\FBwidth 声明似乎仅当子图放在同一行时才适用于子图和父图。
当子图位于单独的行时，图形标题的 \FBwidth 不会测量最大子图的宽度，而是测量所有子图宽度的总和。
有没有办法将换行应用到图形的标题上？
\documentclass{article}
\usepackage{subfig}
\usepackage{floatrow}
\usepackage[top=1cm,bottom=1cm,left=1cm, right=1cm]{geometry}
% For demo only
\usepackage[demo]{graphicx}

In the following example, subfigures' captions are wraped to the size of each subfigure. Global caption is wraped to the size of both figures.
\begin{figure}[h]
\centering
\ffigbox[\FBwidth]{
\begin{subfloatrow}[2]
\ffigbox[\FBwidth]{
\caption{A very very very very very very very very
very very very very long subcaption}
}
{
\includegraphics[width=4cm,height=4cm]{image1}
}
\ffigbox[\FBwidth]{
\caption{A very very very very very very very very
very very very very long subcaption that is even
longer than the first}
}
{
\includegraphics[width=4cm,height=3cm]{image1}
}
\end{subfloatrow}
}
{
\caption{And here's the caption to the main figure that
seems to be working ok}
\label{tournaments}
}
\end{figure}
Unfortunately, if subfigures are place on separate rows, the global caption wraps as if they were in the same row.
\begin{figure}[h]
\centering
\ffigbox[\FBwidth]{
\begin{subfloatrow}[1]
\ffigbox[\FBwidth]{
\caption{A very very very very very very very very
very very very very long subcaption}
}
{
\includegraphics[width=4cm,height=3cm]{image1}
}
\end{subfloatrow}
\begin{subfloatrow}[1]
\ffigbox[\FBwidth]{
\caption{A very very very very very very very very
very very very very long subcaption that is even
longer than the first}
}
{
\includegraphics[width=4cm,height=3cm]{image1}
}
\end{subfloatrow}
}
{
\caption{And here's the caption to the main figure that
seems to be working ok}
\label{tournaments}
}
\end{figure}
\end{document}

使用包做同样的事情应该容易得多。但是，您可以在环境中subfig手动调整标题的宽度。\captionsetup{width=0.3\textwidth}figure
