浮动表格和 tikz 图形的对齐

浮动表格和 tikz 图形的对齐

我正在尝试并排显示 tikzpicture 和表格。但我很难将它们对齐，就像表格和图形行对齐的显示对齐失败。我尝试调整链接的答案，但它不适用于 tikzpicture（我实际上使用 \input{} 从 .tikz 文件中读取图像）。理想情况下，我不想将 tikz 文件转换为 png。有人可以建议我该怎么做吗？

像这样？

在此处输入图片描述

编辑：考虑到@ John Kormylo 的宝贵评论：

[b]通过在 中添加选项，可以将图像和表格的底部对齐tablular。这样，两者的底部都有基线。

无关：我擅自建议你删除\resizebox并减少决策树中的大小级别距离和兄弟距离。此外，对于“是”和“否”，我使用\textit{...}内联数学代替并减少使用的字体大小。通过降低颜色强度，可以更好地显示树节点中的文本。所有这些（离题）更改都不会影响图中的图像位置，但会略微提高其质量。如果您不喜欢所有这些更改，您仍然可以使用原始图像的代码resizebox（不推荐），但表格和图像仍将在底部对齐。

图像代码中的所有更改均通过以下方式表示% <---：

adjustbox带有选项valign。我之所以选择是valign=b因为我不知道你想要什么，但你当然可以改变它。

\usepackage{subfig}
\usepackage{adjustbox}
\usepackage{tikz}

\usetikzlibrary{arrows,shapes,positioning,shadows,trees,patterns}

            leaf/.style={basic, rounded corners=6pt, thin,align=center, fill=blue, text width=1cm}] 
        \node [split] {$x_1<0.75$}
            child{ node [split] {$x_2<1.25$}

            child{ node [leaf] {$\omega_{01}$} edge from parent node[above right] {$yes$}}

            child{ node [leaf] {$\omega_{11}$} edge from parent node[above right] {$yes$}}
            edge from parent node[above right] {$yes$}
            };
        \end{tikzpicture}

这样做的好处是您可以tikzpicture以不同的方式加载和对齐相同内容，而无需进行修改。

            leaf/.style={basic, rounded corners=6pt, thin,align=center, fill=blue, text width=1cm}] 
        \node [split] {$x_1<0.75$}

以上内容假设您希望自由选择对齐方式。如果您确定要对齐到底部，则可以执行以下操作John Kormylo 指出，仅对齐表格。此变体有其他用途，即您可以更方便地使用 生成树forest。它允许您自动完成所有操作。

\documentclass{article}

    where n=1{edge label={node[above left,pos=0.9,font=\sffamily\small]{yes}}}{%
