答案2
如果创建了一个包含大量垂直线和水平线的表格，其中一些应该是双线，那么很容易给人一种高安全性监狱的印象，因为这些讨厌的数字——读者的眼睛不敢进入这个监狱，以免永远被困在那里。我建议你通过省略所有垂直线并使用更少但间距更好的水平线来获得更“开放”的外观。这可以通过用包的线条绘制宏替换\hline和来实现。\clinebooktabs
我还想建议您使用siunitx包的机制 - 特别是它的S列类型 - 来排版数字；我会为标题材料提供一些更明确的结构，最后但并非最不重要的是，我会使用一个tabularx环境来允许根据需要自动换行，标题单元格中的材料。
以下是我提出的解决方案：
\documentclass{article} % or some other suitable document class
\usepackage{booktabs} % for \toprule, \midrule, \bottomrule etc macros
\usepackage{siunitx} % for 'S' column type
\newcolumntype{T}[1]{S[table-format=#1,
tight-spacing=true,exponent-product=\cdot,
round-mode=places,round-precision=4]}
\usepackage{tabularx,ragged2e}
\newcolumntype{C}{>{\Centering}X} % centered version of 'X' column type
\newcommand\mC[1]{\multicolumn{1}{C}{#1}} % handy shortcut macro
\usepackage{newtxtext,newtxmath} % optional
\usepackage{caption}
\captionsetup{skip=0.333\baselineskip,font=bf} % captions in bold
