两个并排的表格，带有独立和全局标题

Question

我想在我的文档中并排放置两个表格，并为它们添加 (a) 和 (b) 子标题，以及一个全局标题“表格 1. Blahblahblah”（仅跨越其中一列）。目前，我只能将表格与独立的标题一起放置（如下图所示）。我尝试了 subcaption 包和 subtable，但它声称 subtable 环境未定义。我也尝试了 subfigure 包，但它与 subfig 包冲突。

我目前得到的是：

我想要下面这样的内容，但添加（a）和（b）子标题：

谢谢

Answer 1

它适用于subcaption：

或使用floatrow（这样可以轻松添加侧边字幕）：

我猜你想让子表的行显示在两列中。以下是我针对该floatrow版本注释的代码：
