如何用乳膠得到盒子的角？

Question

我創建了一個表格，必須在其中放置此框，不知道如何使此框準確顯示在圖像中。

Answer 1

這非常容易tcolorbox。

下次詢問時，請加入最小工作範例（MWE）。

\documentclass{book}
\usepackage[most]{tcolorbox}
\newtcolorbox{mybox}[1][]{%
  enhanced,
  opacityback=0, 
  frame hidden,% from https://tex.stackexchange.com/a/247509/101651
  % from https://tex.stackexchange.com/a/431760/101651:
  overlay unbroken and first ={%
    \draw[thick] ([xshift=10pt]frame.north west) -| ([yshift=-10pt]frame.north west);
    \draw[thick] ([xshift=10pt]frame.south west) -| ([yshift=10pt]frame.south west);
    \draw[thick] ([xshift=-10pt]frame.north east) -| ([yshift=-10pt]frame.north east);
    \draw[thick] ([xshift=-10pt]frame.south east) -| ([yshift=10pt]frame.south east);
  }
}
\begin{document}
\begin{mybox}
   Something:
