Hi,
You need to create the Dynamic Internal table for this one ..
type-pools : abap.
  field-symbols: <dyn_table> type standard table,
               <dyn_wa>,
               <dyn_field>.
  data: dy_table type ref to data,
      dy_line  type ref to data,
      xfc type lvc_s_fcat,
      ifc type lvc_t_fcat.
  selection-screen begin of block b1 with frame.
parameters: p_table(30) type c default 'T001'.
selection-screen end of block b1.
  start-of-selection.
    perform get_structure.
  perform create_dynamic_itab.      **********Creates a dyanamic internal table**********
  perform get_data.
  perform write_out.
  form get_structure.
  data : idetails type abap_compdescr_tab,
       xdetails type abap_compdescr.
  data : ref_table_des type ref to cl_abap_structdescr.
  * Get the structure of the table.
  ref_table_des ?= 
      cl_abap_typedescr=>describe_by_name( p_table ).
  idetails[] = ref_table_des->components[].
    loop at idetails into xdetails.
    clear xfc.
    xfc-fieldname = xdetails-name .
    xfc-datatype = xdetails-type_kind.
    xfc-inttype = xdetails-type_kind.
    xfc-intlen = xdetails-length.
    xfc-decimals = xdetails-decimals.
    append xfc to ifc.
  endloop.
  endform.
  form create_dynamic_itab.
  * Create dynamic internal table and assign to FS
  call method cl_alv_table_create=>create_dynamic_table
               exporting
                  it_fieldcatalog = ifc
               importing
                  ep_table        = dy_table.
    assign dy_table->* to <dyn_table>.
  * Create dynamic work area and assign to FS
  create data dy_line like line of <dyn_table>.
  assign dy_line->* to <dyn_wa>.
  endform.
  form get_data.
  * Select Data from table.
  select * into table <dyn_table>
             from (p_table).
  endform.
   Write out data from table.
  loop at <dyn_table> into <dyn_wa>.
    do.
      assign component  sy-index  
         of structure <dyn_wa> to <dyn_field>.
      if sy-subrc <> 0.
        exit.
      endif.
      if sy-index = 1.
        write:/ <dyn_field>.
      else.
        write: <dyn_field>.
      endif.
    enddo
  endloop.
