taking into account the cell contents and style.</p>
<p>If the grid has a large number of rows, you can improve performance by using the 
<code class="paramref">topRow</code> and <code class="paramref">bottomRow</code> parameters to specify a row range. 
You can include only a few hundred rows in the process, and add some extra spacing for safety.</p>
