您需要定义C列。我的定义来自这里。

\documentclass[journal]{IEEEtran}
\usepackage{siunitx,booktabs}
\usepackage{float} %for fix the image position
\usepackage{amsmath} %% for case bracket
\pagenumbering{gobble} %%% for without page numbers

答案2

您显示的代码中存在很多问题。

  1. 您真的需要加载所有软件包吗？
  2. 你加载了几个包两次，不要这样做！
  3. 仔细查看调用包的顺序。在你的情况下，包cleveref应该最后调用。如果你想使用，请hyperref加载它前 cleveref！
  4. 对于您的表格的问题，使用的字体无关（我对其进行了评论）。
  5. C您在表格中使用的定义缺失。因为您加载了array我认为\newcolumntype{C}[1]{>{\centering\arraybackslash}m{#1}}您正在使用的内容，但您没有将其复制到代码中。如果您使用p{#1}而不是我的，m{#1}请查看下面添加的屏幕截图以了解差异！
  6. 我对您的表格做了一些漂亮的打印，以便读者可以更快地找到表格中的特殊单元格。
  7. 针对表格中的问题，我注释掉了代码中所有不需要的包。请检查加载包的不同顺序！

  8. 请注意，这\centering不适用于您在环境中使用的类table。为了直观地展示这一点，我添加了包showframe。它显示了打字区域和边距...原因是类IEEEtran使用了两列布局。然后环境table必须适合一列，但您使用的表超出了可能的范围\columnwidth。要摆脱这种情况，请使用环境table*。它跨越两列...

  9. 我发表评论是\tablesize{\footnotesize}因为它引发了错误消息comand \tablesize undefined。

  10. 您使用的命令\bf已过时，您可以改用\textbf{...}（如我在以下代码中所做的那样）。另一种方法是更改\bf​​为\bfseries。
  11. 因为您没有给我们bib文件，所以我只是在表格中评论了您对书籍等的引用（\cite）...

使用以下代码

得到结果：

结果表

table或者更好地显示文档中填充列的环境问题：

导致表格重叠列

对表使用以下代码（我使用包blindtext来生成虚拟文本来填充列）和环境table*：

\blindtext

\begin{table*}
  \centering % <========================================================
  \small
  %\tablesize{\footnotesize} % <==========================================
  \caption{Comprehension of recent and relevant work.} 
  \label{tab:litraturea}
\begin{tabular}{C{2.5cm}C{6cm}C{2.5cm}C{2.5cm}} % C
\toprule
\textbf{Methodologies}  
  & \textbf{Features} 
  & \textbf{Targets Achieved} 
  & \textbf{Limitations and Remarks} \\
\midrule
        %\hline Optimal power scheduling method for DR in HEMS is presented in \cite{9} & GA & Cost and PAR reduction & Increased system complexity \\
MILP 
  & Optimal domestic load scheduling %\cite{35} 
  & Electricity cost reduction 
  & The cost is reduced at expense of user discomfort\\
\midrule 
Greedy algorithm

  & Reduced user frustration and electricity cost

\midrule

答案3

您的代码存在一些严重问题。列C类型未定义甚至不是最严重的问题。

  • 文档IEEEtran类默认采用双列布局。您需要使用table*环境而不是table环境，以便表格内容可以安全地跨越两列。

  • 由于table*环境跨越两列，因此您不妨利用这一事实，使用tabularx环境而不是环境。我建议您对左侧列tabular使用基本列类型，对接下来的三列使用列类型。lX

  • caption已知和包subcaption与文档类不兼容IEEEtran。不要加载这些包。相反，只需依赖IEEEtran文档类提供的标题格式化算法即可。

  • 尽量让表格材料看起来更开放，主要是通过使用更少的水平线。另外，不要过度使用大胆的。当然，对于手头的表格，使用大胆的因为标题单元格可能会显得俗气，甚至有点粗俗。

  • 正如已经指出的那样这个答案，不要多次加载包。事实上，问问自己是否真的需要当前加载的所有包。下面的代码仅加载使表可编译所需的包。
