工作台居中/对齐

工作台居中/对齐

有人能帮我居中吗？我本质上想让图案和表格中的文本居中。我会添加更多图案，也会调整图案大小。

我\tabularx专门使用它，因为我知道如何合并表格的第一行。如果有更好的方法可以使用，我很乐意妥协。虽然尽可能简单的东西会很棒！

提前致谢。 在此处输入图片描述

从第一张截图可以看出，mleandriis 提出的列确实运行良好。

\documentclass{article}

\usepackage{tabularx}
\usepackage{array}
\usepackage{graphicx}

\usepackage{tikz}

\usetikzlibrary{patterns}
\usetikzlibrary{patterns.meta}

\renewcommand\tabularxcolumn[1]{m{#1}}

\begin{document}

\begin{tabularx}{0.7\textwidth}{|*{3}{>{\centering\arraybackslash}X|}}
    \hline
    \multicolumn{3}{|c|}{Diagram Key}\\
    \hline
    Pattern
        & Pattern Description 
        & Area Type\\
    \hline
    \begin{tikzpicture}
        \draw [
            draw=red,
            pattern={Lines[angle=45,distance=4pt]},
            pattern color=red
        ] (0,0)--(0,1)--(1,1)--(1,0)--cycle;
    \end{tikzpicture}  
        & 1 
        & Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua\\

要修复间距问题，您可以将基线设置tikzpicture为大于您看到的空白的任意值。0.5em例如：

\documentclass{article}

\usepackage{tabularx}
\usepackage{array}
\usepackage{graphicx}

\usepackage{tikz}

\usetikzlibrary{patterns}
\usetikzlibrary{patterns.meta}

\renewcommand\tabularxcolumn[1]{m{#1}}

\begin{document}

\begin{tabularx}{0.7\textwidth}{|*{3}{>{\centering\arraybackslash}X|}}
    \hline
    \multicolumn{3}{|c|}{Diagram Key}\\
    \hline
    Pattern
        & Pattern Description 
        & Area Type\\
    \hline
    \begin{tikzpicture}[baseline=.5em]
        \draw [
            draw=red,
            pattern={Lines[angle=45,distance=4pt]},
            pattern color=red
        ] (0,0) rectangle (1,1);
    \end{tikzpicture}  
        & 1 
        & 1\\
    \hline
    $a$      
        & 2  
        & 7\\
    \hline
    $b$      
        & 2 
        & 7\\
    \hline
    $c$      
        & 6 
        & 7\\
    \hline
\end{tabularx}  

\end{document}

编辑

OP 希望矩形前后有相等的空白。这可以通过在环境\vspace{.5em}之前和之后添加来轻松实现tikzpicture。为了获得更模块化的代码，您可以\vspace{.5em}使用etoolbox's\BeforeBeginEnvironment和AfterEndEnvironment命令将 添加到开始和结束文档挂钩中。理想情况下，您也只会在环境内部调用它，tabularx以确保任何tikzpicture表格外部的内容都不会受到此新间距的影响。

在第一个实现中可能会添加一些垂直间距，但你真正应该考虑第二个实现。

居中 atikzpicture实际上很容易。

\documentclass{article}
\usepackage[hmargin = 1.25 in, bmargin=.8 in, tmargin=1.2in, headsep=0.2in]{geometry}
\usepackage{booktabs}
\usepackage{tabularx}
\usepackage{tikz}
\usetikzlibrary{patterns}
\usetikzlibrary{patterns.meta}

\begin{document}


\begin{tabularx}{0.7\textwidth}{| *{3}{>{\centering\arraybackslash}X|}}
\hline
\multicolumn{3}{|c|}{Diagram Key} \\
\hline
Pattern  & Pattern Description & Area Type \\
\hline
\begin{tikzpicture}[baseline=(current bounding box.west)]
  \draw [draw=red, pattern={Lines[angle=45,distance=4pt]},pattern color=red]
    (0,0)--(0,1)--(1,1)--(1,0)--cycle;
\end{tikzpicture}
    & $1$ & 7  \\
\hline
$a$ & $2$ & 7 \\
\hline
$b$ & $2$ & 7  \\
\hline
$c$ & $6$ & 7  \\
\hline
\end{tabularx}

\bigskip

\begin{tabular*}{0.7\textwidth}{@{\extracolsep{\fill}}ccc@{}}
\toprule
\multicolumn{3}{c}{Diagram Key} \\
\midrule
Pattern  & Pattern Description & Area Type \\
\midrule
\begin{tikzpicture}[baseline=(current bounding box.west)]
  \draw [draw=red, pattern={Lines[angle=45,distance=4pt]},pattern color=red]
    (0,0)--(0,1)--(1,1)--(1,0)--cycle;
  \end{tikzpicture}
    & $1$ & 7  \\
$a$ & $2$ & 7 \\
$b$ & $2$ & 7  \\
$c$ & $6$ & 7  \\
\bottomrule
\end{tabular*}

答案3

\renewcommand\tabularxcolumn[1]{m{#1}} 根据和，我建议如下cellspace：

在此处输入图片描述

\documentclass{article}
\usepackage[hmargin = 1.25 in, bmargin=.8 in, tmargin=1.2in, headsep=0.2in]{geometry}
\usepackage{booktabs}
\usepackage{tabularx}
\usepackage{tikz}
\usetikzlibrary{patterns}
\usetikzlibrary{patterns.meta}

\usepackage[column=0]{cellspace}
\setlength{\cellspacetoplimit}{0.5\tabcolsep}
\setlength{\cellspacebottomlimit}{\cellspacetoplimit}
\addparagraphcolumntypes{X}
\renewcommand\tabularxcolumn[1]{m{#1}}

\begin{document}

\begin{tabularx}{0.7\textwidth}{| *{3}{>{\centering\arraybackslash}0{X}|}}
\hline
\multicolumn{3}{|0c|}{Diagram Key} \\
\hline
Pattern  & Pattern Description & Area Type \\
\hline
\begin{tikzpicture}
  \draw [draw=red, pattern={Lines[angle=45,distance=4pt]},pattern color=red]
    (0,0)--(0,1)--(1,1)--(1,0)--cycle;
\end{tikzpicture}
    & $1$ & 7  \\
\hline
$a$ & $2$ & 7 \\
\hline
$b$ & $2$ & 7  \\
\hline
$c$ & $6$ & 7  \\
\hline
\end{tabularx}
\end{document}
