我正在尝试在我的 tex 文档中创建一个表格，该表格或多或少类似于下图中的表格：
我找到了这段代码，但我仍然不知道如何分离图片中显示的每个表。

这可能是一个不受欢迎的观点，但在表格中使用交替颜色的最佳方式是不要使用它们。交替行颜色的趋势可以追溯到 Word，它曾一度将其用作默认格式。然而，这并不意味着这是好的做法。由于背景颜色的变化，字体和背景之间的对比度会降低，这实际上会使阅读更加困难。我建议改用干净、专业的设计：
\documentclass{article}
\usepackage{booktabs}
\begin{document}
\begin{tabular}{@{}lll@{}}
\toprule
Movies & Ratings & Tags\\
\midrule
ID & Movie ID & User ID\\
Title (Year) & User ID & Movie ID\\
Genre List & Rating & Tag\\
& Timestamp & Timestamp\\
\bottomrule
\end{tabular}
\end{document}
