React TreeList - Customize Column Headers
The TreeList generates column headers based on the names of data fields by default. For example, if a data field is "fullName", the column header text is "Full Name".
Specify the columns.caption property to change the column header text.
If you need a more specific customization, define a custom template in the columns.headerCellTemplate property. This property accepts a function or template container.
To hide column headers, assign false to the showColumnHeaders property.
