coloring a table.

[Former Member]

hi all,

I am displaying a table in webdynpro.Based on the condition the rows of the table should be in different color.

Hi Siva,

Suppose I am displaying the data from SFLIGHT in a table & I want all the rows with PRICE > 500 in one colour and the rest in another then you can proceed as follows:

I have a context node by name SFLIGHT & it has CARRID, CONNID, FLDATE & PRICE as its attributes. In addition to these 4 dictionary fields I have a 5th attribute under the same node by name COLOUR. This is of type: WDUI_TABLE_CELL_DESIGN. I would be using this for changing the table's row colour. I dont hev any special settings for my context node.

SFLIGHT node:

Cardinality: 0..n
Selection: 0..1

I design a table in my layout & am displaying only the 4 dictionary fields in the table. (i.e, while doing the binding for the table I uncheck the checkbox for COLOUR so that it wouldnt get displayed.) Now I go to each column and bind its "cellDesign" property with the context attribute COLOUR. (i.e, MAIN.SFLIGHT.COLOUR)

So now as how you would have understood while populating my table with values I would just have to fill the context attribute COLOUR with the right value to reach the desired solution.

So thats it! Now upon execution your table would show all rows which have PRICE > 500 in 1 colour & the rest in another.

If you would like to check the possible list of values which you can assign then you can check the value range of the domain WDUI_TABLE_CELL_DESIGN which is associated with the type of the same name. (i.e, WDUI_TABLE_CELL_DESIGN).

Below is the coding from WDDOINIT that I use for populating the table & attribute COLOUR with data.

method WDDOINIT .
  data: wd_node type ref to if_wd_context_node,
        lt_sflight type wd_this->elements_sflight,
        wa_sflight type wd_this->element_sflight.

  wd_node = wd_context->get_child_node( name = 'SFLIGHT' ).

*** Fetch the desired data from SFLIGHT
  
  select carrid
         connid
         fldate
         price from sflight into corresponding fields of table lt_sflight.
*** Am just trying to reduce the resultset so that it would be easier to see the output
  sort lt_sflight by price.
  delete adjacent duplicates from lt_sflight comparing price.

*** This is the main part. I loop through the data from SFLIGHT & check which rows have PRICE > 500
*** I assign different values to the COLOUR attribute when it is ( greater than 500 ) & ( less than or equal to 500 )
  loop at lt_sflight into wa_sflight.
    if wa_sflight-price > 500.
      wa_sflight-colour = '11'.
    else.
      wa_sflight-colour = '07'.
    endif.
    modify lt_sflight from wa_sflight transporting colour.
  endloop.

  wd_node->bind_table( new_items = lt_sflight ).
endmethod.
