Dropping a table or view does not delete the views, macros, or stored procedures that reference the dropped table or view. You need to drop referencing views, macros, and stored procedures explicitly.

Views, macros, and stored procedures fail after you drop a referenced table or view. If you replace a dropped table or view, the referencing views, macros, and stored procedures operate and provide the expected results only if the replacements have the same structure.

You cannot drop a table on which a trigger, hash index, or join index is defined. You must first drop the index, then drop the table definition.
