Creating an internal table dynamic

Hi all,

I need to create a dynamic internal table with all the fields of a structure/table and one field of type LVC_T_STYL.

Imagine the following simple program:

PARAMETERS: p_tab  TYPE dd02l-tabname DEFAULT 'SYST'.

DATA: lo_table     TYPE REF TO data,
      lt_fieldcat  TYPE  slis_t_fieldcat_alv,
      lt_fieldcat1 TYPE lvc_t_fcat.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
  EXPORTING
    i_structure_name = p_tab
  CHANGING
    ct_fieldcat      = lt_fieldcat
  EXCEPTIONS
    OTHERS           = 99.

MOVE-CORRESPONDING: lt_fieldcat TO lt_fieldcat1.

CALL METHOD cl_alv_table_create=>create_dynamic_table
  EXPORTING
    it_fieldcatalog = lt_fieldcat1
  IMPORTING
    ep_table        = lo_table
  EXCEPTIONS
    OTHERS          = 99.

ASSIGN lo_table->* TO FIELD-SYMBOL(<wa_tab>).

Now how can I add another column of type LVC_T_STYL ?

Since it's a table I cannot add it to lt_fieldcat, I guess.

Many thanks

Please don't use CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE as explained here: Alternative to CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE | SAP Blogs

Pass the parameter I_STYLE_TABLE = 'X'.
