设置/添加子图计数器

Question

我需要更改第二个图和两个子图的计数器。对于图，它有效，但对于子图无效。非常感谢

\documentclass[]{article}
\usepackage{subcaption}


\begin{document}
    \begin{figure}[h]
        \caption{new}
    \end{figure}

    \begin{figure}[ht]
        \begin{subfigure}[t]{.45\linewidth}
            \caption{subfigure A}
        \end{subfigure}

        \begin{subfigure}[t]{.45\linewidth}
            \caption{subfigure B}
        \end{subfigure}     \caption{new}
    \end{figure}

    \addtocounter{figure}{-1}    %works
    \addtocounter{subfigure}{+2}         %doesnt work

    \begin{figure}[htb]
        \begin{subfigure}[t]{.45\linewidth}
            \caption{subfigure should be c instead of a, addtocounter for subfigure doesnt work}
        \end{subfigure}

        \begin{subfigure}[t]{.45\linewidth}
            \caption{subfigure should be d instead of b, addtocounter for subfigure doesnt work}
        \end{subfigure}
        \caption{number should like the figure before, addtocounter for figure works}
    \end{figure}
\end{document}

你需要把你的添加物放到subfigure柜台上里面第一个子图：

\documentclass[]{article}
\usepackage{subcaption}


\begin{document}
    \begin{figure}[h]
        \caption{new}
    \end{figure}

    \begin{figure}[ht]
        \begin{subfigure}[t]{.45\linewidth}
            \caption{subfigure A}
        \end{subfigure}

        \begin{subfigure}[t]{.45\linewidth}
            \caption{subfigure B}
        \end{subfigure}     \caption{new}
    \end{figure}
   \addtocounter{figure}{-1}    %works
   \addtocounter{subfigure}{2}  % doesn't work here
    \begin{figure}[htb]
           \begin{subfigure}[t]{.45\linewidth}
           \addtocounter{subfigure}{2} % works here
            \caption{ subfigure should be c instead of a, addtocounter for subfigure doesnt work}
        \end{subfigure}

        \begin{subfigure}[t]{.45\linewidth}
            \caption{subfigure should be d instead of b, addtocounter for subfigure doesnt work}
        \end{subfigure}
        \caption{number should like the figure before, addtocounter for figure works}
    \end{figure}
\end{document}
