tikz 图中使用的文本与箭头重叠

Question

我有以下代码

\documentclass[tikz,border=5mm]{standalone}
\usepackage{xcolor}
\begin{document}
\usetikzlibrary{matrix}
\begin{tikzpicture}
  \matrix (m) [matrix of math nodes,
    nodes in empty cells,nodes={minimum width=5ex,
    minimum height=5ex,outer sep=-5pt},
    column sep=1ex,row sep=1ex]{
            &     &     &     &  &  &  &  & \\
          \vdots     &  \vdots   &   \vdots  &   \vdots  & \cdots & \vdots & \vdots & \vdots & \underline{E^k\textsf{ page}}\\
          k     &  H_{k}(\Omega S^k)  &  0   &  0   & \cdots & 0 & H_{k}(\Omega S^k) & 0 & \cdots\\
          k-1     &  H_{k-1}(\Omega S^k)  &  0   &  0   & \cdots & 0 & H_{k-1}(\Omega S^k) & 0 & \cdots\\
          k-2     &   H_{k-2}(\Omega S^k)  &  0   &  0   & \cdots & 0 & H_{k-2}(\Omega S^k) & 0 & \cdots\\
          \vdots     &  \vdots  &   \vdots  &   \vdots  & \cdots & \vdots & \vdots & \vdots & \cdots\\
          3     &   H_3(\Omega S^k)  &   0  &   0  & \cdots & 0 & H_3(\Omega S^k) & 0 & \cdots\\
          2     &   H_2(\Omega S^k)  &  0   &  0   & \cdots & 0 & H_2(\Omega S^k) & 0 & \cdots\\
          1     &   H_1(\Omega S^k)  &  0  & 0 & \cdots & 0 & H_1(\Omega S^k) & 0 & \cdots\\
          0     &  H_0(\Omega S^k)  & 0 &  0  & \cdots & 0 & H_0(\Omega S^k) &0 & \cdots\\
    \quad\strut &   0  &  1  &  2  & \cdots & k-1 & k & k+1 & \cdots \strut \\};
\draw[thick, ->] (m-11-1.east) -- (m-1-1.east) ;
\draw[thick, ->] (m-11-1.north) -- (m-11-9.north) ;
\end{tikzpicture}
\end{document}

输出结果如下：

现在，正如您在该图像的左上角所看到的，“k-2”和“k-1”与“垂直轴”重叠。我怎样才能使这两个东西不重叠？

Answer 1

我会右对齐第一列的节点（因为它们看起来像是标签），增加列 sep，这是通过以下方式实现的

column 1/.style={nodes={text width=width("$k-2$"),align=right},column sep=2ex},

并移动轴。

\documentclass[tikz,border=5mm]{standalone}
\usepackage{xcolor}
\begin{document}
\usetikzlibrary{matrix}
\begin{tikzpicture}
  \matrix (m) [matrix of math nodes,
    nodes in empty cells,nodes={minimum width=5ex,
    minimum height=5ex,outer sep=-5pt},column sep=1ex,row sep=1ex,
    column 1/.style={nodes={text width=width("$k-2$"),align=right},column sep=2ex},
   ]{
            &     &     &     &  &  &  &  & \\
          \vdots     &  \vdots   &   \vdots  &   \vdots  & \cdots & \vdots & \vdots & \vdots & \underline{E^k\textsf{ page}}\\
          k     &  H_{k}(\Omega S^k)  &  0   &  0   & \cdots & 0 & H_{k}(\Omega S^k) & 0 & \cdots\\
          k-1     &  H_{k-1}(\Omega S^k)  &  0   &  0   & \cdots & 0 & H_{k-1}(\Omega S^k) & 0 & \cdots\\
          k-2     &   H_{k-2}(\Omega S^k)  &  0   &  0   & \cdots & 0 & H_{k-2}(\Omega S^k) & 0 & \cdots\\
          \vdots     &  \vdots  &   \vdots  &   \vdots  & \cdots & \vdots & \vdots & \vdots & \cdots\\
          3     &   H_3(\Omega S^k)  &   0  &   0  & \cdots & 0 & H_3(\Omega S^k) & 0 & \cdots\\
          2     &   H_2(\Omega S^k)  &  0   &  0   & \cdots & 0 & H_2(\Omega S^k) & 0 & \cdots\\
          1     &   H_1(\Omega S^k)  &  0  & 0 & \cdots & 0 & H_1(\Omega S^k) & 0 & \cdots\\
          0     &  H_0(\Omega S^k)  & 0 &  0  & \cdots & 0 & H_0(\Omega S^k) &0 & \cdots\\
    \quad\strut &   0  &  1  &  2  & \cdots & k-1 & k & k+1 & \cdots \strut \\};
\draw[thick, ->] ([xshift=2ex]m-11-1.east) -- ([xshift=2ex]m-1-1.east) ;
\draw[thick, ->] ([yshift=1ex]m-11-1.north) -- ([yshift=1ex]m-11-9.north) ;
\end{tikzpicture}
\end{document}
