我们如何才能在 baposter 中为子图添加子标题。文件 baposter.cls 可在此处获取baposter.cls.代码如下：

答案1
每个posterbox都是一个盒子。您不能将诸如figure和 之类的浮动环境table放入盒子中。
解决方案是使用包中的创建一个假figure环境。请注意，您需要在前言中更改为。然后按预期工作。您可以恢复使用而不是，尽管当然仍然有效。\setcaptiontype{figure}subcaption\usepackage{caption}usepackage{subcaption}Subfloat\caption\captionof{figure}\captionof{figure}
另一个选项是使用\subcaptionbox，同样来自subcaption包，用于添加子标题。语法为：\subcaptionbox[<list entry>]{<heading>}[<width>][<inner-pos>]{<contents>}。示例仅使用{<heading>}，设置为figure，和{<contents>}，设置为Sub1或Sub2。\subcaptionbox此处未使用这些选项，但它们确实提供了额外的定位精度。请参阅subcaption文档以了解更多详细信息。
