tablerowgroup

Tablerowgroup is a term used to describe a grouping of table rows within a tabular element. In HTML and related web standards, a table is organized into sections that separate header rows from body rows and footer rows. These sections are commonly represented by the elements thead, tbody, and tfoot, and collectively they function as tablerowgroups. Each group contains one or more table rows (tr) and serves to structure the table for rendering, accessibility, and styling.

In practice, tablerowgroups enable distinct handling of headers, body content, and footers. For example, header rows in thead are typically rendered before body rows and may be repeated when printing. Body rows in tbody usually constitute the main data portion, while tfoot can host summary or aggregate rows. This separation supports layout features such as sticky headers, zebra striping, and targeted styling.

From a programmatic perspective, the Document Object Model (DOM) exposes the table’s sections as separate objects. A table element can provide references to its header, body, and footer groups, and these groups expose their own collections of rows and methods for manipulation, such as inserting or removing rows within a specific tablerowgroup.

Styling and accessibility considerations are common reasons to use tablerowgroups. Screen readers recognize the semantic roles of thead, tbody, and tfoot, and CSS can apply different display and layout rules to each group. Practically, tablerowgroups are a foundational concept for organizing and styling complex tables across browsers and devices.
