Table issue

Question

Hello all,
My problem could be easy..however, I am having difficulty finding documentation.  I'll start with a simple question, leaving out some of the complexities, in the hopes of getting right to the gist of the problem.
I would like to make a single cell in a standard web dynpro table UI control read only.  This is at cell level, not column.  I would like, for instance, in a column the ability to pick 1 cell from 1 row in that column and make it read only while the other cells in that column are editable.
Hopefully this is clear enough to get us started

hI,
if there is a node general_data and subnode user_entities and table is bound to user_entities node and user_entity is an attribute of node  then user_entities.Bind the property of a column
to an attribute 'DISABLE' which is of type WDY_BOOLEAN.
data: lo_set                     TYPE        wdr_context_element_set,
         lr_result_table            TYPE REF TO cl_wd_table,
         lo_nd_general_data         TYPE REF TO if_wd_context_node,
         lo_nd_user_entities        TYPE REF TO if_wd_context_node.
FIELD-SYMBOLS :
     <ls_element>             TYPE REF TO    if_wd_context_element.
lo_nd_user_entities = lo_nd_general_data->get_child_node( name = wd_this->wdctx_user_entities ).
  lo_set = lo_nd_user_entities->get_elements( ).
  IF lo_set IS NOT INITIAL.
    LOOP AT lo_set  ASSIGNING <ls_element>.
      <ls_element>->get_attribute(
        EXPORTING name  = 'user_entity'
        IMPORTING value = lv_user_entity ).
      IF lv_user_entity EQ 'User Group'.
If the User Entity is a User Group then the UI element to be shown as read only
        <ls_element>->set_attribute(
           EXPORTING value = 'X'
                     name  = 'DISABLE' ).
ENDIF.
