Adding Custom Column to "Item List"

Hey,
I was wondering if i could do something like shown in the picture (dynamically linking to a external website like sharepoint).
I cant seem to find an option in the settings. do i need to edit the code?

thx,

if you are working in frappe/erpnext.
so, you are going to your doctype >> sharepoint field >> In List View (check box) this check box is checked(click) and save.
