This error could be due to several reasons but you are working with imported tables so try checking ENGINE and/or CHARSET parameters: It can happen you are trying to add a new table using a different one!

From: MySql - Using FOREIGN KEY Constraints

If you re-create a table that was dropped, it must have a definition that conforms to the foreign key constraints referencing it.

So if you are using a .sql file to import the customer's tables, open it and check it: at the end of queries there should be something like:

) ENGINE=InnoDB  DEFAULT CHARSET=latin1;

then be sure to use those same parameters for the new customer_entity table.

If the problem keep showing, check if foreign key column and the referencing have same column type or length, read more here.
