You probably need to specify your wildcard on both tables.

CREATE TABLE "BorujerdDistCent" as
SELECT
   "Borujerd".*, "Lorestan".*, t_distance(st_centroid("Lorestan".geometry),"Borujerd".geometry)/1000
as DistFromCntroid
FROM "Borujerd", "Lorestan"
Where "Lorestan"."Shahrestan" = 'بروجرد'
ORDER BY
   "Borujerd".abady_name ASC
