\textit{p}-values for Granger causality tests for survey questions and returns. This table presents the \textit{p}-value for Granger causality tests for sentiment indicators and sector return indices using individual survey questions. The results cover the period from January 1985 to December 2014. \textit{r}, \textit{g-cause}, and \textit{sent} denote return, Granger-cause, and sentiment, respectively.

由于某些原因，标题没有扩展到最后一列，我找不到调整它的方法。

Answer 1

TeX 会准确地告诉你表格有多大

 Overfull \hbox (68.38016pt too wide) 

将您的专栏改为

\newcolumntype{L}{>{\raggedright\arraybackslash}m{1.5cm}}

使其适合，尽管它看起来仍然有点拥挤。也许重新措辞一些单元格标题会有所帮助，但这需要学科知识，所以我不建议在这里进行任何更改。

Answer 2

使用geometry环境sidewaystable和tabularx，您甚至可以使用\scriptsize：X单元格宽度约为 21 毫米。我借此机会对总体布局进行了一些改进：
