Additionally...

If you had innodb_file_per_table = OFF when you CREATEd the TABLE, then the data (and indexes) is in the file ibdata1 .
If you had innodb_file_per_table = ON when you CREATEd the TABLE, then the data (and indexes) is in the file tablename.ibd .

In the latter case, the size of the .ibd file is how much space the table is consuming on disk. It is likely to be bigger than Data_length + Index_length because of Data_free. This last value is yet another "overhead" that InnoDB imposes on us -- for performance reasons.
