我需要用 elsarticle 写一些东西并使用 endfloat，比如 1980 或类似的。
我还有一个附录。附录包含方程式、图形和表格。附录表格、图形、方程式应标记为附录 A 的图 A.1 ... 图 A.2。
elsarticle 的“endfloat”选项没有任何作用，因此我加载了该包。
** 更新 **
之前，所有图表的命名都与附录一致，而不是主文档。因此，我在附录之前保存计数器，并在文档结束之前恢复它。我还使用 \addtodelayedfloat 来调整编号。附录 C 有表格，标题为表格 C1。很棒。它也显示在表格列表中。很棒。但是，问题在于：
它说的是[表 2 关于这里]，而不是[表 1C 关于这里]。
不确定这里该做什么。下面是最小示例。

我自己解决了这个问题，方法是：
\let\thetableSAVED\thetable（最后恢复）\renewcommand\thepostfigure{A.\arabic{postfig}}\addtodelayedfloat{figure}{\renewcommand{\thefigure}{B\arabic{figure}}\setcounter{figure}{0}}
可能需要进行额外的计数器重置，具体取决于您所拥有的内容。
