IPad / IPhone - display data from website in table

I would like a small demo project to get me started. It needs to be able to download comma delimited data from a website like [login to view URL], parse that data into an array or something, then display it in a table (multicolumn if possible). The app should have a textbox to enter the url, a go button or something like that next to it, a table, all the appropriate exception handling, and it should make the network activity icon appear while downloading the data.
