\phantom \begin{figure} 不起作用

Question

这为什么不起作用？

\phantom{
      \begin{figure}[H]
        \includegraphics{fig.pdf}
      \end{figure}
}

它输出

Error: Something's wrong--perhaps a missing \item.

我正在尝试做这样的事情

\begin{frame}
  \only<1>{%
    \begin{tabular}{r|ccc}
      Cool table & $a$ & $b$ & $c$ \\\hline
      $a$ & 1 & 1 & 0 \\
      $b$ & 1 & 1 & 1 \\
    \end{tabular}\\
  }
  \only<2>{%
    \begin{tabular}{r|ccc}
      Cool table & $a$ & $b$ & $c$ \\\hline
      $a$ & 1 & \color{red}1 & 0 \\
      $b$ & 1 & 1 & 1 \\
    \end{tabular}\\
  }
  \only<3>{%
    \begin{tabular}{r|ccc}
      Cool table & $a$ & $b$ & $c$ \\\hline
      $a$ & 1 & 1 & \color{red}0 \\
      $b$ & 1 & 1 & 1 \\
    \end{tabular}\\
  }
  \only<2>{%
    \begin{figure}
      \centering
      \includegraphics{../shared/arrows_0.pdf}
    \end{figure}
  }
  \only<3>{%
    \begin{figure}
      \centering
      \includegraphics{../shared/arrows_1.pdf}
    \end{figure}
  }
\end{frame}

而且我不希望表格或图片跳动。
