Creating a UI that displays data from a draft table, allows editing, and then either submitting it to a final table or saving it back to the draft table involves a combination of HTML, JavaScript, and potentially CSS.
If you are not well versed in these technologies, I recommend checking one of the tons of plugins available for JS that accomplish what you are looking for. Here is a couple of them:

Hope this helps
