显示一系列树和箭头

我应该将一系列图像按顺序排列并用箭头连接起来。这就是我设法做到的： 在此处输入图片描述

使用此代码：

\begin{figure}[!htbp]

\subfloat{
\begin{forest}
    [\textbf{\(\textbf{P}\sb{id1}\)}
        [\(\textbf{\#text}\sb{id2}\)]
        [\(\textbf{B}\sb{id3}\) [\(\textbf{\#text}\sb{id4}\)]]
        [\(\textbf{\#text}\sb{id5}\)]
    ]
\end{forest}

        [\(\textbf{\#text}\sb{id5}\)]
    ]

}
\subfloat{
    $\xrightarrow{R(id4, id9)}$
}
\subfloat{

    [\textbf{\(\textbf{P}\sb{id6}\)}
        [\(\textbf{\#text}\sb{id7}\)]

        [\(\textbf{\#text}\sb{id5}\)]

\end{forest}

\subfloat{

这非常好，但我希望箭头居中对齐而不是向下。

我希望每行之间能有更多的空间。

像这样：

我怎样才能做到这一点？

我的序言部分内容：

\documentclass[a4paper, 11pt, titlepage]{book}

\usepackage[italian]{babel}
\usepackage{courier}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\usepackage{forest, adjustbox}
\usepackage{mathtools}

\usepackage{graphicx}
\usepackage{subfig}
\captionsetup[subfigure]{subrefformat=simple,labelformat=simple,listofformat=subsimple}
\renewcommand\thesubfigure{(\alph{subfigure})}

如果可能的话，我愿意继续使用该套餐子浮点型因为我的文档中有很多这样的数字，而且我不想改变所有内容。

多谢！

答案1

\subfloat为此，您不需要。所有树都可以封装在一个tabular环境中，该环境可保证相对于箭头所在的公式轴垂直居中。

我还补充说，\small这会使所有内容稍微小一些，并有助于控制尺寸。
