This is like SPA(single page web application).

This demo is good for biegginer.

here I designed Angular form and Table. user can insert or update record using same form only.

There are input box, radio button and dropdown available in form. when user click on edit recort it fill that information to form.and change add button into update button. you can change and update that record.
