This sample demonstrates the Gantt header template feature. In this sample, custom icons are displayed in the column headers.
DEMO
SOURCE
The Gantt provides a way to define a custom element in the header element. The
columns -> headerTemplate property accepts either string or HTML element`s ID value,
which will be used as the template for the header cell.
In this demo, we have rendered the customized template for all column headers.
