如何将两个 PgfplotsTable 对象与图形对齐？

这是对精彩问答的后续这里。我为此苦苦挣扎了很久，非常感谢您的帮助。假设我有两个相关但规模不同的数据集。为它们制作两个表格是不合理的，但将数据集放在同一个置信区间图中也是行不通的。理想的解决方案是将数据显示在一个表格中，并带有如下子标题：
在此处输入图片描述

然而，我在尝试对齐这些表格时遇到了麻烦。理想的做法是让它们dec sep align对齐，但使用我目前基于以下方法无法做到这一点这个问题。我认为我可以通过直接将数据输入tabular环境来获得更好的结果，但这样我就会失去@Jake 的天才动态解决方案。有人知道如何让这些表格统一或对齐，以便它们看起来漂亮且足够专业，适合科学出版物吗？

这是我用来生成上表的修改后的代码：

在这种情况下，我建议使用包S提供的列类型siunitx来处理对齐。您可以通过将列类型设置为来指定对齐的数字格式S[table-format=-2.2]，这指示siunitx假设列中的数字有一个符号，并且在小数点符号前后各有两位数字：
