我正在尝试制作一个长桌双栏文章，需要继续下一页单列方式。因此我使用长桌环境。由于桌子也比较宽，所以我需要让它景观. 而且它有较长的列标题，列宽适合列标题文本宽度，我试过这个（代码如下）。但我需要让它适合横向模式下的页面长度。现在我只能看到页面的一半。问题在于如何在 longtable、landscape 和 twocolumn 环境下将较长的列标题（列内容也很长）分成多行？
我还发现了一些包板状的。但我没有找到任何关于此内容的文档。关于此内容的链接也很有帮助（我从 leaf 上获取了一个模板，但对我不起作用。）。
请帮助我。提前致谢。

答案1
- 正如我在评论中提到的，
longtable它不适用于双列文档。若要在这样的文档中使用它，您需要将之前的文档更改longtable为一种column类型，之后将其返回为两列。这样，无论您使用什么afterpage，表格前后都会留有空白。 - 不清楚实际表格主体中的单元格内容是否比您的（虚拟）表格示例中显示的更长。如果不是，那么
p{...}最好使用列类型而不是列类型，例如l列
编辑：
- 通过
\multicolumn{1}{c}{....}在列标题中使用，您可以覆盖列规范。您应该删除它们的使用，并最终改为使用
\bfseries Study & \bfseries Approach & \bfseries Application No.
& \bfseries Concept Extraction or Concept Mapping model
& \bfseries Feature generation
& \bfseries Result
& \bfseries Input
& \bfseries Dataset \\ \hline
- 另一个解决方案是使用命令
thead{...}中的命令makcell并手动将列标题分成更多行，并在表格中使用例如l列类型。但是，如果单元格中的文本较长，并且您希望自动将其分成更多行，那么此解决方案将无法获得所需的结果
您的表格的可能解决方案之一是：
