 <p>An alternative way of grouping rows is being added to <code>kableExtra</code> 0.3.0. Unlike <code>group_rows</code>, the new function <code>add_header_left</code> adopts a similar syntax with <code>add_header_above</code>. It allows users to add multiple layers of row groups, which is a limitation of <code>group_rows</code>. Currently, <code>add_header_left</code> in HTML is in good shape with exception that it doesn’t work with <code>group_rows</code>.</p>
