I have used the standard component u2018salv_wd_tableu2019 in my application and will be able to give example by adding a button named 'NEW__BUTTON' .
In the WDDOINIT method of the component controller, use the following code to define column name, your own buttons, visible column for the same component usage.
DATA:
lr_salv_wd_table_usage TYPE REF TO if_wd_component_usage,
lr_salv_wd_table TYPE REF TO iwci_salv_wd_table.
*Check ALV component usage
lr_salv_wd_table_usage = wd_this->wd_cpuse_alv( ).
IF lr_salv_wd_table_usage->has_active_component( ) IS INITIAL.
lr_salv_wd_table_usage->create_component( ).
ELSE.
lr_salv_wd_table_usage->delete_component( ).
lr_salv_wd_table_usage->create_component( ).
ENDIF.
*Get ALV component
lr_salv_wd_table = wd_this->wd_cpifc_alv( ).
wd_this->mr_table type ref to CL_SALV_WD_CONFIG_TABLE.
*Get ConfigurationModel from ALV Component
wd_this->mr_table = lr_salv_wd_table->get_model( ).
*Set table settings
DATA:
lr_table_settings TYPE REF TO if_salv_wd_table_settings.
lr_table_settings ?= wd_this->mr_table .
lr_table_settings->set_visible_row_count( '5' ).
lr_table_settings->set_width( '100%' ).
DATA:
lr_header TYPE REF TO cl_salv_wd_header,
l_header_text TYPE string.
lr_header = lr_table_settings->get_header( ).
l_header_text = cl_wd_utilities=>get_otr_text_by_alias( 'NEW__BUTTON' ).
lr_header->set_text( l_header_text ).
lr_header->set_tooltip( l_header_text ).
"lr_table_settings->set_selection_mode( cl_wd_table=>e_selection_mode-multi_no_lead ).
*Set functions
IF wd_this->mb_no_maintain NE abap_true.
DATA:
lr_function TYPE REF TO cl_salv_wd_function,
lr_fe_button TYPE REF TO cl_salv_wd_fe_button,
l_btn_text TYPE string.
*Add the button here for validation on the top of the ALV
*This is where you add the buttons on the same ROW.
lr_function = lr_functions->create_function( 'NEW__BUTTON' ).
CREATE OBJECT lr_fe_button.
l_btn_text = cl_wd_utilities=>get_otr_text_by_alias( 'NEW__BUTTON' ).
lr_fe_button->set_text( l_btn_text ).
lr_fe_button->set_tooltip( l_btn_text ).
lr_function->set_editor( lr_fe_button ).
After defining the buttons 'NEW__BUTTON' , handle the actions for the same using the method u2018LIST_ACTIONu2019 which should have the event as u2018ON_FUNCTIONu2019, controller as u2018interface controlleru2019 and component use as the name you have given say u2018ALVu2019.
In the method u2018LIST_ACTIONu2019, handle the actions as below. This method will have the following importing parameters.
WDEVENT Importing CL_WD_CUSTOM_EVENT
R_PARAM Importing IF_SALV_WD_TABLE_FUNCTION
method list_action .
case r_param->id .
when  'NEW__BUTTON'.
"Do the validation here-"
endcase.
endmethod.
