TableView: sort="server" with iterator-generated cell content

Question

I have an htmlb:tableView that uses an iterator and sort ="SERVER".
In one of the columns, I change the text that is displayed a little bit in RENDER_CELL_START of the iterator.
  DATA lr_text  TYPE REF TO cl_htmlb_textview.
  FIELD-SYMBOLS <fs_row>  LIKE LINE OF me->t_bla.
  ASSIGN p_row_data_ref->* TO <fs_row>.
  CASE p_column_key.
    WHEN 'MY_FIELDNAME'.
      CREATE OBJECT lr_text.
      lr_text->id     = p_cell_id.
      lr_text->text   = me->get_name( <fs_row>-id ).
      p_replacement_bee = lr_text.
Now, if I click on the sort icon of the column, the table is sorted by the field 'MY_FIELDNAME', but not by the actual content of the column.
How would I achieve that?

Answer 1

this sounds almost possible.
I cannot write the new value into the original field of the table though, because I cannot be sure that the datatypes fit to each other and because I stil need the original values.
But I could of course add some more fields to the table structure (which I would not like so much), loop at the table before I use it in the tableView and write the new values into these fields.
Then, I wouldn't even need RENDER_CELL_START at all.
