我喜欢将以下四个表格转换为 2 x2 格式，而不是垂直显示它们。另外，图形环境将它们标记为图，这并不理想，因为我想将它们标记为表格。请帮忙。

期望的输出类似于
答案1
像这样吗？
相对于 OP 的示例代码，一些主要的变化如下：
- 将的所有四个实例更改
subfigure为subtable并将 的实例更改figure为table - 将全部四个实例更改
{\textwidth}为{0.475\textwidth} - 在标题单元格中使用缩写（以使列变窄）
- 减少值
\tabcolsep（影响空白填充的数量） - 切换到
\small相对字体大小（字体大小线性减少 10%） - 消除子表 a/b 和 c/d 之间的空行，因为空行会导致换行
\vspace{1em}子表 a/b 和 c/d 之间的变更\hfill
