You can not send html to another page (dialog). You should push only data, which will be used on another page.
To push data from datatable (which is considered to be a List) you should use #ManagedProperty annotation.
Assuming you have index page:
#ManagedBean(name="index")
#SessionScoped
public class IndexPage implements Serializable {
private List<String> values;
//getter and setter
}
and you have another page, where you would like to use that list:
#ManagedBean(name="nextPage")
#SessionScoped
public class AnotherPage implements Serializable {
#ManagedProperty(value="#{index.values}")
private List<String> forwardedList; //list with values form index page
//getter and setter
}

UPD: if you would like to forward a row, but not a list, you should just make minor change in AnotherPage class:
#ManagedBean(name="nextPage")
#SessionScoped
public class AnotherPage implements Serializable {
#ManagedProperty(value="{empresaBean.selectedEmpresa}")
private Empresa selectedValue; //value from selected row in your table
//getter and setter
}
