如何在考试类别的表格中嵌入 \choices？

Question

类似问题：以表格形式呈现的考试类别多项选择题答案，我试图将其嵌入\choices到表格格式中并看起来像一张表格。

\documentclass[11pt]{exam}
\usepackage{mathtools}
\usepackage{xspace}
\usepackage{array}
\usepackage{tikz}
\printanswers
\newcommand{\wideunderline}[2][2em]{%
  \underline{\makebox[\ifdim\width>#1\width\else#1\fi][c]{#2}}%
}
\begin{document}

\fbox{\parbox{\linewidth}{
When compared to the graph of $y=f(x)$, the graph of $8y=f(-x)$ has been reflected in the \wideunderline[1.5cm]{\textit{i}} and vertically stretched about the x-axis by a factor of \wideunderline[1.5cm]{\textit{ii}}}}\medskip
\begin{questions}
\question The statement above is completed by the information in row:\medskip

\begin{choices}
\renewcommand\arraystretch{1.5}
\choice A
\correctchoice B
\choice C
\choice D
\end{choices}

\question I want choice B embedded in the table. 
%\begin{choices}%%%is this possible?
\begin{tabular}{|c|c|c|}
\hline
    \textbf{Row }& \textbf{\textit{i}}&\textbf{\textit{ii}}\\
    \hline
    A &  $y$-axis&8\\ 
    \hline
        B &  $y$-axis&$\frac{1}{8}$\\%I would like the choice to be embeded i.e. \choice B is in the first column of the table in row 3.
    \hline
        C &  $x$-axis&8\\
    \hline
        D &  $x$-axis&$\frac{1}{8}$\\
    \hline
\end{tabular}
%\end{choices}%%%%doesn't work. 
\end{questions}
\end{document}

谁能帮我这个？

环境oneparchoices​几乎它可以实现您想要的功能，但是它有两个主要限制：首先，将选项嵌入到表格中会使处理变得混乱；\correctchoice其次，格式会自动在\choice第一个选项之后的每个选项前添加额外的空格，这在段落情况下是有意义的，但在其他情况下则不然。

为了获得接近您想要的结果，我修改了环境oneparchoices以删除水平间距，并且仅将正确的选择格式应用于标签而不是整个答案（考虑到我们将命令放入表格\choice的单元格中，以可推广的方式执行此操作将具有挑战性。

这是新的环境定义：

\makeatletter
\newenvironment{noparchoices}%
  {%
    \setcounter{choice}{0}%
    \def\choice{%
      \refstepcounter{choice}%
      \choicelabel
      % No need to put the following into a token string; we just put
      % the choicelabel onto the page, so we're at the spot whose page
      % number we want to record:
      \questionobject@pluspagecheck
    }% choice
    \def\CorrectChoice{%
      \refstepcounter{choice}%
      \ifprintanswers
        \begingroup 
        \CorrectChoice@Emphasis
      \fi
      \choicelabel
      \endgroup
      % No need to put the following into a token string; we just put
      % the choicelabel onto the page, so we're at the spot whose page
      % number we want to record:
      \questionobject@pluspagecheck
    }% CorrectChoice
    \let\correctchoice\CorrectChoice
    % If we're continuing the paragraph containing the question,
    % then leave a bit of space before the first choice:
    \ignorespaces
  }%
  {}
\makeatother

下面是它的使用示例：

\begin{noparchoices}
\begin{tabular}{|c|c|c|}
\hline
    \textbf{Row }& \textbf{\textit{i}}&\textbf{\textit{ii}}\\
    \hline
    \choice &  $y$-axis&8\\ 
    \hline
        \correctchoice &  $y$-axis&$\frac{1}{8}$\\
    \hline
        \choice &  $x$-axis&8\\
    \hline
        \choice &  $x$-axis&$\frac{1}{8}$\\
    \hline
\end{tabular}
\end{noparchoices}
