矩阵与另一个矩阵行对齐

Question

相对于第二行+行放置矩阵似乎无法正常工作，就好像outer sep没有设置为 0 一样。我放置了一个 x 坐标节点，我希望新矩阵左上角与第一个矩阵第二行右上角的高度相同。但垂直和水平方向都有间隙。

\documentclass[a4paper]{article}
\usepackage[verbose,vmargin=30mm,hmargin=20mm]{geometry}

\usepackage{tikz,tikzpagenodes}
\usetikzlibrary{positioning, matrix,calc}

\tikzset{
  texttable/.style={row sep=-\pgflinewidth, 
                 column sep=-\pgflinewidth,outer sep=0pt,
                      nodes={anchor=center,outer sep=0pt,draw,
                 text width=#1,text depth=.5ex,text height=10pt, font=\large}}}

\setlength{\parindent}{0pt}

\begin{document}
\begin{tikzpicture}

    \matrix at (0,0) [matrix of nodes, nodes in empty cells,
    matrix anchor=north west,
    texttable={2cm}, align=right] (tb)
    {
    abc & \node (c) {def};\\
    ghi & \node (d) {jkl};\\
    mno & pqr\\
    stu & vwx\\
    };

    \coordinate [label=right:$A$] (ref) at ($(.5\textwidth,0)+(0mm,-3mm)$);
    \fill (ref) circle (1pt);
    \draw [blue] (d.north east) -- ++(60mm,0);
    \draw [blue] (ref) -- ++(0mm,-15mm);
    \matrix at (ref |- d.north east) [matrix of nodes, nodes in empty cells,
    matrix anchor=north west,
    texttable={2cm}, align=right] (tb2)
    {
    ABC & DEF\\
    GHI & JKL\\};
\end{tikzpicture}

\end{document}

Answer 1

尽管我提出了上述意见，但我发现通过转移第二个矩阵的锚点来作弊并不愉快。

实际上，矩阵有自己的inner sep，您可以将其设置为 0pt。然后，您必须将inner sep节点设置为不同的大小。

我认为它应该像这样工作：

\documentclass[a4paper]{article}
\usepackage[verbose,vmargin=30mm,hmargin=20mm]{geometry}

\usepackage{tikz,tikzpagenodes}
\usetikzlibrary{positioning, matrix,calc}

\tikzset{
  texttable/.style={row sep=-\pgflinewidth, 
                 column sep=-\pgflinewidth,outer sep=0pt,
                      nodes={anchor=center,outer sep=0pt,draw,
                 text width=#1,text depth=.5ex,text height=10pt, font=\large}}}

\setlength{\parindent}{0pt}

\begin{document}
\begin{tikzpicture}

    \matrix at (0,0) [matrix of nodes, nodes in empty cells,
    matrix anchor=north west, nodes={inner sep=3pt},
    texttable={2cm}, align=right] (tb)
    {
    abc & \node (c) {def};\\
    ghi & \node (d) {jkl};\\
    mno & pqr\\
    stu & vwx\\
    };

    \coordinate [label=right:$A$] (ref) at ($(.5\textwidth,0)+(0mm,-3mm)$);
    \fill (ref) circle (1pt);
    \draw [blue] (d.north east) -- ++(60mm,0);
    \draw [blue] (ref) -- ++(0mm,-15mm);
    \matrix at (ref |- d.north east) [matrix of nodes, nodes in empty cells,
    matrix anchor=north west, inner sep=0pt,nodes={inner sep=3pt},
    texttable={2cm}, align=right] (tb2)
    {
    ABC & DEF\\
    GHI & JKL\\};
\end{tikzpicture}

\end{document}

对于第二个矩阵，似乎inner sep=0pt不是精确的设置。相反，最好使用inner sep=-0.5\pgflinewidth，这样线条就会完全重合，如下图所示：
