How to combine two contents of same type and display in views How to combine two contents of same type and display in views?

the following picture will clear my question.
There is a module for that, Views Merge Rows. From the project's description:


  Sometimes when you use relationships in views you get a number of rows
  with the same content in some of the fields. This results in a huge
  table (grid, list, etc.) that affects the usability of your view. The
  Views Merge Rows module provides a way to combine rows with the same
  content in the specified fields.


Keep in mind that there is a pretty straightforward guide to configure the module in the project's page that includes very descriptive screenshots.
