Hello.
I guess you want to do that with Web Dynpro.
So you need a function which is called, when your click-event is triggered.
And within your function you need something like that:
DATA lo_node_of_table TYPE REF TO if_wd_context_node.
DATA lo_some_other_node TYPE REF TO if_wd_context_node.
DATA lo_element TYPE REF TO if_wd_context_element.
DATA ld_counter TYPE i.
DATA ld_value TYPE i.
DATA ld_sum TYPE i.
lo_node_of_table = wd_context->path_get_node( path = `PATH_TO.CONTEXT_NODE` ).
ld_counter = lo_node_of_table->get_element_count( ).
  DO ld_counter TIMES.
    lo_element = lo_nd_in->get_element( index = sy-index ).
    lo_element->get_attribute(
      EXPORTING name = 'FIELD_NAME'
        IMPORTING value = ld_value ).
    ld_sum = ld_sum + ld_value.
  ENDDO.
lo_some_other_node->set_attribute( name = 'SUM_OF_SOMETHING' value = ld_sum ).
Please reply if you meant something else.
