Hi Sahil,
It is possible to set all sorts of UI elements inside the cells of a column. Those elements are called cell editors. I will explain as to how you can create a button element and set its tooltip (optional not mandatory for the button) . Then set the button as the cell editor of the button. First you need to obtain the references of all the columns into an internal table and need to modify the cell editors while looping through them.
DATA: lr_salv_wd_table TYPE REF TO iwci_salv_wd_table,
          r_table TYPE REF TO CL_SALV_WD_CONFIG_TABLE.
" Get reference to ALV component interface
lr_salv_wd_table = wd_this->wd_cpifc_alvmain( ).
" Get ConfigurationModel from ALV Component
wd_this->r_table = lr_salv_wd_table->get_model( ).
DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings,
      lr_col_header TYPE REF TO cl_salv_wd_column_header.
lr_column_settings ?= wd_this->r_table.
" Get references to all columns in an internal table
DATA: lt_columns TYPE salv_wd_t_column_ref.
lt_columns = lr_column_settings->get_columns( ).
" Loop through the column references and set the desired cells as buttons
LOOP AT lt_columns INTO ls_column.
CASE ls_column-id.
WHEN 'DBC_ICO'.
    DATA: lr_button TYPE REF TO cl_salv_wd_uie_button.
    CREATE OBJECT lr_button.
" set width to 1 to make column as small as possible
" the width is always adapted to minimum width of celleditor
ls_column-r_column->set_width( '1' ).
" image source is in the value of the cell
lr_button->set_image_source_fieldname( ls_column-id ).
" retrieve translatable text for tooltip
ls_tooltip = cl_wd_utilities=>get_otr_text_by_alias( 'NNL1/DBC' ).
CALL METHOD lr_button->set_tooltip EXPORTING value = ls_tooltip.
CALL METHOD ls_column-r_column->set_cell_editor EXPORTING value = lr_button.
