我们用\minisec{my fancy heading}它来生成章节或节内的多个中间标题。但这些小标题内通常也有浮动，有时会浮出标题。
对于部分（到段落），我们使用以下代码来防止对象在环境之外浮动。我的第一个想法是重复使用此代码，\minisec但它不起作用。我不确定这是否\minisec是一个真正的类似部分的环境，还是只是一个好看的中间标题。
有什么办法可以实现这个功能吗？对我来说，重新定义\minisec是最好的解决方案。
提前谢谢！

防止浮动元素超出文档区域的建议解决方案是使用包裹placeins：
\documentclass{scrreprt}
\usepackage{tabularx}
\usepackage{placeins}
\usepackage{mwe}
\begin{document}
\chapter{My Section}
\lipsum[1]
\minisec{Minisec 1}
\lipsum[1-2]
\begin{table}[htpb]
\caption{My table}
\begin{tabularx}{\columnwidth}{XXl}
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum
\end{tabularx}
\end{table}
\FloatBarrier
\minisec{Minisec 2}
Text text Text text Text text
\end{document}
您可以使用xpatch补丁\minisec总是以以下内容开头\FloatBarrier：
\documentclass{scrreprt}
\usepackage{tabularx}
\usepackage{placeins}
\usepackage{xpatch}
\xpretocmd{\minisec}{\FloatBarrier}{}{}
\usepackage{mwe}
\begin{document}
\chapter{My Section}
\lipsum[1]
\minisec{Minisec 1}
\lipsum[1-2]
\begin{table}[htpb]
\caption{My table}
\begin{tabularx}{\columnwidth}{XXl}
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum
\end{tabularx}
\end{table}
\minisec{Minisec 2}
Text text Text text Text text
\end{document}
如果您想使用内部placeins命令\@fb@secFB，您必须在修补之前使用以下命令加载placeins选项：section\minisec\AtBeginDocument
\documentclass{scrreprt}
\usepackage{tabularx}
\usepackage[section]{placeins}
\usepackage{xpatch}
\makeatletter
\AtBeginDocument{%
\xpretocmd{\minisec}{\@fb@secFB}{}{}%
}
\makeatother
\usepackage{mwe}
\begin{document}
\chapter{My Section}
\lipsum[1]
\minisec{Minisec 1}
\lipsum[1-2]
\begin{table}[htpb]
\caption{My table}
\begin{tabularx}{\columnwidth}{XXl}
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum\\
Lorem ipsum&Lorem ipsum dolor sit amet&Lorem ipsum
\end{tabularx}
\end{table}
\minisec{Minisec 2}
Text text Text text Text text
\end{document}
两个示例的结果都是：
