This allows for the header to both\n  be focusable, and have screen readers read out its `aria-sort` state. We prefer this approach\n  over having a button with an `aria-label` inside the header, because the button's `aria-label`\n  will be read out as the user is navigating the table's cell (see #13012).\n\n  The approach is based off of: https://dequeuniversity.com/library/aria/tables/sf-sortable-grid\n-->\n<div class=\"mat-sort-header-container mat-focus-indicator\"\n     [class.mat-sort-header-sorted]=\"_isSorted()\"\n     [class.mat-sort-header-position-before]=\"arrowPosition == 'before'\"\n     [attr.tabindex]=\"_isDisabled() ? null : 0\"\n     role=\"button\">\n\n  <!--\n    TODO(crisbeto): this div isn't strictly necessary, but we have to keep it due to a large\n    number of screenshot diff failures.
