
\begin{table}[ht]
\centering
\caption{Reagents for Lysogeny broth agar}
\label{table:LBAreagents}
\begin{tabular}{cc}
\toprule
Quantities & Ingredient \\
\midrule
\SI{10}{\gram} & Tryptone \\
\SI{5}{\gram}  & Yeast extract \\
\SI{5}{\gram}  & \ce{NaCl} \\
\SI{10}{\gram} & Agar \\
\SI{1}{\milli\litre} & Ampicllin (\SI{100}{\nano\gram\per\milli\litre)} \\
\bottomrule
\end{tabular}

\end{table}

\end{document}

会给出类似这样的结果

以下是我使用功能强大的siunitx包裹：

\documentclass{report}

\usepackage[tableposition = top]{caption} % table caption position
\usepackage{booktabs}                     % horizontal lines in table
\usepackage{siunitx}                      % typesetting and aligning physical quantities 
\usepackage[version = 4]{mhchem}          % format names of chemical components

\begin{document}

\begin{table}
\centering
 \caption{Reagents for Lysogeny broth agar.}
 \label{table:LBAreagents}
  \begin{tabular}{
    S[table-format = 2] @{\,}
    s[table-unit-alignment = left]
    l
  }
   \toprule
    10 & \g  & Tryptone      \\
     5 & \g  & Yeast extract \\
     5 & \g  & \ce{NaCl}     \\
    10 & \g  & Agar          \\
     1 & \ml & Ampicllin (\SI[per-mode = symbol]{100}{\ng\per\ml}) \\
   \bottomrule
  \end{tabular}
\end{table}

\end{document}

输出

注意前两列的物理量和单位是垂直对齐的。这是“正确”的做法。
