     Hi @strongduanmu 
   
     I would like to work on this issue. I've already implemented a solution for supporting
     `ALTER TABLE ... RENAME TO` and `RENAME TABLE` statements for sharding and broadcast
     tables.
   
     ### Implementation Summary:
     - Removed restrictions in `ShardingAlterTableSupportedChecker` and
     `ShardingRenameTableSupportedChecker`
     - Added validation to prevent table name conflicts
     - Updated metadata refreshers to handle rename operations
     - Added comprehensive unit tests (8 tests, all passing)
   
     The physical table renaming works for both single and sharding/broadcast tables. For
     sharding/broadcast tables, the rules can be updated manually via DistSQL (consistent with
      existing DROP/CREATE TABLE behavior).
   
     I'm preparing to submit a PR. Any feedback or guidance would be appreciated!
   
     Thanks!
