Overfull \hbox with a tabular TikZ

Question

Compiling my .tex file in TeXnicCenter,

\documentclass[12pt]{article}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{tikz}

\usetikzlibrary{arrows.meta,decorations.markings}

\tikzset{->-/.style={semithick,decoration={
        markings,
        mark=at position .52 with {\arrow{Stealth[length=2.5mm]}}},
        postaction={decorate}}}

\tikzset{--<--/.style={semithick,decoration={
        markings,
        mark=at position .28 with {\arrow{Stealth[length=2.5mm]}}},
    postaction={decorate}}}


\begin{document}

\begin{tabular}{cp{1cm}c}
$A_1=\begin{pmatrix}
1 & 1 \\
1 & 1
\end{pmatrix}$; &  &  
$\Gamma(A_1)\equiv \;\;\;\;\;$  

\begin{minipage}{1cm}

\begin{tikzpicture}[scale=0.725]

    \coordinate [label=below left:$P_1$] (p1) at (0,0);
    \coordinate [label=below right:$P_2$] (p2) at (6cm,0);

    \filldraw (p1) circle [radius=0.08cm]
              (p2) circle [radius=0.08cm];

    \draw[->-] (0,0) to [bend left] (6cm,0);

    \draw[->-] (p1) to [bend left] (p2);

    \draw[->-] (p2) to [bend left] (p1);

    \draw[--<--,rotate=60] (p2) arc (360:0:-1cm and -0.5cm);

    \draw[--<--,rotate=120] (p1) arc (0:360:-1cm and -0.5cm);

\end{tikzpicture}

\end{minipage}

\end{tabular}


\end{document}

you get 1 bad box and the following message in Build Output:

pdflatex> Overfull \hbox (147.05411pt to wide) in paragraph at line 50--51

How can I get rid of them without removing the tabular?

you declare the width of the minipage to be 1cm, however image inside is at least 6cm wide. consequently you receive mentioned warning. welcome to tex.se! — Zarko, May 16 '18 at 15:12

You do not need the minipage, I think. The complaint was because the minipage was not wide enough to fit the picture, as pointed out by Zarko.

\documentclass[12pt]{article}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{tikz}

\usetikzlibrary{arrows.meta,decorations.markings}

\tikzset{->-/.style={semithick,decoration={
        markings,
        mark=at position .52 with {\arrow{Stealth[length=2.5mm]}}},
        postaction={decorate}}}

\tikzset{--<--/.style={semithick,decoration={
        markings,
        mark=at position .28 with {\arrow{Stealth[length=2.5mm]}}},
    postaction={decorate}}}


\begin{document}

\begin{tabular}{cp{1cm}c}
$A_1=\begin{pmatrix}
1 & 1 \\
1 & 1
\end{pmatrix}$; &  &  
$\Gamma(A_1)\equiv \;\;\;\;\;$  

%\begin{minipage}{1cm}

\begin{tikzpicture}[scale=0.725,baseline=(p1)]

    \coordinate [label=below left:$P_1$] (p1) at (0,0);
    \coordinate [label=below right:$P_2$] (p2) at (6cm,0);

    \filldraw (p1) circle [radius=0.08cm]
              (p2) circle [radius=0.08cm];

    \draw[->-] (0,0) to [bend left] (6cm,0);

    \draw[->-] (p1) to [bend left] (p2);

    \draw[->-] (p2) to [bend left] (p1);

    \draw[--<--,rotate=60] (p2) arc (360:0:-1cm and -0.5cm);

    \draw[--<--,rotate=120] (p1) arc (0:360:-1cm and -0.5cm);

\end{tikzpicture}

%\end{minipage}

\end{tabular}


\end{document}

And actually I would not use a tabular either. And I add some other features, some of which are suggested by Zarko (Thanks!).

Other options to center the tikzpicture include wrapping it into \vcenter{\hbox{...}}.

@Zarko Thanks! There are additional improvements possible, I think, but the output is already decent, so why changing a code the OP created and is comfortable with? — , May 16 '18 at 15:38
you are right. actually, i'm surprised that y comment appear. at writing it some magic happens and and i lost it on my screen, so i believe, that it is not uploaded ... anyway, i will delete it now. — Zarko, May 16 '18 at 15:43
@IgnacioT I guess you only need to make it wider, e.g. \begin{minipage}{7cm} or so. But why do you want to keep it? — , May 16 '18 at 16:10
