表格的 Latex 代码不起作用

Question

我正在尝试这张表 -

这是我的乳胶代码 -

\section{Introduction}

\begin{table}[]
\begin{tabular}{|c|l|}
\hline
\begin{tabular}[c]{@{}c@{}}Overall order \\ of reaction\end{tabular} &
  \multicolumn{1}{c|}{\begin{tabular}[c]{@{}c@{}}Units of rate constant (Remember \\ that time can be given in any units)\end{tabular}} \\ \hline
0 & \begin{tabular}[c]{@{}l@{}}\[\\ \frac{mol}{dm^{3} \times time} =mol\ dm^{-3} \ time^{-1}\\ \]\end{tabular}          \\ \hline

n &
  \begin{tabular}[c]{@{}l@{}}\[\\ (\text{concentration})^{1-n} \times time^{-1}\]\\ can also be written as - \\ \[\left(\frac{mol}{dm^{3}}\right)^{1-n} \times time^{-1}\\ \]\end{tabular} \\ \hline

Overleaf 告诉我我犯了一个错误 - 有人能调试一下我的代码吗？我在某个地方犯了一个错误，但似乎不知道它在哪里。

Answer 1

@samcarter_is_at_topanswers.xyz 答案的一个小版本。更改的是

• 表格样式，
• 软件包amsmath并作为库siunitx加载tabularray
• 所有关于表格样式的说明都收录在表格序言中

tabularray它可以与本地安装的软件包版本 2022C 以及现在在 Overleaf 上安装的软件包版本（已测试）配合良好。

Answer 2

主要问题是您不能\[...\]在单元格内使用。您可以改用$\displaystyle ...$，但我认为使用该包会获得更好的结果tabularray。

\text{...}您也在代码中使用，但是amsmath您的序言中缺少该包。

最后，您可能需要查看一下软件包，siunitx以便正确地将您的单位设置为直立字体。
