如何为 Latex beamer 定义额外的 \caption* 类命令？

Question

beamer目前与软件包不兼容caption（如这里所述)。我想定义一个附加命令，其工作方式与\caption*该包的命令类似，即排版标题而不带标签，也不带表格/图形列表中的条目，但格式与常规\caption命令相同。重要提示：我仍然需要正常\caption命令，因此我不能只是全局重新定义\setbeamertemplate{caption}

我正在考虑

\documentclass{beamer}
\usepackage[english]{babel}
\usepackage{caption}

\begin{document}
\begin{frame}{Some title}
  \begin{table}
    \begin{tabular}{cc}
      A & B \\
      C & D \\
    \end{tabular}
    \caption{Some numbered Table and its description. Even more and more and more text.}
  \end{table}

  \begin{table}
    \begin{tabular}{cc}
      A & B \\
      C & D \\
    \end{tabular}
  \caption*{Some unnumbered Table and its description. Even more and more and more text.}
  \end{table}
\end{frame}
\end{document}

Answer 1

这是实现此目的的一种方法；\caption*继承相同的格式\caption（特别是，它具有相同的上下跳过和单行功能）：

代码：

\documentclass{beamer}
\usepackage{letltxmacro}
\usepackage{xparse}

\LetLtxMacro\oldcaption\caption

\makeatletter
\RenewDocumentCommand\caption{som}{
  \IfBooleanTF{#1}
    {
      \setbeamertemplate{caption label separator}[none]
      \def\insertcaptionname{}%
      \def\insertcaptionnumber{}%
      \def\insertcaption{#3}%
      \nobreak\vskip\abovecaptionskip\nobreak
      \sbox\@tempboxa{\usebeamertemplate**{caption}}%
      \ifdim \wd\@tempboxa >\hsize
        \usebeamertemplate**{caption}\par
      \else
      \global \@minipagefalse
        \hb@xt@\hsize{\hfil\box\@tempboxa\hfil}%
      \fi
      \nobreak\vskip\belowcaptionskip\nobreak
    }
    {\oldcaption[#2]{#3}}
}
\makeatother

\newcommand\TestTable{%
    \begin{tabular}{cc}
      A & B \\
    \end{tabular}%
}

\begin{document}

\begin{frame}{Some title}

\begin{table}
\TestTable
\caption{Some numbered Table and its description. Even more and more and more text.}
\end{table}

\begin{table}
\TestTable
\caption*{Some unnumbered Table and its description. Even more and more and more text.}
\end{table}

\begin{table}
\TestTable
\caption{Some numbered Table}
\end{table}

\begin{table}
\TestTable
\caption*{Some unnumbered Table}
\end{table}

\end{frame}

\end{document}
