<h2>Conditional formatting</h2>

style="color: green; font-weight: bold">green bold</span> text
</li>
<li>all cells in the Nissan column are written in <span style="font-style: italic">italic</span></li>
<li>empty cells have <span style="background: silver">silver</span> background</li>
<li>negative numbers are written in <span style="color: red">red</span></li>
</ol>
