Hi @Tipuranjali
Essentially the note displayed on the UI is an HTML object contained within a <div> tag. Perhaps this might be of interest to you: Updating a Note using FD API. Basically, GET the note then, PUT the note. If the GET fails, do a POST note to create a new one.
Now how you append the HTML table itself requires some DOM manipulation for which you can use any method that you see fit. Maybe this library would help cheeriojs.
Hope this helps.
