TikZ 文本周围的圆形/椭圆形，第 2 部分 - ExSheets 间距

Question

这是第 1 部分 TikZ 文本周围的圆形/椭圆形。

我的新问题：自从将上一个帖子中的答案与 ExSheets 结合起来后，正确答案周围出现了额外的空格。为什么？

\documentclass[a4paper]{article}

\usepackage{tabularx}

\usepackage{exsheets}
\SetupExSheets{solution/print=true}

\usepackage{amssymb}

\newcolumntype{C}[1]{>{\centering\arraybackslash}m{#1}}

\usepackage{tikz}

\newcommand\circleanswer[1]
{
 \PrintSolutionsTF
  {
   \begin{tikzpicture}[baseline=(word.base)]
    \node[inner sep=0pt]  (word) {#1};
    \begin{pgfinterruptboundingbox}
    \node[draw,color=red] at (word) {\phantom{#1}};
    \end{pgfinterruptboundingbox}
   \end{tikzpicture}
  }
  {#1}
}

\begin{document}

Proper fractions live on the \circleanswer{LEFT}/RIGHT side of zero.

\end{document}

Answer 1

您在命令定义中添加了几个显式空格。新行是一个空格。因此，命令中的每个新行都呈现为空格。解决方案很简单，就是不插入空格。

\documentclass[a4paper]{article}
\usepackage{tabularx}
\usepackage{exsheets}
\SetupExSheets{solution/print=true}
\usepackage{amssymb}
\newcolumntype{C}[1]{>{\centering\arraybackslash}m{#1}}
\usepackage{tikz}

\newcommand\circleanswer[1]
{%
 \PrintSolutionsTF
  {%
   \begin{tikzpicture}[baseline=(word.base)]
    \node[inner sep=0pt]  (word) {#1};
    \begin{pgfinterruptboundingbox}
    \node[draw,color=red] at (word) {\phantom{#1}};
    \end{pgfinterruptboundingbox}
   \end{tikzpicture}%
  }%
  {#1}%
}

\begin{document}
