/**
* Represents the column header cell template of the TreeList
* ([more information and example]({% slug templates_columns_treelist %}#toc-header-template)).
* Use this directive to customize the table header cell for the column.
* To define a header template, nest an `<ng-template>` tag with the
* [`kendoTreeListHeaderTemplate`]({% slug api_treelist_headertemplatedirective %}) directive inside the `<kendo-treelist-column>` tag.
*
* The template context is set to the current column and provides the following fields:
* - `column`—Defines an instance of the [`ColumnComponent`]({% slug api_treelist_columncomponent %}) option.
* - `columnIndex`—Defines the current column index.
*
* @example
* ```html
* <kendo-treelist-column field="name">
* <ng-template
* kendoTreeListHeaderTemplate
* let-column>
* {{ column.field }}
* </ng-template>
* </kendo-treelist-column>
* ```
