ARIA: aria-rowcount attribute

Some tables have hundreds, even millions, of rows. Even for tables with fewer rows, loading only a subsection of rows may be a design requirement, improve performance, or improve user experience. When only a subset of rows are loaded, you do need to let all users know that only a subset of the data is being displayed. The aria-rowcount attribute is used to define the total number of rows in a table, grid, or treegrid.

If all of the rows are loaded and in the DOM, you don't need to include aria-rowcount as browsers automatically count the total number of rows. However, if the rows aren't all present in the DOM at any time, this attribute is needed to provide the number of rows when the full table size is known and to tell the browser to not automatically count the rows when the total number of rows is not known.
