I'm trying to add a icon to to the table header of an Angular Data Table. What am I missing?
Also, I want to make this clickable in order to show a modal. What should I add?
<th mat-header-cell *matHeaderCellDef mat-sort-header> Action Name </th>
<mat-icon svgIcon="thumbs-up" aria-hidden="false" aria-label="Example thumbs up SVG icon"></mat-icon>
<td mat-cell *matCellDef="let action"> {{action.actionName}} </td>
</ng-container>````
