"An instance of iPad / iPhone UITableView (or simply, a table view) is a means for displaying and editing hierarchical lists of information.
A table view in the UIKit framework is limited to a single column because it is designed for a device with a small screen. UITableView is a subclass of UIScrollView, which allows users to scroll through the table, although UITableView allows vertical scrolling only.
A table view is made up of zero or more sections, each with its own rows. Sections are identified by their index number within the table view, and rows are identified by their index number within a section. Any section can optionally be preceded by a section header, and optionally be followed by a section footer."
