Review Comment:
   ```java
     /**
      * A name to identify this table. Implementations should provide a 
meaningful name, like the
      * database and table name from catalog, or the location of files for this 
table.
      */
   ```
   
   Check the comments above from the spark codebase, the cases below seem not 
to be handled,
   
   1. the location of files for this table
   2. when the catalog name is absent
   3. backtick-quoted name parts, such as cat1.db.\`abc.xyz\`
