How to change 3rd value of datarow based on 1st value without using loop

image

from above image i just want to add status for specific names(which i am getting from 2nd datatable, storing in variable inside for each) as active, directly on 1st datatable without using any loop.

like if name= sam then status=active.

i want to perform this action directly on datatable and want to implement it without using any loop.
(note: 1st datatable will contains data like name and add with blank status column)

you can use lookup data table, but still you need loop.
