如何将 tikzpicture 定位在 tabularray 单元格的垂直中间？

Question 1

该解决方案将\struttikzpicture 置于中心，然后使用其基线。

\documentclass{article}

\usepackage{tabularray}
\usepackage{tikz}

\newcommand{\resultgraphproportion}[3]{\fpeval{(#3-#1)/(#2-#1)}}

\newcommand{\resultgraphheight}{0.5}
\NewDocumentCommand{\showresultgraphT}{}{
    \begin{tikzpicture}[baseline=(phantom.base)]
        \draw[fill=red] (0,0) rectangle (1,\resultgraphheight);
        \node[gray, inner sep=0pt] at (0,-0.1) {\tiny 20};
        \node[inner sep=0pt] (phantom) at (current bounding box.center) {\strut};
    \end{tikzpicture}
}

\begin{document}
    \begin{tblr}{lcc}
        \hline
        abc &   \showresultgraphT & great \\
        \hline
    \end{tblr}
\end{document}

        abc &   \showresultgraphT & great \\
        \hline
    \end{tblr}
\end{document}

Question 2

您需要使用图像选项将图像基线位置移动到其垂直中心baseline=(current bounding box.center)：

\documentclass{article}

\usepackage{tabularray}
\usepackage{tikz}
\newcommand{\resultgraphproportion}[3]{\fpeval{(#3-#1)/(#2-#1)}}

\newcommand{\resultgraphheight}{0.5}
\NewDocumentCommand{\showresultgraphT}{}{
    \begin{tikzpicture}[baseline=(current bounding box.center)]
        \draw[fill=red] (0,0) rectangle (1,\resultgraphheight);
        \node[gray] at (0,-0.1) {\tiny 20};
    \end{tikzpicture}
}

\begin{document}
    \begin{tblr}{lcc}
        \hline
        abc &   \showresultgraphT & great \\
        \hline
    \end{tblr}
\end{document}

编辑：
关于您的评论：

图形肯定是垂直居中的......
要看到这一点，只需用灰色文本在节点周围绘制边框：

\documentclass{article}
\usepackage{tabularray}
\usepackage{tikz}
\newcommand{\resultgraphproportion}[3]{\fpeval{(#3-#1)/(#2-#1)}}

\newcommand{\resultgraphheight}{0.5}
\NewDocumentCommand{\showresultgraphT}{}{
    \begin{tikzpicture}[baseline=(current bounding box.center)]
        \draw[fill=red] (0,0) rectangle (1,\resultgraphheight);
        \node[draw, gray, font=\tiny] at (0,-0.1) {20};
    \end{tikzpicture}
}

\begin{document}
    \begin{tblr}{hlines,
                 colspec = {lcc},
                 }
        abc &   \showresultgraphT & great \\
    \end{tblr}
\end{document}

现在的结果是：

如果您希望第二个节点内容（编号 20）和底部表格之间的垂直距离与\hline橙色框和顶部之间的垂直距离相同\hline，那么您需要重新设计图像：删除节点内容和其边框之间的垂直分隔，并手动对齐其基线，如下所示：

\documentclass{article}
\usepackage{tabularray}
\usepackage{tikz}
\newcommand{\resultgraphproportion}[3]{\fpeval{(#3-#1)/(#2-#1)}}

\newcommand{\resultgraphheight}{0.5}
\NewDocumentCommand{\showresultgraphT}{}{
    \begin{tikzpicture}[baseline=(([yshift=3pt] current bounding box.base)}] % <--- changed
        \draw[fill=red] (0,0) rectangle (1,\resultgraphheight);
        \node[inner ysep=0pt, % <--- added
              gray, font=\tiny] at (0,-0.1) {20};
    \end{tikzpicture}
}

\begin{document}
    \begin{tblr}{hlines,
                 colspec = {lcc},
                 }
        abc &   \showresultgraphT & great \\
    \end{tblr}
\end{document}

现在图像和文本到行边框之间的垂直距离相同。

这就是你要找的吗？
