Dynamic context nodes

Question

Hi all,
I want to create a dynamic context in this way.  But in this example I always need a data element in the dictionary for the describe by name method --> here ZREMARK
I can use here describe_by_name( 'STRING' ) but then the column headerline is empty.
How can I set the column headerline when I use this coding?
comp-name = 'REMARK'.
comp-type ?= cl_abap_datadescr=>describe_by_name( 'ZREMARK' ).
APPEND comp TO comp_tab.
not this structure contains the fields "CONNID" and "CARRID"
  struct_type = cl_abap_structdescr=>create( comp_tab ).
now the nodeinfo is created
  node_info = wd_context->get_node_info( ).
  node_info = node_info->add_new_child_node(
    name                         = 'MY_NODE'
    is_mandatory                 = abap_false
    is_multiple                  = abap_true
    static_element_rtti          = struct_type
    is_static                    = abap_false
regards

>Is it possible to create the columns of the table control in a similar way?
Yes you can create the table and its columns dynamically in WDDOMODIFYVIEW.  Here is a sample - I'm only creating one column, but it would be easy to adapt this logic to loop through some list of fields to create the columns.
DATA lr_container TYPE REF TO cl_wd_uielement_container.
  DATA lr_input TYPE REF TO cl_wd_input_field.
  DATA lr_table TYPE REF TO cl_wd_table.
  DATA lr_caption TYPE REF TO cl_wd_caption.
  DATA lr_table_column TYPE REF TO cl_wd_table_column.
  DATA lr_table_standard_cell TYPE REF TO cl_wd_table_standard_cell.
  IF first_time = abap_true.
    lr_container  ?= view->get_element( 'ROOTUIELEMENTCONTAINER' ).
    cl_wd_table=>new_table(
      EXPORTING
        bind_data_source              = 'SFLIGHT.SFLIGHT'
        id                            = 'DYNTABLE'
      RECEIVING
         control                       = lr_table ).
    cl_wd_input_field=>new_input_field(
      EXPORTING
         bind_value             = 'SFLIGHT.SFLIGHT.CARRID'
         id                     = 'INPUT1'
      RECEIVING
        control                = lr_input ).
    lr_table_column = cl_wd_table_column=>new_table_column( ).
    lr_table_column->set_table_cell_editor( lr_input ).
    lr_caption = cl_wd_caption=>new_caption( ).
    lr_caption->set_text( 'Some text' ).
    lr_table_column->set_header( EXPORTING the_header = lr_caption ).
    lr_table->add_column( EXPORTING the_column = lr_table_column ).
*       create the layout data of the text view
    DATA lr_grid_data TYPE REF TO cl_wd_grid_data.
    lr_grid_data = cl_wd_grid_data=>new_grid_data( lr_table ).
    lr_table->set_layout_data( lr_grid_data ).
    lr_container->add_child(
      EXPORTING
        the_child = lr_table ).
  ENDIF.
