How to add link to people picker field

Question

Hi,

 

I am facing one issue related to people and group field.

 

I have created one custom list in SharePoint online, In that I have out of the box column "created by". Now I have created one view to show some data on page. But the requirement is that whenever any user clicks on that user name which is present in created by column it should open in mail. So now I have to add "mailto:useremail" for that particular column.

 

Please let me know.

 

I have tried using Calculated column but it is now allowing to take created by column in formula.
