在投影仪列中底部对齐数字

Question

我尝试将提供的 MWE 中的图 A 和 C 对齐，但失败了。有人知道怎么做吗？

\documentclass{beamer}

\mode<presentation> {
\usetheme{Madrid}
}


\usepackage{graphicx}
\usepackage{booktabs}
\usepackage{mwe}

\begin{document}

\section{First Section} 

\subsection{Measurement methods}
\begin{frame}

\begin{columns}
    \column{.5\linewidth}
    \textbf{Connections}
    \begin{itemize}
        \item Direct connection to unknown system
        \item Series connection between source and load
        \item Parallel connection between source and load 
    \end{itemize}
    \vspace{\fill}
    \null
    \vfill
    \begin{figure}[b]
         \centering
         \includegraphics[width=.6\textwidth]{example-image-a}
        \caption{}
        \label{fig:imu}
    \end{figure}

    \column{.5\linewidth}
    \begin{figure}
         \centering
         \includegraphics[width=.6\textwidth]{example-image-b}
        \caption{}
        \label{fig:voltage}
    \end{figure}
    \begin{figure}
         \centering
         \includegraphics[width=.6\textwidth]{example-image-c}
        \caption{}
        \label{fig:current}
    \end{figure}

\end{columns}
\end{frame}

\end{document}

Answer 1

你\begin{columns}[b]将获得底部对齐的列。

无关：

• 你不需要\usepackage{graphicx}使用 beamer

• 您的列太宽，因为列之间有一些空隙。请缩小它们（例如.48\textwidth）或指定\begin{columns}[b,onlytextwidth]

• 图形的浮动选项，例如在\begin{figure}[b]没有浮点数的文档类中没有意义。

为了仅将下方的两幅图像对齐在底部，同时保持文本和另一幅图​​像的顶部对齐，请将其拆分为多个coloumns环境：

\usepackage{booktabs}
\usepackage{mwe}

\begin{document}

          \item Series connection between source and load
          \item Parallel connection between source and load 
      \end{itemize}
    \end{column}
    \begin{column}{.48\textwidth}
    \begin{figure}
