i am using the salv_wd_table.
any piece of code is appreciated.

Bobby,
If let's say you are build a ALV table to output 'SFLIGHT' table, and you want PLANETYPE '747-400' to be displayed in green, and PLANETYPE '146-200' displayed in red.
Also, let's just say, you already had a context node 'SFLIGHT_NODE' that is mapped to the external node 'DATA' of your ALV.
Now:
1.  you need to modify the context node 'SFLIGHT_NODE' to add an attribute -- say 'CELL_COLOR' of type 'WDY_UIE_LIBRARY_ENUM_TYPE' -- to the SFLIGHT_NODE (note, you need to delete 'DICTIONARY structure' that is bind to the 'SFLIGHT_NODE' node, otherwise, you will not be able to create addition attributes)
After, you will have something like this for your context node .
  CONTEXT
    --> SFLIGHT_NODE  
> CARRID
> CONNID
> FLDATE
> PRICE
> PLANETYPE
> <and any other attributes you had pulled from SFLIGHT)
> CELL_COLOR (TYPE WDY_UIE_LIBRARY_ENUM_TYPE)
2.  In your supply function to the 'SFLIGHT_NODE', you now need to supply the data to this newly added attribute:
METHOD supply_sflight_node .
** data declaration
  DATA:
    itab_sflight_node            TYPE if_componentcontroller=>elements_sflight_node,
    stru_sflight_node            LIKE LINE OF itab_sflight_node.
** read sflight data
  SELECT * FROM sflight INTO CORRESPONDING FIELDS OF TABLE itab_sflight_node.
** populate the 'CELL_COLOR' field
  LOOP AT itab_sflight_node INTO stru_sflight_node .
    IF stru_sflight_node-planetype = '747-400'.
      stru_sflight_node-cell_color = CL_WD_TABLE_COLUMN=>E_CELL_DESIGN-GOODVALUE_DARK .
     ELSEIF stru_sflight_node-planetype = '146-200'.
      stru_sflight_node-cell_color = CL_WD_TABLE_COLUMN=>E_CELL_DESIGN-BADVALUE_DARK .  
    ELSE.
      stru_sflight_node-cell_color = CL_WD_TABLE_COLUMN=>E_CELL_DESIGN-STANDARD .
    ENDIF.
    modify itab_sflight_node from stru_sflight_node.
  ENDLOOP.
** bind all the elements
  node->bind_table(
    new_items =  itab_sflight_node
    set_initial_elements = abap_true ).
ENDMETHOD.
3. Now, you need to obtain the configuration model of the ALV and config it before display.  (say you have an method does this 'init_alv_table_settings', and it is called from your view's wddoinit() method)
METHOD init_alv_table_settings .
  DATA: l_ref_cmp_usage TYPE REF TO if_wd_component_usage.
  l_ref_cmp_usage =   wd_this->wd_cpuse_alv_table( ).
  IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.
    l_ref_cmp_usage->create_component( ).
  ENDIF.
  DATA: l_ref_interfacecontroller TYPE REF TO iwci_salv_wd_table .
  l_ref_interfacecontroller =   wd_this->wd_cpifc_alv_table( ).
  DATA:
  node_sflight_node                   TYPE REF TO if_wd_context_node .
  node_sflight_node = wd_context->get_child_node( name = if_flights_view=>wdctx_sflight_node ).
  CALL METHOD l_ref_interfacecontroller->set_data
    EXPORTING
      r_node_data = node_sflight_node.
**  get ConfigurationModel from ALV Component
  DATA:    lr_table TYPE REF TO cl_salv_wd_config_table.
  lr_table = l_ref_interfacecontroller->get_model( ).
** change the color of the cell
  DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings.
  DATA: lr_column TYPE REF TO cl_salv_wd_column.
  lr_column_settings ?= lr_table.
  lr_column = lr_column_settings->get_column( 'PLANETYPE' ).
  DATA: lr_input_field TYPE REF TO cl_salv_wd_uie_input_field.
  CREATE OBJECT lr_input_field EXPORTING value_fieldname = 'PLANETYPE'.
  lr_column->set_cell_editor( lr_input_field ).
  lr_column->set_cell_design_fieldname( value = 'CELL_COLOR' ).
ENDMETHOD.
Compile and activate your code.
