My HTML code includes an AngularJS table as shown below:
<table id="searchTable">
<thead>
<tr>
<th>Index</th>
<th>Observation</th>
<th>Reported By</th>
<th>Verified By</th>
<th>Date</th>
</tr>
</thead>
<tbody>
<tr data-ng-repeat="observation in observations| filter:searchText">
<th> {{$index + 1}} </th>
<th>{{observation.clinicalType}}</th>
<th>{{observation.reportedBy}}</th>
<th>{{observation.verifiedBy}}</th>
<th>{{observation.reportedDate}}</th>
</tr>
</tbody>
</table>
I'm facing a challenge where some columns may contain the string "NULL" and I want to highlight all instances of "NULL" in red using CSS. Can someone suggest a simple solution for this? I've been struggling with it for quite some time.
