HeaderTemplateDirective

Represents the column header cell template of the TreeList (more information and example). Helps to customize the table header cell for the column. To define a header template, nest an <ng-template> tag with the kendoTreeListHeaderTemplate directive inside the <kendo-treelist-column> tag.

The template context is set to the current column and then the following additional fields are passed:

• column—Defines an instance of the ColumnComponent option.
• columnIndex—Defines the current column index.
