我对 LaTeX 文档还不太熟悉，在引用表格时遇到了问题。之前我在 Atom.io 编辑器中编译和构建，最近切换到了 VS Code。之前确实可以正常工作，但现在引用表格时出错了！
控制台一直说
第 2 页上的引用“tab:table1”未定义。
我不明白为什么以前这个方法有效，而现在却无效了？
它体现的???是\ref价值。
以下是此问题重现的最小代码。我IEEEtran为我的文档使用了模板。
\documentclass[conference,compsoc]{IEEEtran}
\begin{document}
\section{Introduction}
See \ref{tab:table1}\.
\begin{table}[ht] {\renewcommand\arraystretch{1.25}
\begin{tabular}{|l|l|l|l|} \hline
\bf Task & \bf Assignee & \bf \multicolumn{1}{l}{Description} \\ \hline
Project Manager & Alice & \multicolumn{1}{p{3.3cm}|}{\raggedright Schedule overall development plan and assign proper jobs to team members} \\ \hline
Consumer & Bob & \multicolumn{1}{p{3.3cm}|}{\raggedright Test and try out a prototype application, gather the potential improvement} \\ \hline
User & Chris & \multicolumn{1}{p{3.3cm}|}{\raggedright Gather basic feature requirement for this project by asking qeustioaires the eldery near the university.} \\ \hline
Developer & Daniel & \multicolumn{1}{p{3.3cm}|}{\raggedright Prepare a development environment for this project and build up the application} \\ \hline
\end{tabular}} \\
\caption{Task distribution for each participants of this project}
\label{tab:table1}
\end{table}
\end{document}

您必须至少编译两次文档才能确保引用正确。您的代码在 Overleaf 上运行良好。
不过，我建议你加载包聪明人，这将帮助你获得更好的参考。我还加载了包大批。
我还清理了您的代码，将弃用的命令\bf\ 更改为\bfseries并将第三列更改为 -column p。此外，您定义了四列，但只使用了三列。因此，我删除了第四列。
我还添加了示例 2，其中我使用书签得到一个更漂亮的表格，没有任何垂直线。除非这是你的出版商的要求，否则我会把标题移到表格上方，并使用包标题格式化。此外，我建议使用三部分表，以便将标题和表格在表格的右边距正确对齐（此外，三部分表正确处理表格注释）。
