Remove a column in SALV

Hi,

I am using SALV for display.

In this I am using the factory method as below :-

Data :   ref_docking_hdr       TYPE REF TO cl_gui_docking_container,

            ref_hdr         TYPE REF TO cl_salv_table.

          cl_salv_table=>factory(
          EXPORTING
            r_container    = ref_docking_hdr
          IMPORTING
            r_salv_table   =  ref_hdr
          CHANGING
            t_table        = t_header ).

t_header is pointing to some structure which is being used in some other programs as weel. This structure is enhanceed with the new field which is of type table.

So I am getting the dump when the display method is being called. I need to remove that column.

I tried to get the columns

   Get column definition
    l_ref_columns = ref_hdr->get_columns( ).

But the method REMOVE_COLUMN is protected for CL_SALV_COLUMNS.  So kindly suggest how can I remove the column.

Thanks in advance.
