Beamer 框架中的诗句

Question

我怎样才能在投影仪框架中存档编号的诗歌行？

\documentclass{beamer}
\usepackage{verse}

\usetheme{Madrid}
\usecolortheme{beaver}

\begin{document}
    \begin{frame}
        \poemlines{2}
        \begin{block}{essen}
            \begin{verse}
                Sunset and evening star, \\
                  And one clear call for me! \\
                And may there be no moaning of the bar, \\
                  When I put out to sea, \\!
            \end{verse}
        \end{block}
    \end{frame}
\end{document}

我认为行号太靠右了，但我不知道如何处理这个问题。

谢谢回答。

Answer 1

编号诗的行数位于右边距。您可以使用它columns来减小行宽并模拟边距：

\documentclass{beamer}
\usepackage{verse}

\usetheme{Madrid}
\usecolortheme{beaver}

\begin{document}
\begin{frame}
  \poemlines{2}
  \begin{block}{essen}
    \begin{columns}[onlytextwidth]
      \column{.9\linewidth}
      \begin{verse}
        Sunset and evening star, \\
        And one clear call for me! \\
        And may there be no moaning of the bar, \\
        When I put out to sea, \\!
      \end{verse}
      \column{.1\linewidth}
    \end{columns}
  \end{block}

  \begin{columns}[onlytextwidth]
    \column{.9\linewidth}
    \begin{block}{essen}
      \begin{verse}
        Sunset and evening star, \\
        And one clear call for me! \\
        And may there be no moaning of the bar, \\
        When I put out to sea, \\!
      \end{verse}
    \end{block}
    \column{.1\linewidth}
  \end{columns}
\end{frame}
\end{document}
