 SeaTunnel’s transform feature supports multi-table transformations, which is especially useful when the upstream plugin outputs multiple tables. This allows you to complete all necessary transformation operations within a single transform configuration. Currently, many connectors in SeaTunnel support multi-table outputs, such as `JDBCSource` and `MySQL-CDC`. All transforms can be configured for multi-table transform as described below.
 
+:::tip
+
+Multi-table Transform has no limitations on Transform capabilities; any Transform configuration can be used in a multi-table Transform. The purpose of multi-table Transform is to handle multiple tables in the data stream individually and merge the Transform configurations of multiple tables into one Transform for easier management.

 SeaTunnel transform支持多表转换，在上游插件输出多个表的时候特别有用，能够在一个transform中完成所有的转换操作。目前SeaTunnel很多Connectors支持多表输出，比如`JDBCSource`、`MySQL-CDC`
 等。所有的Transform都可以通过如下配置实现多表转换。
 
+:::tip
+
+多表Transform没有对Transform能力的限制，任何Transform的配置都可以在多表Transform中使用。多表Transform的作用针对数据流中的多个表进行单独的处理，并将多个表的Transform配置合并到一个Transform中，方便用户管理。
