A table view section is a logical grouping of rows within a tabular user interface component, commonly used in graphical frameworks such as iOS’s UITableView and similar list controls. Sections help organize related items, improve scannability, and support header and footer content that describes or contextualizes the enclosed rows.

Typical elements of a section include a header, one or more rows (cells), and an optional footer. Headers and footers may be text-only or custom views and are often used for titles, summary information, or section-level controls. Sections can be static (defined at design time) or dynamic (created and modified at runtime), allowing flexible presentation of varying data sets.

Implementation patterns vary by framework but usually require the data source to report the number of sections and the number of rows per section. Common callbacks include methods to provide header/footer content, cell configuration, and support for editing operations such as insertion, deletion, and reordering within a section. Performance considerations include cell reuse and efficient updates to minimize layout passes and animations.

Accessibility and usability practices include providing descriptive header text, ensuring logical keyboard and focus order, and grouping related controls so assistive technologies present coherent context. Well-designed sections enhance readability and navigation in complex lists without adding excessive visual complexity.
