像这样。我想压缩它的尺寸以适合列的一侧。两个表重叠了。那么我该怎么做呢？请帮助我。
答案1
您有两个选择：要么减少所有值的小数位数以减小表格宽度，要么旋转表格环境。对于前者，我siunitx仅应用了 3 个有效数字，标记后至少有一位小数.。如果您需要有效数字，您可以应用sidewaystable，而不是常规table旋转 who 环境；sidewaystable在包中定义rotating。另一个选项是在（或）landscape中定义的环境。lscapepdflscape
确保两个表格之间至少保留一个空白区域以强制换行，这样表格就可以相互叠放在一起。
这是使用的示例siunitx。

编辑。
建议表格中的表格无法容纳一列。为此，您需要将它们分成两半并应用进一步的格式。由于标题会重复，因此可以将其移至顶部。我通常不赞成使用垂直线，但我觉得在这种情况下一行可能会有所帮助。
我意识到r先水平排序，然后垂直排序。在这种情况下，分隔条可能不太合适；这必须由您决定。
