const rowheader
A cell containing header information for a row in a grid.
Rowheader can be used as a row header in a table or grid. The rowheader establishes a relationship between it and all cells in the corresponding row. It is a structural equivalent to setting scope='row' on an HTML th element.
Authors MUST ensure elements with role rowheader are contained in, or owned by, an element with the role row.
