表格中垂直居中的列分隔符

Question

我想在 中垂直居中自定义列分隔符tabular。我试过

 \begin{tabular}{c @{ $\vcenter{\rightarrow}$ } c @{ $\vcenter{\rightarrow}$ } c}...\end{tabular}

无济于事。其他搜索导致的答案指向如何在列内垂直居中内容，但没有指向实际的列分隔符本身。我的最小工作示例产生了以下结果：

而我想要的是（大约）这个：

与往常一样，如果您知道没有使用tabular或与我的实现有很大不同的解决方案，欢迎提出。也许我应该不使用列分隔符，而只是垂直居中所有列。

这是我的最小工作示例：

\begin{tabular}{c @{ $\rightarrow$ } c @{ $\rightarrow$ } c}

\begin{tikzpicture}[level/.style={level distance=8mm,sibling distance=25mm/#1}]

    child {node [circle,draw] {7}

        child {node [circle,draw] {4}}
        }
    child {node [circle,draw] {7}
        child {node [circle,draw] {13}}
        }
    }

添加为所有s 的baseline={(current bounding box.center)}选项tikzpicture

\begin{tikzpicture}[baseline={(current bounding box.center)},level...

代码：

\documentclass[letterpaper]{article}
\usepackage{tikz}
\usepackage[letterpaper, top=2.54cm, bottom=2.54cm, left=2.54cm, right=2.54cm]{geometry}

\begin{document}

\begin{tabular}{c @{ $\rightarrow$ } c @{ $\rightarrow$ } c}

\begin{tikzpicture}[baseline={(current bounding box.center)},level/.style={level distance=8mm,sibling distance=25mm/#1}]
\node [circle,draw]{17}
child {node [circle,draw] {9}
    child {node [circle,draw] {7}
        child {node [circle,draw] {3}}
        child {node [circle,draw] {4}}
        }
    child {node [circle,draw] {7}
        child {node [circle,draw] {13}}
        }
    }
child {node [circle,draw] {12}
    child {node [circle,draw] {9}}
    child {node [circle,draw] {5}}
    };
\end{tikzpicture} &

\begin{tikzpicture}[baseline={(current bounding box.center)},level/.style={level distance=8mm,sibling distance=25mm/#1}]
\node [circle,draw]{17}

    child {node [circle,draw] {7}
        child {node [circle,draw] {3}}
        child {node [circle,draw] {4}}
        }
    child {node [circle,draw] {13}
        child {node [circle,draw] {7}}
        }
