How to include or exclude an attribute from the HTML in Angular 4

Well, I solved it as follow:

<mat-header-cell *matHeaderCellDef [mat-sort-header]=" column!='actions' ? column : null " [disabled]=" column=='actions' ? true : false " >

Needed to bind the disabled property.

CoderX's answer is the best approach for your question. but there might come a scenario where you need to render a separate template based on condition. In such a case you can do it like below:

<ng-container *ngIf="columnAction=='sort'; else noSort">
  <mat-header-cell *matHeaderCellDef mat-sort-header />          
</ng-container>

<ng-template #noSort>
  <mat-header-cell *matHeaderCellDef />         
</ng-template>
