Question

我想写一个代码来获取网络包结构。

        1          var         4
-------------------------------------
|   Control   |    Casa   |   Mia   |

目前我有下面的代码，但我注意到在单元格 Control 和 Casa 之间有两行而不是一行。有什么帮助吗？

\documentclass{article}

\usepackage[latin9]{inputenc}
%\usepackage[utf8x]{inputenc}
%\usepackage[spanish]{babel}
%\usepackage[spanish]{translator}
\usepackage[OT1]{fontenc}

%TikZ stuff
\usepackage{tikz}
\usepackage{pgfplots}
\usepackage{pgf}
\usetikzlibrary{shapes,arrows,automata,plotmarks,positioning} 


\begin{document}


\begin{tikzpicture}%[scale=1.5]
    \tikzstyle{every path}=[draw, font=\small]

    \node[right,draw, minimum width=2cm,minimum height=0.8cm,fill=white](b0) {Control};
    \node[right=0cm of b0, draw, minimum width=2cm,minimum height=0.8cm,fill=white](b0) {Casa};
\end{tikzpicture}

\end{document}

现在我有了这个，但图形不在中心，并且不知道如何从控制角画一条线来到达另一行的总数

\begin{figure}    
\newcommand{\size}{\linewidth}

\begin{tikzpicture}%[scale=1]
    \tikzstyle{every path}=[draw, font=\small]

    \node[right,draw, minimum width=0.15*\size,minimum height=0.8cm,fill=white](b0) {Control};
    \node[above=-0.2 of b0, minimum width=0.15*\size,minimum height=0.8cm] {1};
    \node[above left=-0.2 and -0.5 of b0, minimum width=0.2*\size,minimum height=0.8cm] {byte};

    \node[right=0cm of b0, draw, minimum width=0.2*\size,minimum height=0.8cm,fill=white](b1) {Longitud};
    \node[above=-0.2 of b1, minimum width=0.2*\size,minimum height=0.8cm] {1};      

    \node[right=0cm of b1, draw, minimum width=0.6*\size,minimum height=0.8cm,fill=white](b2) {Valor};
    \node[above=-0.2 of b2, minimum width=0.6*\size,minimum height=0.8cm] {8};      


    \node[below left=1 and -2 of b0 ,draw, minimum width=0.2*\size,minimum height=0.8cm,fill=white](h0) {Bloqueo};
    \node[below=-0.2 of h0, minimum width=0.15*\size,minimum height=0.8cm] {1};
    \node[below left=-0.2 and -0.5 of h0, minimum width=0.15*\size,minimum height=0.8cm] {bit};

    \node[right=0cm of h0, draw, minimum width=0.3*\size,minimum height=0.8cm,fill=white](h1) {M\'{a}ximo n$^o$ intentos};
    \node[below=-0.2 of h1, minimum width=0.2*\size,minimum height=0.8cm] {3};      

    \node[right=0cm of h1, draw, minimum width=0.2*\size,minimum height=0.8cm,fill=white](h2) {RSV};
    \node[below=-0.2 of h2, minimum width=0.2*\size,minimum height=0.8cm] {1};      

    \node[right=0cm of h2, draw, minimum width=0.4*\size,minimum height=0.8cm,fill=white](h3) {Intentos restantes};
    \node[below=-0.2 of h3, minimum width=0.4*\size,minimum height=0.8cm] {3};

正如所建议的，我认为matrix这是绘制字节和位字段的一个好选择。下一个代码显示如何使用两个矩阵，每个矩阵有两行，以及如何连接它们的角以表示第二个矩阵是详细字段。

\documentclass[tikz,border=2mm]{standalone}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[spanish]{babel}
\usepackage{lmodern}
\usepackage{textcomp}
\usetikzlibrary{matrix,positioning}

\begin{document}

%\begin{figure}    
\newcommand{\size}{\linewidth}

\begin{tikzpicture}[
    every path/.style={draw, font=\small},
     labelfield/.style={outer sep=0pt, minimum height=5mm,font=\small, anchor=center},
    field/.style={outer sep=0pt, draw, minimum height=8mm,
    minimum width=#1\size,font=\small,anchor=center}]

    \matrix (A) [matrix of nodes, column sep=-\pgflinewidth,
    row 1/.style={nodes=labelfield}, row 2/.style={nodes={field=.15}}] {
    byte & 1 & 1 & 8 \\
     &  Control & |[field=.2]|Longitud &  |[field=.6]| Valor\\
    };

    \matrix (B) [matrix of nodes, column sep=-\pgflinewidth, 
            below=5mm of A,
            row 2/.style={nodes=labelfield}, 
            row 1/.style={nodes={field=.15}}] {
     &  |[field=.2]| Bloqueo & |[field=.3]|Màximo n\textdegree{}  intentos &  |[field=.2]| RSV & |[field=.2]| Intentos restantes\\
    bit & 1 & 3 & 1 & 3\\
    };

    \draw (A-2-2.south west) -- (B-1-2.north west);
    \draw (A-2-2.south east) -- (B-1-5.north east);

\end{tikzpicture}
\end{document}
