通过箭头连接表格单元格中的框

Question

我正在尝试创建一个包含三列的表格：

1. 自上而下的流程图
2. 图表
3. 人物

我使用框架绘制了流程图中的步骤parbox：

\fbox{\parbox{20mm}{
    \centering
    Text
}}

为了连接这些盒子，我尝试使用 tikzmark 包手动设置坐标。

但我怎样才能确保箭头是：

1. 框下方/上方居中
2. 连接至箱子框架吗？

\documentclass[12pt,a4paper]{article}

\usepackage{tikz}
\usetikzlibrary{tikzmark}

\usepackage[export]{adjustbox} % for the valign=c option

\usepackage[column=0]{cellspace}
\setlength{\cellspacetoplimit}{\tabcolsep}
\setlength{\cellspacebottomlimit}{\cellspacetoplimit}


\begin{document}

Answer 2

这是否满足要求 - 我在框之间添加了一行，以便可以看到箭头 - 您还可以通过调整坐标来试验箭头的位置(-1,0)- hline 已被注释掉以获得干净的表格，您可以根据需要将它们放回去

\documentclass[12pt,a4paper]{standalone}

\usepackage{tabularx}
\usepackage{tikz}
\usetikzlibrary{tikzmark,positioning,calc}

\begin{document}    
    \begin{tabularx}{\textwidth}{c|X|X|}
%        \hline
            Process Step &
            Relevant Parameters &
            Visual Representation\\
%        \hline
            \fbox{\parbox{20mm}{
                \centering
                Wire Bonding
            }} \tikzmark{a} &
            Figure &
            Image\\
%        \hline
&&\\
            \fbox{\parbox{20mm}{
                \centering
                Phosphor Deposition}} \tikzmark{b} &
            Figure &
            Image\\
        \hline
        \end{tabularx}
        \begin{tikzpicture}[overlay, remember picture]
        \draw [->,ultra thick, red] ($({pic cs:a})+(-1,0)$) -- ($({pic cs:b})+(-1,0)$);
    \end{tikzpicture}

\end{document}

可选择使用以下 tikzpicture 作为侧向箭头--

\begin{tikzpicture}[remember picture, overlay]
\draw ($(pic cs:a)+(-2pt,0pt) $) edge[bend left=60, -latex,  red,ultra thick] 
($(pic cs:b)+(-2pt,0pt)$) ;
\end{tikzpicture}
