Design Studio conditional formatting on SAP HANA

I am trying to conditionally format a crosstab. I am using a HANA datasource.

There is an article that says the query could return a value, such as:<circle></circle><alert1>4290</alert1>. Then CSS could be used to format the cell that contains the value.

In the HTML, it creates this:

<circle></circle><alert1>4290</alert1>,

However, when I copy it, I get this (maybe the same?)

<div id="__cell6_contentDiv" tabindex="-1" class="sapzencrosstab-HeaderCellContentDiv" style="width: 207px;">&lt;circle&gt;&lt;/circle&gt;&lt;alert1&gt;4290&lt;/alert1&gt;</div>

The article, then states that CSS could be used to format the data. However, the crosstab simply shows: <circle></circle><alert1>4290</alert1>

Has anybody successfully used conditional formatting on a crosstab, not using a BEx query? Or, have any ideas how to make an idea like the one above work?
