我已经使用下表生成器站点来创建下表，但感觉它比需要的稍微复杂一些，而且我无法让颜色单元格工作。https://www.tablesgenerator.com/
代码有什么问题？我是否拥有所有必需的软件包？
我还想了解 \multicolumn 到底是怎么回事，这有必要吗？

答案1
除了表格中一个单元格的颜色问题之外，您的文档示例还存在许多其他问题：
- 您应该意识到，加载许多包，
beamer如xcolor，，，...amsmathgraphicxhyperref - 这些包的选项可以写成 `beamer 的选项。在你的情况下，你应该写
\documentclass[xcolor={table}]{beamer}
而不是\documentclass{beamer}，您的问题就会消失。
- 有些包需要加载两次。删除所有重复的包！
- 乍一看，使用表格生成器似乎是一种方便的解决方案，但结果代码却非常混乱
- 缩放表格，使其适合框架不是一个好主意，最好重新设计一下表格。尝试在列标题中写入长文本，并在两行中选择较小的字体（例如
\scriptsize）。 - 对于最后一列，我将使用
S“siunitx 包”中定义的列类型。 - 使用的标准
beamercm（计算机现代）字体没有斜体粗体版本。对于它们，您应该加载lmodern或newtxtext, newtxmath或...
除了上述内容之外，您还可以考虑使用tabularray带有库的包varwidth作为siunitx您的表。使用它，您的 MWE 可以是：
\documentclass[xcolor={table}]{beamer}
\usepackage{mathtools}
\usepackage{newtxtext, newtxmath}
%\usepackage{lmodern} % <--- alternative to standard cm fonts
\usepackage{tabularray}
\UseTblrLibrary{varwidth, siunitx}

答案2
我需要包含一个缺少的包裹。
\usepackage{colortbl}
这修复了我的错误。
