/**
 * Represents the header cell template of the Gantt columns.
 *
 * Use this directive to customize the table header cell for a column.
 * To define a header template, nest an `<ng-template>` tag with the
 * [`kendoGanttHeaderTemplate`](https://www.telerik.com/kendo-angular-ui/components/gantt/api/headertemplatedirective) directive inside the `<kendo-gantt-column>` tag.
 *
 * The template context provides:
 * * `column`&mdash;The current [`ColumnComponent`](https://www.telerik.com/kendo-angular-ui/components/gantt/api/ganttcolumncomponent).
 * * `columnIndex`&mdash;The current column index.
 *
 * @example
 * ```html
 * <kendo-gantt-column>
 *   <ng-template kendoGanttHeaderTemplate let-column let-columnIndex="columnIndex">
 *     Custom Header for {{ column.field }} ({{ columnIndex }})
 *   </ng-template>
 * </kendo-gantt-column>
 * ```
