Description

Bug, feature request, or proposal:

Proposal

What is the expected behavior?

Be able to add custom controls to headers along with matSort

What is the current behavior?

It is possible to add custom controls e.g.

<ng-container matColumnDef="to">
    <mat-header-cell *matHeaderCellDef>
      <div class="vbox">
        To
        <input [(ngModel)]="filter.to">
      </div>
    </mat-header-cell>
    <mat-cell *matCellDef="let element">{{element.to}}</mat-cell>
  </ng-container>

However this does not work with matSort

What are the steps to reproduce?

Providing a StackBlitz reproduction is the best way to share your issue. StackBlitz starter: https://goo.gl/wwnhMV

What is the use-case or motivation for changing an existing behavior?

I need individual filter controls for each column in the table, all the examples use a single filter field.

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Is there anything else we should know?

Guide contributeur

Direction de recherche: Review the Angular Material table sorting API (matSort) and existing custom sort header examples. The goal is to produce documentation that guides users on integrating custom controls like input fields into sortable headers. Look at the current table documentation and the source code for mat sort header to understand the interaction. No linked PRs or comments provide additional direction.
