投影机中的圆形表格单元格

Question

我想像图中所示那样圈出单元格。如何在投影仪框架内执行此操作？

我跟着这个类似的问题但不知道如何使圆圈变粗并呈红色。

\documentclass{beamer}

\usepackage{tikz}
\usetikzlibrary{fit,shapes.geometric}

\begin{document}
\begin{frame}{}
    \begin{table}
        \begin{tabular}{l | c | c | c | c }
            Competitor Name & Swim & Cycle & Run & Total \\
            \hline \hline
            John T & 13:04 & 24:15 & 18:34 & 55:53 \\ 
            Norman P & 8:00 & 22:45 & 23:02 & 53:47\\
            Alex K & 14:00 & 28:00 & n/a & n/a\\
            Sarah H & 9:22 & 21:10 & 24:03 & 54:35 
        \end{tabular}
        \caption{Triathlon results}
    \end{table}
\end{frame}
\end{document}

Answer 1

tikz按照说明使用这个答案是“如何在方程和矩阵中添加箭头？”：

• \tikznode在序言中定义。
• 为想要用来装饰的文本分配一个标签\tikznode。
• 添加tikzpicture带有装饰的环境（使用上一步中的标签）。
• 不要忘记至少运行两次 LaTeX 以确保位置正确。

\documentclass{beamer}
\usepackage{tikz}
\newcommand\tikznode[3][]{%
  \tikz[remember picture,baseline=(#2.base)]
    \node[minimum size=0pt,inner sep=0pt,#1](#2){#3};%
}
\begin{document}
\begin{frame}
  \begin{tabular}{l | c | c | c | c }
    Competitor Name & Swim & Cycle & Run & Total \\
    \hline\hline
    John T & 13:04 & 24:15 & 18:34 & 55:53 \\ 
    Norman P & 8:00 & 22:45 & 23:02 & 53:47\\
    Alex K & 14:00 & \tikznode{alex}{28:00} & n/a & n/a\\
    Sarah H & 9:22 & 21:10 & 24:03 & 54:35 
  \end{tabular}
  \begin{tikzpicture}[remember picture,overlay]
    \draw[red,very thick] (alex) circle[x radius=8mm,y radius=4mm]; 
  \end{tikzpicture}
\end{frame}
\end{document}

Answer 2

通过使用tikzmark图书馆。基于突出显示单元格：

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{fit,             
                tikzmark,       % <---
                shapes.geometric}  
\tikzset{FIT/.style = {%
    ellipse, draw=red, thick, inner xsep=0pt, fit=#1}
        }
\usepackage{hhline}

\begin{document}
\begin{frame}
\frametitle{Use of \texttt{tikzmark} library}
    \begin{table}
    \centering
\begin{tabular}{l | c | c | c | c }
Competitor Name
            & Swim  & Cycle                     & Run   & Total \\
    \hhline{=:=:=:=:=}
John T      & 13:04 & 24:15                     & 18:34 & 55:53 \\
Norman P    & 8:00  & 22:45                     & 23:02 & 53:47 \\
Alex K      & 14:00 & \tikzmarknode{a}{28:00}   & n/a   & n/a   \\
Sarah H     & 9:22  & 21:10                     & 24:03 & 54:35
\end{tabular}
    \begin{tikzpicture}[overlay,remember picture]
\node[FIT=(a)] {};
    \end{tikzpicture}
\caption{Table}
    \end{table}
\end{frame}
\end{document}

Answer 3

使用{NiceTabular}和nicematrixTikZ 来绘制省略号。

\documentclass{beamer}
\usepackage{nicematrix}
\usepackage{tikz}
\usetikzlibrary{fit,shapes.geometric}  
\tikzset{FIT/.style = {ellipse, draw=red, thick, inner xsep=0pt, fit=#1} }

\begin{document}

\begin{frame}
\frametitle{Use of the \texttt{nicematrix}}
\begin{table}
\centering
\begin{NiceTabular}{l | c | c | c | c }
Competitor Name
            & Swim  & Cycle   & Run   & Total \\
\Hline\Hline
John T      & 13:04 & 24:15   & 18:34 & 55:53 \\
Norman P    & 8:00  & 22:45   & 23:02 & 53:47 \\
Alex K      & 14:00 & 28:00   & n/a   & n/a   \\
Sarah H     & 9:22  & 21:10   & 24:03 & 54:35 \\
\CodeAfter
  \tikz \node[FIT=(4-3)] {} ;
\end{NiceTabular}
\caption{Table}
\end{table}
\end{frame}

\end{document}

Answer 4

因为我不知道\h命令是什么，所以我用几个\hlines 替换了它。你可以用包圈出单元格内容circledsteps：

\documentclass[svgnames]{beamer}
\usepackage{circledsteps}
\begin{document}

\begin{frame}{title}

\begin{table}
\color{NavyBlue}
\begin{tabular}{l | c | c | c | c }
Competitor Name & Swim & Cycle & Run & Total \\
\hline\hline
John T & 13:04 & 24:15 & 18:34 & 55:53 \\
Norman P & \phantom{0}8:00 & 22:45 & 23:02 & 53:47\\
Alex K & 14:00 & \Circled[outer color=IndianRed, inner ysep=8pt]{28:00} & n/a & n/a\\
Sarah H & \phantom{0}9:22 & 21:10 & 24:03 & 54:35
\end{tabular}
\caption{Triathlon results}
\end{table}

\end{frame}

\end{document}
