任务和 align* 环境基线对齐

Question

在下面的例子中，我想在环境中提出方程式align*，这样它们就会与包的编号标签位于同一行Tasks。我该怎么做？

\documentclass[12pt,fleqn]{exam}
\usepackage[a4paper, total={180mm,247mm},left=15mm,top=20mm]{geometry}
\usepackage{amsmath,tasks}
\newcommand\dotfillin[1][4cm]{\makebox[#1]{\dotfill}}
\settasks{label=(\alph*),label-width=18pt,label-align=right,item-indent=23pt,label-offset=7pt}
\begin{document}
    \begin{tasks}(2)
    \task 
        \begin{align*}
            307 \times 8 & =\dotfillin[3cm]\\
                         & =\dotfillin[3cm]\\
                         & =\dotfillin[3cm]\\
                         & =\dotfillin[3cm]\\
        \end{align*}
    \task
        \begin{align*}
            208 \times 99 & =\dotfillin[3cm]\\
                          & =\dotfillin[3cm]\\
                          & =\dotfillin[3cm]\\
                          & =\dotfillin[3cm]\\
        \end{align*}
    \end{tasks}
\end{document}

Answer 1

{align*}您可以通过用环境替换环境来实现格式化目标{aligned}[t]。只需确保将aligned环境置于内联数学模式即可。

\documentclass[12pt,fleqn]{exam}
\usepackage[a4paper, total={180mm,247mm},left=15mm,top=20mm]{geometry}
\usepackage{amsmath,tasks}
\newcommand\dotfillin[1][3cm]{\makebox[#1]{\dotfill}}
\settasks{label=(\alph*), label-width=18pt, label-align=right,
          item-indent=23pt, label-offset=7pt}

\begin{document}
\begin{tasks}(2)
\task 
\quad$\begin{aligned}[t]
            307 \times 8 &= \dotfillin \\
                         &= \dotfillin \\
                         &= \dotfillin \\
                         &= \dotfillin 
      \end{aligned}$
\task
\quad$\begin{aligned}[t]
            208 \times 99 &= \dotfillin \\
                          &= \dotfillin \\
                          &= \dotfillin \\
                          &= \dotfillin 
      \end{aligned}$
\end{tasks}
\end{document}
