我已经为此奋斗了 30 分钟,但还是搞不清原因。这张长桌子的右边缘靠近顶部有一个缺口。我不知道为什么:

最后有一个?这里有一个 MWE 来重现它:这是一个小例子。表格本身延伸到很多页。

答案1
请参阅以下 mwe。我添加了缺失的部分&
,并添加了第二个没有垂直线的表格,我猜这个更好?
我添加了包geometry
以获得更小的边距,这样表格就不会与边距重叠。查看使用geometry
选项打印的打字区域和边距showframe
...

红线表示页面布局。如您所见,表格超出了文本边框。您可以通过两种方式消除这种情况:
- 增加文本宽度,例如使用
geometry
包(正如@Mensch 在他的回答中所建议的那样) - 相应地减少第三列的宽度
