具有多个标题的表格

Question

我正在尝试获取下表，其中前两行是标题

我正在使用以下代码，但它不起作用

\PassOptionsToPackage{table, dvipsnames}{xcolor}
\documentclass[runningheads]{llncs}
\usepackage{listings}
\usepackage{xcolor}
\usepackage{siunitx} 
\usepackage{graphicx}
\begin{document}
\begin{table}[t]
    \centering
    \scriptsize
     \setlength\tabcolsep{0pt}
    \begin{tabular*}{\columnwidth}{@{\extracolsep{\fill}}
      | c |  c | c | c | c | c | c | c | }
      \hline
  \multicolumn{4}{c}{\textbf{Code Representation Approach}}&\textbf{Programming Languages} & \textbf{Code Tackling levels}  & \multicolumn{2}{c}{\textbf{Deep Learning Approach}}\\ \hline
      Tree Based Approach   & Graph Based Approach & Token Based Approach & Others & & & DL Model & Others  \\ \hline
         AST & CFG & Word Embedding & ByteCode& C& Method Level & ANN & DBN \\ \hline
         & DFG& n-grams & ASCCI & C++& Statement level & RNN & NMT \\ \hline
    \end{tabular*}
    \caption{Caption}
    \label{tab:my_label}
\end{table}
\end{document}

执行此代码后，相应的表格不匹配，最后一列被隐藏，因为表格向右移动太多

Answer 1

您可以通过以下方法将表格压缩到可用的文本宽度内：缩短列标题并允许在较长的表格条目中换行。但请注意，我必须保持\scriptsize字体大小。

在下面的 MWE 中，我还包括了以下两种替代方法，其中我将表格分成两半，每半 4 列：

最后，我添加了一个示例，说明如何使用嵌套的逐项列表呈现相同的信息：
