如何为带有图形的列添加标题

Question

我已将框架分为两列。每列都有图片和逐项文本。我试图在每列顶部添加标题，但不起作用。我希望在每列的顶部中央添加一个标题

\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{columns} 
    \column{0.5\textwidth}
    First Column
    \begin{tikzpicture}
    \draw[red] (0.46,0.56) ellipse (0.9cm and 0.75cm);
    \end{tikzpicture}
    \begin{itemize}
    \item 1
    \end{itemize} 

   \column{0.5\textwidth}
    Second Column
    \begin{tikzpicture}
    \draw[green] (0.46,0.56) ellipse (0.9cm and 0.75cm);
    \end{tikzpicture}
    \begin{itemize}
    \item 1
    \end{itemize} 

\end{columns}
\end{frame}
\end{document}

Answer 1

您正在与第一/第二列标题在同一行上绘图（请记住：当您简单地按下键盘LaTeX时不会添加新行）。在每列的开头添加一个可以轻松解决此问题。Return\centering

\documentclass{beamer}
\usepackage{tikz}
\begin{document}
\begin{frame}
\begin{columns} 
  \column{0.5\textwidth}\centering
    First Column\\[.2cm]
    \begin{tikzpicture}
    \draw[red] (0.46,0.56) ellipse (0.9cm and 0.75cm);
    \end{tikzpicture}
    \begin{itemize}
    \item 1
    \item 2
    \end{itemize} 
  \column{0.5\textwidth}\centering
    Second Column\\[.2cm]    
    \begin{tikzpicture}
    \draw[green] (0.46,0.56) ellipse (0.9cm and 0.75cm);
    \end{tikzpicture}
    \begin{itemize}
    \item 1
    \item 2
    \end{itemize} 
\end{columns}
\end{frame}
\end{document}
