我设法将问题归结为这个最小的例子。
\documentclass{book}
\usepackage{graphicx}
\usepackage{xltabular}
\usepackage{placeins}
\usepackage[showframe]{geometry}
\begin{document}
\chapter{Everything}
\begin{figure}[h]
\includegraphics[height=5cm]{example-image-a}
\end{figure}
\FloatBarrier
\begin{table}
\begin{tabular}[h]{|l|l|l|}
\hline
test & test & test \\ \hline
test & test & test \\ \hline
test & test & test \\ \hline
\end{tabular}
\end{table}
\FloatBarrier
\begin{figure}[h]
\includegraphics[height=5cm]{example-image-a}
\end{figure}
\FloatBarrier
\begin{xltabular}{\textwidth}{ |X|l| }
\hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
test & test \\ \hline
\end{xltabular}
\FloatBarrier
\begin{figure}[h]
\includegraphics[height=7cm]{example-image-a}
\end{figure}
\FloatBarrier
\begin{xltabular}{\textwidth}{ |X|l|l|l| }
\hline
test & test & test & test \\ \hline
test & test & test & test \\ \hline
test & test & test & test \\ \hline
test & test & test & test \\ \hline
test & test & test & test \\ \hline
test & test & test & test \\ \hline
test & test & test & test \\ \hline
test & test & test & test \\ \hline
test & test & test & test \\ \hline
test & test & test & test \\ \hline
test & test & test & test \\ \hline
test & test & test & test \\ \hline
test & test & test & test \\ \hline
test & test & test & test \\ \hline
\end{xltabular}
\FloatBarrier
\begin{figure}[h]
\includegraphics[height=9cm]{example-image-a}
\end{figure}
\FloatBarrier
\end{document}
结果：
如您所见，最后一个图形部分超出了页面范围。它应该在下一页。我在文档中的多个地方都遇到了这个问题。如果[h]图形上没有使用该选项，一切似乎都很好。
