ARIA: aria-rowspan attribute

Description

Similar to the rowspan attribute of the <td> and <th> elements, but for cells and gridcells which are not contained in a native table, the aria-rowspan attribute defines the number of rows spanned by a cell or gridcell within a table, grid, or treegrid.

This attribute is intended for cells and gridcells which are not part of an HTML <table>. When a cell is nested in a semantic <table>, the rowspan attribute should be used when a or spans more than one row. If both are present, rowspan takes precedence over aria-rowspan. But, like all ARIA attributes, aria-rowspan only impacts the accessibility tree. It doesn't change your layout.

Note: ARIA modifies the accessibility tree and how assistive technology presents content to your users. ARIA doesn't change anything about an element's function, behavior, or appearance. When using non-semantic elements, you must use CSS to manage layout and appearance.

The value of aria-rowspan is an integer greater than or equal to 0 and less than the value which would cause the cell or gridcell to overlap the next cell or gridcell in the same column. Setting the value to 0 indicates that the cell or gridcell is to span all the remaining rows in the row group. The default value is 1.

Values

<integer>: An integer greater than or equal to 0 and less than would cause a cell to overlap the next cell in the same column.
