React Forms:

React Table with Add New Row Form

We have a form post using React at the top of the page. This form takes information such as first and last name and email from the user and by clicking on the button below the text fields, the information is added to the table. This table also allows you to delete added rows. By clicking on each row of the table, the color of that row becomes purple and blue one by one.
