答案1
wasysym
包包的\ocircle
寬度對我來說似乎是正確的:
\documentclass{book}
\usepackage{amsmath, amssymb}
\usepackage{wasysym}
\begin{document}
$\times$
$\otimes$
$\ocircle$
\end{document}
編輯:
如果您只需使用此符號作為表格中的一種複選標記,則可以使用\scalebox
載入graphicx
套件。
為了方便起見,我在這裡創建了三個巨集(\mytimes
、\myotimes
和\myocircle
):
\documentclass{book}
\usepackage{amsmath, amssymb}
\usepackage{wasysym}
\usepackage{graphicx}
\usepackage{array}
\usepackage{booktabs}
\newcommand{\mytimes}{\scalebox{4}{$\times$}}
\newcommand{\myotimes}{\scalebox{4}{$\otimes$}}
\newcommand{\myocircle}{\scalebox{4}{$\ocircle$}}
\begin{document}
\begin{tabular}{l>{\centering\arraybackslash}m{4em}}
\toprule
\multicolumn{2}{c}{Legend of symbols}\\
\midrule
Expected result & \myocircle \\
Calculated result & \mytimes \\
Expected result equal to calculated one & \myotimes \\
\bottomrule
\end{tabular}
\end{document}
