Compare row from one data table in another

I need to check each row of first datatable in second datatable and if match is found based on primary key coloum value,then cell by cell comparison needs to be done for rows of both data table.Can anyone explain the logic for it?

@rahul_kumar4 Welcome to Uipath community!

  1. You can use two for each loop activity and a if condition activity for comparison

  2. You can use a for each loop and a filter data table activity

  3. You can also use LINQ for comparison
