'tikzpicture' 和 'tabular' 的可变标题间距

Question

如果你把环境tikzpicture放在一个盒子里，它就有高度15.84369pt和深度0pt，因为参考点在底部边界。然后 TeX 应用通常的线间算法，下一条基线有距离\baselineskip。

如果tabular，则默认参考点以数学轴为中心（\vcenter用于垂直居中）。结果：高度为8.9pt，深度为3.9pt。如果的常用算法\baselineskip给出的行间距小于\lineskiplimit，则 TeX 使用\lineskip（默认为1pt）。

如果您想要相似的间距，那么可以使用可选的放置选项将参考点tabular向下移动b：

\documentclass{report}
\usepackage{tikz}

\begin{document}
  \setlength{\abovecaptionskip}{0pt}
  \begin{figure}
    \centering
    \begin{tikzpicture}
      \node[rectangle] {Some Figure};
      \draw (current bounding box.south west) rectangle (current bounding box.north east);
    \end{tikzpicture}
    \caption{A Caption}

    \vspace{1cm}

    \begin{tabular}[b]{|l|l|}
      \hline
      Nonlinear & 3.720894e-0\\ \hline
    \end{tabular}
    \caption{B Caption}
  \end{figure}
\end{document}

或者从另一个方向，tikzpicture改变的参考点，例如：

\documentclass{report}
\usepackage{tikz}

\begin{document}
  \setlength{\abovecaptionskip}{0pt}
  \begin{figure}
    \centering
    \begin{tikzpicture}[baseline=(current bounding box.center)]
      \node[rectangle] {Some Figure};
      \draw (current bounding box.south west) rectangle (current bounding box.north east);
    \end{tikzpicture}
    \caption{A Caption}

    \vspace{1cm}

    \begin{tabular}{|l|l|}   
      \hline
      Nonlinear & 3.720894e-0\\ \hline
    \end{tabular}
    \caption{B Caption}
  \end{figure}
\end{document}

可以通过以下方式实现不留任何空间的极端情况\nointerlineskip：

\documentclass{report}
\usepackage{tikz}

\begin{document}
  \setlength{\abovecaptionskip}{0pt}
  \begin{figure}
    \centering
    \begin{tikzpicture}[baseline=(current bounding box.center)]
      \node[rectangle] {Some Figure};
      \draw (current bounding box.south west) rectangle (current bounding box.north east);
    \end{tikzpicture}

    \nointerlineskip
    \caption{A Caption}

    \vspace{1cm}

    \begin{tabular}{|l|l|}
      \hline
      Nonlinear & 3.720894e-0\\ \hline
    \end{tabular}

    \nointerlineskip
    \caption{B Caption}
  \end{figure}
\end{document}
