我正在尝试longtable在横向模式下制作页面宽度为 的表格。为了更容易设置列宽，我定义了一种新的列类型，即 [p] 列，但大小是 的一小部分\linewidth。但是当我编译时，表格会超出文档标题。

\caption{Table caption is also not very small and it seems to be places wrongly as well, like it is centered with the table that goes over the header here it is the linewidth which seems to be correct \the\linewidth} \label{table:articles} \\\toprule

Some author name here 1 & Something goes here and it is quite big, it fills several lines in the table describing boring stuff & The sizes vary for each column, sometimes there is more boring stuff and others & Some are usually short & So the column width is set to more or less fit these differences & I describe some aspects of scientific articles & I dont understand why this doesnt work for me & It goes on for a few pages but here I added just two lines \\

\tabcolsep在新的列类型定义中考虑值：使用此代码
\newcolumntype{L}[1]{>{\raggedright\let\newline\\\arraybackslash}p{\dimexpr#1\linewidth-2\tabcolsep\relax}}
同样，对于R和C，问题也解决了。或者，您可以使用 包，它将的ltablex功能引入。longtabletabularx
