\insertTableNotes 干扰标题后的间距

Question

我遇到一个问题，即表格标题和下一个元素（例如新章节标题）之间的间距并不直接取决于标题本身的位置。如果我在标题前添加，这个空间似乎会从原始边距中“减去”。在下面的例子中，和和下一个小节\insertTableNotes之间的间距并不相同。原因是什么？Table 1Table 2

\documentclass[a4paper]{article}

    bottom=25mm,
    foot=8mm

我仍然找不到解决方案，有人遇到过类似的问题吗？

Answer 1

\begin{center}当环境被常规布局命令替换时，情况会好得多\centering。事实上，表格 1 之后的间距是不正确的。
