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".

DevExtreme HTML5 JavaScript jQuery Angular Knockout UI component TreeList ColumnHeaders

Specify the columns.caption property to change the column header text.

App.js


import React from 'react';
 
import 'devextreme/dist/css/dx.light.css';
 
import TreeList, {
    Column
} from 'devextreme-react/tree-list';
 
export default function App() {
    return (
        <TreeList ... >
            <Column dataField="CompanyName" caption="Company" />
        </TreeList>
    );
}

If you need a more specific customization, define a custom template in the columns.headerCellTemplate property. This property accepts a function or template container.

App.js


import React from 'react';
import 'devextreme/dist/css/dx.light.css';
import TreeList, {
    Column
} from 'devextreme-react/tree-list';
 
const renderTitleHeader = (data) => {
    return <p style={{ font-size: '16px' }}>{data.column.caption}</p>;
}
const renderAddressHeader = () => {
    return <i style={{ color: 'black' }}>Mailing Address</i>;
}
 
export default function App() {
    return (
        <TreeList ... >
            <Column
                dataField="Title"
                caption="Position"
                headerCellRender={renderTitleHeader}
            />
            <Column
                dataField="Address"
                headerCellRender={renderAddressHeader}
            />
        </TreeList>
    );
}

To hide column headers, assign false to the showColumnHeaders property.

App.js


import React from 'react';
 
import 'devextreme/dist/css/dx.light.css';
 
import TreeList from 'devextreme-react/tree-list';
 
export default function App() {
    return (
        <TreeList ...
            showColumnHeaders={false}>
        </TreeList>
    );
}
