I am getting problem with internal table & work area declaration.

I am working with 'makt' table ..with the table makt i need to work with styles attributes ..so i declared like this

TYPES : BEGIN OF ty_makt,

         matnr TYPE makt-matnr,

         spras TYPE makt-spras,

         maktx TYPE makt-maktx,

         maktg TYPE makt-maktg,

         celltab TYPE lvc_t_styl,

       END OF ty_makt.

DATA : i_makt TYPE TABLE OF ty_makt.

DATA : wa_makt TYPE ty_makt .

    But end of program i need to update dbtable "makt"...i am getting problem with internal table & work area declaration.

i think makt table fields mapping and internal table/work area mapping is not correct. so please help me to get out from this.
