我尝试使用 tikzmark 做两件不同的事情，虽然每件事单独做都可以，但当我合并每件事的 latex 代码时，我收到错误。我认为这与我使用 tikzmark 的方式有关，但不确定。
第一段代码在矩阵中的数字周围绘制方框，运行正常，如下所示：
\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage{booktabs}
\usepackage{pgfplots}
\usepackage{tikz}
\usepackage{kbordermatrix}
\usetikzlibrary{arrows.meta,patterns,calc}
\newcommand{\tikzmark}[1]{\tikz[overlay,remember picture] \node (#1) {};}
\newcommand{\DrawBox}[4][]{%
\tikz[overlay,remember picture]{%
\coordinate (TopLeft) at ($(#2)+(-0.2em,0.9em)$);
\coordinate (BottomRight) at ($(#3)+(0.2em,-0.3em)$);
%
\path (TopLeft); \pgfgetlastxy{\XCoord}{\IgnoreCoord};
\path (BottomRight); \pgfgetlastxy{\IgnoreCoord}{\YCoord};
\coordinate (LabelPoint) at ($(\XCoord,\YCoord)!0.5!(BottomRight)$);
%
\draw [red,#1] (TopLeft) rectangle (BottomRight);
\node [below, #1, fill=none, fill opacity=1] at (LabelPoint) {#4};
}
}
\begin{document}
%Now Drawbox thing
\begin{equation} \label{eq:ODP all terms matrix}
\kbordermatrix{\mbox{cells} & (1,2) & (2,1) & (2,2)\\
(1,2)&\tikzmark{leftx}205.1354\tikzmark{rightx} & 0.0000 & 102.5677\\
(2,1)&0.0000 & \tikzmark{lefty}286.1821 & 57.2364 \\
(2,2)&102.5677 & 57.2364 & 206.9669\tikzmark{righty}
}
\end{equation}
\DrawBox[thick, black,dashed,fill=gray, fill opacity=0.3]{leftx}{rightx}{}
\DrawBox[thick, black, dashed,fill=gray,fill opacity=0.3]{lefty}{righty}{}
\end{document}
第二段代码在表格下方绘制一些箭头，同样可以正常工作（感谢用户 Bordaigorl）：
\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage{booktabs}
\usepackage{pgfplots}
\usepackage{tikz}
\usetikzlibrary{tikzmark,arrows.meta,patterns,calc}
\newcommand\DrawArrow[4][]{
\begin{tikzpicture}[
remember picture,
overlay,
arr/.style={draw=gray,line width=2pt, {-latex}, #1},
xshift=1em,
yshift=-3ex,
]
\draw[arr]
([xshift=1ex]pic cs:#2)
to[out=-50,in=-150,looseness=1.0] node[below=0pt] {#4}
([xshift=-1ex]pic cs:#3);
\end{tikzpicture}
}

\newcommand{\tikzmark}[1]{\tikz[overlay,remember picture] \node (#1) {};}我认为这一定与在第一段代码中使用，然后\usetikzlibrary{tikzmark,arrows.meta,patterns,calc}在第二段代码中使用有关，所以我想可能有一个简单的解决方案，但到目前为止它让我失望了。有人能帮忙吗？
答案1
您已定义 tikzmark 两次。
原始方式
\newcommand{\tikzmark}....
（我认为是从这个网站上的一个答案来的）
然后后来打包的方式
\usetikzlibrary{tikzmark,...
现在您只需要 tikz 库版本。
那么你需要适应使用pic坐标的新版本
\coordinate (TopLeft) at ($(pic cs:#2)+(-0.2em,0.9em)$);
\coordinate (BottomRight) at ($(pic cs:#3)+(0.2em,-0.3em)$);
