How can I change the cells that have a space or any separator to be black in color?
This snippet shows my HTML code:
<table >
<thead class="table table-bordered table-responsive">
<tr *ngFor="let ligne of grilleHaut">
<td *ngFor="let charac of ligne.tabDesCar">{{charac}}</td>
</tr>
</thead>
</table>
