Working Code : https://codesandbox.io/s/proud-snowflake-d2054?file=/src/App.js
I have an Nested Array , and I want to read the values entered inside the table , also im having a option to add new text field as well . I want to know how to assign onchange function and values to these textfields.

Also how to discard values on delete button right next to text field.
Since it is an Nested array it is becoming difficult to update values on setState.
