我无法编写此表的乳胶代码。 我尝试了以下代码：
\begin{array}{ | l | l | l | l | l | l | l | }
\hline
\ & \ & \ & \ & \ & \ & \ \\ \hline
\ & \ & \ & \ & \ & \ & \ \\ \hline
\ & \ & \ & \ & \ & \ & \ \\ \hline
USA sample & & & Italian sample & & & \ \\ \hline
Sign & Capabilities & Magnitude & Sign & Capabilities & Magnitude & \ \\ \hline
Positive & Active Listening & 7.34 & Positive & Fluency of Ideas & 7.93 & \ \\ \hline
& Speech Recognition & 6.97 & & Operation Analysis & 2.46 & \ \\ \hline

\end{array}
但它并不正确，因为它没有像我希望的那样合并行。有人可以提供提示或建议吗？
答案1
只有一个版本（我的观点）如何使其成为适合文档的表格：
我已完成以下操作：
- 用
tabular代替array（这不是数学） - 使用
booktabs包，删除所有垂直规则和大多数水平规则 - 删除所有不必要的重复（包括多余的列和行）
- 通过将小数位数减少到 2 位来使用更统一的布局（
S可以设置列类型以执行自动舍入） - 将数字与小数点对齐
代码：

\usepackage{booktabs}
\usepackage{siunitx}
\usepackage[margin=1cm]{geometry}
