使用 tikz 和 reveal 突出显示文本

Question

我想要幻灯片 2 上的数字 3480 周围有一个圆角框。幻灯片 1 上有这个框。我在幻灯片 2 中使用了相同的格式以及 reveal。但我没有得到这个框。请查看代码并告诉我错误。另外，在使用 reveal 时，有没有更简单的方法来在文本周围绘制框？

Answer 1

您可以使用该hf-tikz包来突出显示某些覆盖层上的数字：

\documentclass[11pt, aspectratio=169]{beamer}

\usepackage{booktabs}
\usepackage{tikz}
\usepackage[beamer,customcolors]{hf-tikz}

\hfsetfillcolor{bg}
\hfsetbordercolor{red}

\begin{document}

\begin{frame}
  \frametitle{Highlight the minimum cost cell using tikz (Slide 2)}
  \scriptsize
  \begin{tabular}{cccccc}
    \toprule
    Order quantity & Unit price & Annual OC & Annual HC & Annual product cost & Total annual cost\\
    \midrule
    840 & $\$0.85$ & 10 & 30 & 50 & \tikzmarkin<0>{a}\$3686\tikzmarkend{a} \\
    \midrule
    1000 & $\$0.80$ & 20 & 40 & 45 & \tikzmarkin<2->{b}\$3480\tikzmarkend{b} \\
    \bottomrule
  \end{tabular}
\end{frame}
