So to get the company name added, you can click on the one of the cells from the first column where all the cells say "company".
A pop-up menu should show on the right hand side with all the details, the first option will be "T Company" with the company name. When you hover over it, a new option will show that says "Add as Column" select it and you will be able to add the name of the company as column and it will do so for the rest of the entries too.
