我怎样才能在乳胶中绘制长表？

您好，我想在两页乳胶中绘制长表。我使用了 longtable 包，但所有内容仍然相互重叠。它看起来像图片中的那样。我的代码如下：

\usepackage{longtable}
\begin{document}
    \begin{longtable}[H]

  • 你的表格是否超过一页？如果不是，你可以使用可以插入浮动元素的xltabular表格环境来代替。tabularxtable
  • longtable在上面使用了MWE 来代替xltabular（它是longtable和tabularx表环境的组合）。
  • 对于水平规则，使用makecell包中定义的规则
  • 使用包S中定义的列类型将数字按小数点对齐siunitx
  • 我想知道您是否真的需要 9 位小数？

在此处输入图片描述

编辑： 如果你不喜欢小数点对齐的数字，那么可以替换

    \begin{xltabular}{\linewidth}{ |l||S|S|S| }

和

    \begin{xltabular}{\linewidth}{ |l||*{3}{>{\hskip 3em}X|} }

你将获得：

答案2

通过以下重新设计，避免使用垂直线，只使用一些水平线和均匀分布的白色间隙作为引导眼睛的视线，您的表格可以轻松地放在一页上：
