我也构建了一个表格，但第二个表格没有出现。这是输出： https://i.stack.imgur.com/crapl.jpg 以下是表格：

答案1
您可能对以下内容更满意：
tabularx我对表格的两个部分都使用了单一环境。这可确保表格的宽度仅与当前文本宽度（或您指定的任何其他宽度）一样宽。我还对\multicolumn{2}{l}{...}“标题”使用了单一环境。这可确保左列与内容一样宽，而不考虑标题文本的宽度。因此，列之间未使用的空白空间会减少。我还用包\addlinespace中的命令替换了空booktabs行。垂直空白比空行略小，但仍在行之间提供足够的视觉分隔。最后，我还添加了一个更简单的表格线条着色变体。取消下面代码中的三行注释，表格将呈现灰色线条而不是黑色线条。

答案2
如果您确实希望两个子表中的第一列宽度不同...
这是您作为 MWE 的表格，但很难理解您想要实现什么。如您所见，两个嵌套表格进入主表格的第一列，在第二个嵌套表格中，您定义了三列，但使用了两列。
子表格比文档边距宽。可以通过减小边距来解决此问题，只需添加
\usepackage[left=2.5cm, right=2.5cm]{geometry}
到 MWE 的序言。最后一个单元格中定义的命令似乎是尝试使用灰色规则。相反，使用
\arrayrulecolor{gray!50}
为了避免过满hboxes和复杂的列计算，我将主表转换为 tabularx-table 并将第二列设为 X 列。
