从数据库1的分表同步到数据库2的总表，table:正则无法使用，只能用[0-9]是什么原因

"table": [ "user_[1-9]"]这种写法必须存在user_1、user_2。。。user_9这9张表
如果使用"table": [ "user_*"]，不起效
如果使用"table": [ "user_\\d"]，不起效
如果使用"table": [ "user_[\\d]"]，不起效
如果使用"table": [ "user_'\\d'"]，不起效

是不是不支持正则？
版本是2023.03

Start by tracing how the DataX table configuration interprets the reported patterns in version 2023.03. Compare the working `user_[1-9]` form with the non-working `user_*`, `user_\\d`, and related forms. Done means determining whether regular expressions are supported and documenting or correcting the observed behavior.
