背景信息
我正在创建一本包含数千种食谱的书，采用双栏布局。配料表可以很短，但也可以很长，所以我喜欢将表格拆分。
问题
当某一列以章节/节/小节标题开始时，它会引发列中断，从而使页面的大部分区域保持空白。
我迄今为止尝试过
和往常一样，我尝试了不同的文档类别，例如 scrbook、article。我尝试使用不同的包及其各自的环境，例如 supertabular 和 xtab。Longtable 在两列布局中不起作用。我还尝试了不同的编译器，即 XeLaTeX（我常用的）和 pdfLaTeX。我还删除了所有样式、makros（为 mwe 再次添加了一些）和字体。到目前为止，没有任何效果。

答案1
所提供的示例并未产生所示的空间，但确实在节标题后显示了错误的分页符。
理想情况下，可以修改表格宏以不允许在该点进行分页，但更简单的方法是使用包 needspace来检查章节标题是否不会在页面上的位置太低。

\usepackage{xtab,needspace}
