I`m a newbie to javascript and/or ajax and I want to develop an app which takes reports handwriting out of operator duties. Here you have a picture with what I did by now. http://i49.tinypic.com/51593p.jpg
Behind is a report made in HTML and CSS. When user clicks on a button to add a product, the small form in front appear and he inputs the properties of the current product. When he finish, the app must insert data collected into mysql(i`ve already did it) but my big issue is how to show the properties he already submitted in the main table, to the first column available without refreshing the page. I'm trying to learn about ajax and javascript but I really need to solve that issue fast and thought that you can help with some references, maybe another programming language can help me.

Thanks in advance for your answers,
