If you are not seeing Top Line Filter for af:table

Though you have set sortable=true and filterable =true to your <af::table> component, sometimes you may still not find top line filters for <af:table> columns.

Below are the points, you may have to validate.

1.Define searchRegion in respective Page Definition


<searchRegion Binds="EmpViewIterator" Criteria=""
                  Customizer="oracle.jbo.uicli.binding.JUSearchBindingCustomizer"
                  id="EmpViewQuery"/>

2. Make sure <af:table> component should have below two attributes


       filterModel="#{bindings.EmpViewQuery.queryDescriptor}"
       queryListener="#{bindings.EmpViewQuery.processQuery}"
