Color some Cells in WD ALV

Question

Hello,
im trying to Color some Cells in a Webdynpro ALV.
So far i found out that there are maybe two ways:
one like this with WDUI_TABLE_CELL_DESIGN
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f0625002-596c-2b10-46af-91cb31b71393
but i didnt find out, how to color specified Cells. With this example it is only possible to color the column by the saved color.
the other way is to append a color table to ich column LVC_T_SCOL
and after that
*   We will set this COLOR table field name of the internal table to
*   COLUMNS tab reference for the specific colors   
TRY.       
lo_cols_tab->set_color_column( 'T_COLOR' ).     
CATCH cx_salv_data_error.                         "#EC NO_HANDLER   
ENDTRY.

i hope someone can help me.

Hi ,
Check this thread, [https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f0625002-596c-2b10-46af-91cb31b71393]
In your case you will have  to create 1 attribute ( type WDY_UIE_LIBRARY_ENUM_TYPE ) for every column. ( for eg: c1, c2, c3 ,c4 , c5 for pt1 pt2 pt3 pt4 pt5 respectively ) and bind it as follows,
*---------- Column settings
  DATA: l_column_settings TYPE REF TO if_salv_wd_column_settings.
  l_column_settings ?= lo_value.
* Get columns
  DATA: lt_columns TYPE salv_wd_t_column_ref ,
        ls_columns TYPE salv_wd_s_column_ref .
  DATA: l_column_header  TYPE REF TO cl_salv_wd_column_header .
  lt_columns = l_column_settings->get_columns( )              .
  LOOP AT lt_columns INTO ls_columns                          .
    CASE ls_columns-id                                        .
      WHEN 'PT1'                                            .
        l_column_header = ls_columns-r_column->get_header( )  .
        l_column_header->set_ddic_binding_field(
           if_salv_wd_c_column_settings=>ddic_bind_none )     .
        ls_columns-r_column->set_cell_design_fieldname( value = 'C1' ). "binding C1 is attribute
      WHEN 'PT2'                                            .
        l_column_header = ls_columns-r_column->get_header( )  .
        l_column_header->set_ddic_binding_field(
           if_salv_wd_c_column_settings=>ddic_bind_none )     .
        l_column_header->set_text( 'Item No' )                .
        ls_columns-r_column->set_cell_design_fieldname( value = 'C2' ). " binding
       ........similarly continue for all the columns.
Now modify your internal table based on your condition and set the required color as follows,
  LOOP AT lt_alv INTO ls_alv.
          if pt1 is lowest. 
            ls_alv-color1 = '02'. " green
          elseif pt2 is lowest.
            ls_alv-color2 = '03'.  "red
          endif.
          MODIFY lt_alv FROM ls_alv INDEX sy-tabix.
        ENDLOOP.
* Bind Data to ALV
        cn_alv->bind_table( lt_alv ).
Hope it helps!
