如何在列环境中定位表格？

在我的 Beamer 幻灯片中，顶部有一张 tikzpicture。剩余的幻灯片分为两列，每列都有一个表格。

我有以下问题：

  1. 我想对齐表格顶部。我该怎么做？
  2. 我如何才能固定两列的字体大小？

答案1

使用 minipage 代替 columns 和 column 环境。在两个 minipage 之间使用 hspace{0.5cm}。在 minipage 环境命令之后，在第一个 minipage 中使用 vspace{-0.1cm}，在第二个 minipage 中使用 vspace{0.5cm}，然后编译代码，您将得到以下内容。

投影机校正

有columns一个选项，\begin{columns}[onlytextwidth,T]
