  FIELD-SYMBOLS: <fs_table> TYPE STANDARD TABLE.
  FIELD-SYMBOLS: <fs_line> TYPE ANY.

  CREATE DATA dref_table TYPE TABLE OF (p_table).
  CREATE DATA dref_table_line TYPE (p_table).

  ASSIGN dref_table->* TO <fs_table>.
  ASSIGN dref_table_line->* TO <fs_line>.

Now <fs_table> will have the same structure as the database table.

try something like this

REPORT YCHATEST1.

PARAMETERS : P_TABLE LIKE DD02L-TABNAME.

DATA : IT_FIELDCAT TYPE LVC_T_FCAT,
       NEW_TABLE TYPE REF TO DATA.

FIELD-SYMBOLS : <FS> TYPE STANDARD TABLE.

ASSIGN (P_TABLE) TO <FS>.

CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
  EXPORTING
    I_STRUCTURE_NAME = <FS>
  CHANGING
    CT_FIELDCAT      = IT_FIELDCAT.

CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE
  EXPORTING
    IT_FIELDCATALOG = IT_FIELDCAT
  IMPORTING
    EP_TABLE        = NEW_TABLE.
