Hi all,
I am displaying data through and ALV table. Now I want to change the FONT only for few rows. Is this possible?
If so then do the needful to me..

I believe as you have found 'LVC_FIELDCATALOG_MERGE' would only work with the classic dynpro (SAPGUI based) version of the ALV. 
You won't be able to control the font the same way in the WDA version of the ALV.  You will need to create a custom cell editor for the column(s) in question.  You can then bind context attributes to the properties of the cell editor. You will need extra attributes in your bound context to control these settings on the row level.  Also you will be restricted by the changing the DESIGN property. This means only the values allowed for the DESIGN of the particluar UI element.  For a TextView that wouldn't be the font directly (the font of course comes from the Theme).
DATA l_salv_wd_table TYPE REF TO iwci_salv_wd_table.
  l_salv_wd_table = wd_this->wd_cpifc_alv_adv( ).
  DATA l_table TYPE REF TO cl_salv_wd_config_table.
  l_table = l_salv_wd_table->get_model( ).
  data textview type ref to CL_SALV_WD_UIE_TEXT_VIEW.
  l_column = l_table->if_salv_wd_column_settings~get_column( 'ADD_PARTICIPANTS' ).
  create object textview.
  textview->SET_TEXT_FIELDNAME( 'ADD_PARTICIPANTS' ).
  textview->set_design_fieldname( 'ADD_DESIGN' ).
  textview->set_wrapping( abap_true ).
  l_column->set_cell_editor( textview ).
DESIGN supports the following options:
Value
Visual Display
Description
emphasized
Text is highlighted in default size
groupTitle
Header for forms
This enumeration value is deprecated. Instead, use SectionHeader.
header1
Text is highlighted with font size +4 in relation to the default font size.
header2
Text is highlighted with font size +5.08 cm relation to the default font size.
header3
Text is highlighted in default size
header4
Text is highlighted in font size -1 (small) in relation to the default font size (like the legend but highlighted)
label
Text is display in the default font type. A space is always inserted after the text.
label_small
Text is displayed in default font type, as with label, onyl that font size is -1 (like the font size for header4).
legend
Text is displayed with default font type in size -1.
reference
Text is in italics and in default font size.
standard
Text is displayed in default font size. No text attributes are defined for this value.
monospace
Text is displayed in no-proportional font type. Each letter takes up the same space.
