        <p>
            Row expansion is controlled with <i>expandedRows</i> property. The column that has the expander element requires <i>expander</i> property to be enabled. Optional <i>rowExpand</i> and <i>rowCollapse</i>
            events are available as callbacks.
        </p>
        <p>
            Expanded rows can either be an array of row data or when <i>dataKey</i> is present, an object whose keys are strings referring to the identifier of the row data and values are booleans to represent the expansion state e.g.
            <i>&#123;'1004': true&#125;</i>. The <i>dataKey</i> alternative is more performant for large amounts of data.
