How to change the My Account > Orders page to add fields into the view?

Hi there,

New to this template – I’ve installed the Mega Electronics theme and created an order, however the View needs updating to add Company Name into the View and a new field I want to add to the checkout form called ‘PO Number’. If possible remove Status from the view also

Right now When I go to My Account > Orders these are the fields I see – Order / Date / Status / Total

Would anyone know how to do this? Does it require some extra coding?
