Dynamic table columns in web dynpro abap

Question

Hi,
In my current project I have got a requirement whose solution I am not able to figure out.
My requirement is this:
I will have a table containig budget owners name(since its compensation management in HR).There will be a table popin inside this table on the click of the personal number of the budget owner. Now the table popin will have another table with all employees name under that particular budget owner.
The problem is that the table inside the popin will not be having fixed columns.Actually the columns will be coming from a standard java web dynpro application (say in the form of an internal table).
My requirement is this how can this be handled?Can we include all the possible columns in the node(which i bind to the child table) and make them visible/invisible during runtime? or create a dynamic node and assign it to the table(but in this case a node needs to be bound to the table during design time,what to bind?)  ?
Can u please help along with code snippets.
Thanks and Regards,
Saikat.

Thnx for the input.
I am abke to make the table columns inside the popin visible/invisible.
I have a tabstrip.Indise one of the tabs is my main table and inside one of the columns is the popin.Inside that a transparent container and finally the table inside that.
This is the code that worked for me.
METHOD wddomodifyview .
  DATA lr_root_container TYPE REF TO cl_wd_uielement_container.
  DATA lr_table_popin TYPE REF TO cl_wd_table_popin.
  DATA lr_transparent_container TYPE REF TO cl_wd_transparent_container.
  DATA lr_table TYPE REF TO cl_wd_table.
  DATA lr_table_column TYPE REF TO cl_wd_table_column.
  DATA lr_table_in_table_popin TYPE REF TO cl_wd_table.
  DATA lr_node_header_node TYPE REF TO if_wd_context_node.
  DATA lr_node_item_node TYPE REF TO if_wd_context_node.
  DATA lr_tabstrip TYPE REF TO cl_wd_tabstrip.
  DATA lr_tab TYPE REF TO cl_wd_tab.
  data lr_tc type ref to CL_WD_TRANSPARENT_CONTAINER.
  data lr_table2 type ref to cl_wd_table.
  DATA lr_table2_column TYPE REF TO cl_wd_table_column.
  IF first_time = abap_false.
    lr_root_container ?= view->get_element( 'ROOTUIELEMENTCONTAINER' ).
    lr_tabstrip ?= lr_root_container->get_child( id = 'TABSTRIP1' ).        "GETTING THE TABSTRIP
    lr_tab      ?= lr_tabstrip->get_tab( id = 'TAB1' ).        "GETTING THE TAB INSIDE TABSTRIP
    lr_table    ?= lr_tab->GET_CONTENT( ).      "GETTING THE CONTENT(TABLE IN THIS CASE) INSIDE TABSTRIP
    lr_table_column ?= lr_table->get_grouped_column( id = 'TABLE_MAIN_PERNR' ).   "GETTING THE COLUMN INSIDE THE TABLE
    "Table popin
    lr_table_popin ?=  lr_table_column->GET_POPIN( ).   "GETTING THE POPIN INSIDE THE TABLE
    lr_tc  ?= lr_table_popin->GET_CONTENT( ).   "GETTING THE CONTENT(TRANSPARENT CONTAINER IN THIS CASE)INSIDE THE TABLE
    lr_table2 ?= lr_tc->get_child( id = 'TABLE_EMPLOYEE' ).        "GETTING THE EMPLOYEE TABLE INSIDE THE TRANSPARENT CONTAINER
    lr_table2_column ?= lr_table2->get_grouped_column( id = 'TABLE_EMPLOYEE_PERNR' ).   "GETTING THE COLUMN INSIDE THE TABLE
    lr_table2_column->SET_VISIBLE( '02' ).  "SETTING VISIBILITY FOR THE COLUMN
  ENDIF.
ENDMETHOD.
But I'm still considering the dynamic node concept.Lets see if this works out or not.If not then I'll have to go for the dynamic node thing.
