Tabularx 的交叉引用和标题？

Question

\documentclass[12pt]{article}

\usepackage{float}
\usepackage{tabularx}


\title{Tabularx Test}


\begin{document}

\maketitle

\begin{center}
\begin{tabularx}{100pt}{c|c|c|}
\multicolumn{1}{c}{ } &\multicolumn{1}{c}{$\omega_1$} &\multicolumn{1}{c}{$\omega_2$} \\ 
\cline{2-3}
$a$ & 0 & 0  \\ \cline{2-3}
$b$ & $x$ & $y$   \\ \cline{2-3}
\end{tabularx}\vskip 1cm 
 \captionof{Figure}{test}
 \label{twobytwo}
 \end{center}

\end{document}

经过一番搜索，我认为 \captionof 可以与 tabularx 配合使用。但代码不起作用。我想让标题和交叉引用起作用。非常感谢！

Answer 1

该问题与tabularx

使用\captionof{table}{...}（并添加包caption）你可以编写

See the table \ref{twobytwox} or table \ref{twobytwo}.

\documentclass[12pt]{article}

\usepackage{float}
\usepackage{tabularx}

\usepackage{caption}% added <<<<<
