You need to Implement the OnCellAction event.follow these steps;
1. Goto WDDOMODIFYVIEW and place the following code
IF first_time IS INITIAL.
    DATA lo_cmp_usage TYPE REF TO if_wd_component_usage.
    lo_cmp_usage =   wd_this->wd_cpuse_usg_alv( ).
    IF lo_cmp_usage->has_active_component( ) IS INITIAL.
      lo_cmp_usage->create_component( ).
    ENDIF.
    DATA lo_interfacecontroller TYPE REF TO iwci_salv_wd_table .
    lo_interfacecontroller =   wd_this->wd_cpifc_usg_alv( ).
    DATA lo_value TYPE REF TO cl_salv_wd_config_table.
    lo_value = lo_interfacecontroller->get_model(
    CALL METHOD lo_value->if_salv_wd_table_settings~set_cell_action_event_enabled
     EXPORTING
        value = abap_true.
  ENDIF.
2. Implement the onCellAction event as follows;
    Goto Methods tab, create a new method. Method Type- Event Handler , Event - ON_CELL_ACTION
3. Now in this  method retrive the contents of the row and calculate the value as follows.
DATA: l_element TYPE REF TO if_wd_context_element.
  DATA:ls_stru TYPE wd_this->element_cn_alv.
  DATA: l_node TYPE REF TO if_wd_context_node.
  l_node  = wd_context->get_child_node( 'CN_ALV' ).
  l_element = l_node->get_element(  r_param->index ).
  l_element->get_static_attributes( IMPORTING static_attributes = ls_stru ).
  ls_stru-last_col = ls_stru-col1+ls_stru-col2....+ ls_stru-col5. " add all the cells data
  l_element->set_static_attributes( exporting static_attributes = ls_stru ).
