表格中的 Tikzpicture

我想将 tikzpicture 置于第一列的中央。在输出中，行与行之间的图形对齐方式不同。

tikzpicture您可以在minipages中插入s

附言：您的代码中有一些错误，我已经更正了......

tikzpicture您可以在嵌套的 中插入tabular，这将提供垂直对齐。必须为单元格添加更多高度，我通过本地更改 来实现\extrarowheight。

\documentclass[12pt]{report}
\usepackage{array}
\usepackage{tikz}
\usetikzlibrary{decorations.markings}
\tikzset{vertex/.style={circle, draw, inner sep=0pt, minimum size=6pt}}
\newcommand{\vertex}{\node[vertex]}

\begin{document}
\begin{table}
\centering
\setlength{\extrarowheight}{12pt}
$\begin{array}{|c|lc|lc|lc|} 
\hline
G & \multicolumn{2}{c|}{cr(G+nK_{1})} &
    \multicolumn{2}{c|}{cr(G+P_{n})}   &
    \multicolumn{2}{c|} {cr(G+C_{n})}  \\ 
\hline 

%enter first row%
\begin{tabular}{@{}c@{}}
\begin{tikzpicture}[x=0.7cm, y=0.7cm]
    \vertex (a) at (0,0) {};
    \vertex (b) at (1,0) {};
    \vertex (c) at (0,1) {};
    \vertex (d) at (1,1) {};
\end{tikzpicture}
\end{tabular}
& Z(4,n) & n\geq 1 & Z(4,n) & n\geq 1 & Z(4,n) & n\geq 3 \\   \hline
%%%%Entering second row%%%%
\begin{tabular}{@{}c@{}}
\begin{tikzpicture}[x=0.7cm, y=0.7cm]
    \vertex (a) at (0,0) {};
    \vertex (b) at (1,0) {};
    \vertex (c) at (0,1) {};
    \vertex (d) at (1,1) {};
    \path
        (a) edge (c);
\end{tikzpicture}
\end{tabular}
& Z(4,n) & n\geq 1 & Z(4,n) & n\geq 1 & Z(4,n) & n\geq 3 \\  \hline

%%%%Entering third row%%%%
\begin{tabular}{@{}c@{}}
\begin{tikzpicture}[x=0.7cm, y=0.7cm]
    \vertex (a) at (0,0) {};
    \vertex (b) at (1,0) {};
    \vertex (c) at (0,1) {};
    \vertex (d) at (1,1) {};
    \path
        (a) edge (c)
        (b) edge (d);
\end{tikzpicture}
\end{tabular}
& Z(4,n) & n\geq 1 & Z(4,n) & n\geq 1 & Z(4,n) & n\geq 3 \\   \hline

\end{array}$

\end{table}

整个构造应该在一个table环境中，可能。不\[...\]，在这种情况下，虽然它并没有太大的区别。我改用\centering。
