Need information on Dynamic internal table

Question

Hi All,
I need some information on dynamic internal table.
I want what are the field names and the values in dynamic internal table.
Is there any function module, which tells us the field names and values of corresponding fields from a dynamic internal table ?
Thank you very much in advance.

Hi,
Program to display/edit database tables dynamically.
REPORT  zdyn_table_display.
PARAMETERS: p_table TYPE tabname OBLIGATORY,
            p_rows  TYPE I.
* Creation of dynamic internal table
DATA: lv_dref             TYPE REF TO data.
FIELD-SYMBOLS: <fs_table> TYPE STANDARD TABLE.
DATA: lv_table  TYPE  string.
START-OF-SELECTION.
* Dynamic internal table.
  CREATE DATA lv_dref       TYPE TABLE OF (p_table).
  ASSIGN lv_dref->* TO <fs_table>.
  IF sy-subrc  EQ 0.
*    EXIT.
  ENDIF.
data i type i.
* Get the data
  SELECT  *
        FROM (p_table)
        UP TO p_rows ROWS
        INTO TABLE <fs_table>.
  CONCATENATE 'Table contents : ' p_table INTO lv_table.
* display the table control.
  CALL FUNCTION 'STC1_FULLSCREEN_TABLE_CONTROL'
    EXPORTING
      header            = lv_table
      tabname           = p_table
      no_button         = space
    TABLES
      table             = <fs_table>
    EXCEPTIONS
      no_more_tables    = 1
      too_many_fields   = 2
      nametab_not_valid = 3
      handle_not_valid  = 4
      OTHERS            = 5.
  IF sy-subrc  EQ 0.
    EXIT.
  ENDIF.
Getting internal table definition 
Try this...
DATA : l_descr_ref TYPE REF TO cl_abap_structdescr.
l_descr_ref ?= cl_abap_typedescr=>describe_by_data( itab ).
Now l_descr_ref->components holds the entire list of fields in itab.
Thanks & Regards,
