 ##### Mapping Rows to a Java Bean
+
 Create a java bean and map its properties to the columns using the `@SheetColumn` annotation. The `@SheetColumn` annotation can be declared on the `Field`, as well as its `Accessor Methods`. Pick any one of them to configure the mapped `Column` as per convenience.
