iOS Multiple Columns in UITableView
If you are looking for something that looks like an Excel spreadsheet then I would recommend the
MDSpreadview class. The source is available at http://mochidev.com/open. It looks pretty slick but bogs down if you have a lot of data to display.
Other than that, you should probably just create your own
UITableViewCell. It's pretty easy with the new Storyboards of iOS5 and you can handle millions of cells of data.
