Highlighting a cell in a table when a word is included

I have a table in which I would like to highlight when a special character appears.
An example below.

When there is a date entered on 11.2020, the cell should not be highlighted, but when the entry 11.2020+ appears, the background of the text will change to red. How to set such a mask?

My code

<td>
<div style="background-color:red; color:white; font-weight:bold"><span ng-if="data.data=='11.2020'">{{data.data}}</span></div>
</td>
