我快绝望了。我正在写一个带有对称选项的 tufte-book 类文档，偶数页上的所有图表和表格都居中，就像它们在奇数页上一样。标题始终显示在图像的右侧。
我尝试\forceversofloat在图形或表格环境中使用该命令，但是它不起作用：没有变化，浮点数总是设置在错误的位置。
这是我的代码：
\documentclass[a4paper,symmetric,openany,nobib]{tufte-book}
\usepackage[utf8]{inputenc}
\usepackage{geometry, sectsty, graphicx, array, changepage, marginfix, multirow, pgf-pie, amsmath, mathabx, xfrac, upgreek}
\usepackage{lipsum}
\geometry{top=22mm,bottom=18mm,right=27mm,left=20mm,marginparwidth=15mm,marginparsep=4mm}
\setlength{\headheight}{5.0pt}
\begin{document}
\chapter{One}
\lipsum[1]
Here is a floating element on an odd page, and all is fine.
\begin{table}[!htb]
\centering
\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|}
\hline
A&B&C&D&F&G&H&I&J&K&L&M&N&O&P&Q\\ \hline
1&2&3&4&5&6&7&8&9&10&11&12&13&14&15&16\\ \hline
\end{tabular}
\end{table}
\lipsum[1]
\newpage
\lipsum[1]
And here is a floating element on an even page, which is treated as if it were on an odd one.
\begin{table}[!htb]
\forceversofloat\centering
\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|}

A&B&C&D&F&G&H&I&J&K&L&M&N&O&P&Q\\ \hline

\end{tabular}
\end{table}
\lipsum[1]
\end{document}
这就是我得到的：
答案1
tufte 类定义一个跨越文本区域和侧边距区域的浮动环境，用于将标题放置在边距空间中。
它将生成表格或图形及其标题。在您的示例中，缺少标题，这导致错位。
您可以通过添加标题或（如果没有必要）使用居中表格形式来改善结果。
（1）添加标题
