如何将这 4 个迷你表格从垂直格式转换为 2 x 2 框架格式？

Question

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

Answer 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
