我正在尝试用 LaTex 制作一本 500 页的书，以生成 PDF 以供按需打印。大部分工作都正常。特别是，我希望章节位于右手边的页面上，如果前面有一个空白页，则空白页不应有页码。所有这些适用于 10 个章节和 4 个附录。
但在最后一个附录中，就在索引之前，我得到了一个空白的偶数页（第 466 页），正如预期的那样。然后奇数页（右手边的页面）有页码（467），但没有内容。该页的内容（附录标题和内容）出现在下一页（468）。然后是 469 上的索引。
附录的全部内容（一页）在一个物理页面上显示得很好，但是有一个“额外的”空白页正在插入。我正在使用 pdflatex，日志显示：
\output 处于活动状态时，发生 \vbox 未满（不良率 10000）[3] \output 处于活动状态时，发生 \vbox 过满（9.17294pt 太高）[4]
我认为这说明附录（表格）的内容有点太长了。事实上，如果我从表格中删除最后两行，一切都会按预期进行。
但一页上只有两行是不可取的，而且它确实都适合——只剩下这张我不需要的空白页了。
我可以理解如果 LaTeX 认为表格无法放在一页上，因此将其推到第二页，只留下附录标题，但它会将它们全部放在一起。
我在其他地方看到 LaTeX 似乎只是决定插入多余的垂直空白空间，但我可以使用 \vspace(-5mm) 左右来解决它们，但在这里我希望它“备份”整个页面，并且“在”触发移动到新页面的附录标题“之前”，所以我不知道如何解决这个问题。
我有一个我认为是最小工作示例的东西。出于某种原因，它似乎删除了额外空白页上的页码（示例中为第 3 页），但该页面仍在那里。

答案1
你收到警告
[1{/usr/local/texlive/2018/texmf-var/fonts/map/pdftex/updmap/pdftex.map}]
[2] (/usr/local/texlive/2018/texmf-dist/tex/latex/base/t1cmtt.fd)
Underfull \vbox (badness 10000) has occurred while \output is active [3]
Overfull \vbox (9.17294pt too high) has occurred while \output is active
[4]
这意味着页面已经满了（其实不是很多）。因为章节标题和后面的文本之间没有合法的分页点，但有一个前章节标题，TeX 将在那里中断并将材料移至下一页，但下一页会变得过满。
特别指定针对特殊情况的解决方案：添加负垂直空间。
实际情况可能需要不同的解决方法，例如将表分成两张。
一些注释。
9pt该课程没有选项book。- 没有必要，因为
\cleardoublepage之前\chapter已经处理好了。 - 加载包，而不是使用笨拙的代码来获取真正空白的页面
emptypage。
