方法dropCulomn不存在

Question

当我运行此cmd php artisan migrate：rollback时，他给我错误，为什么 发挥作用

Schema::table('pointages', function (Blueprint $table) {
            $table->integer('salarie_id')->unsigned()->after('id');
            $table->foreign('salarie_id')->references('id')->on('salaries');  
        });

功能关闭

Schema::table('pointages', function (Blueprint $table) {
             $table->dropForeign(['salarie_id']);
            $table->dropCulomn('salarie_id');
        });
