Customize Resource Headers
For AngularJS and Knockout apps, DevExtreme provides the dxTemplate markup component. The following code shows how to use dxTemplate to define custom templates for resource headers.

<dx-scheduler
[dataSource]="schedulerData"

[groups]="['roomId']"
resourceCellTemplate="headerTemplate">
<dxi-resource
fieldExpr="roomId"
[dataSource]="rooms" >

<div *dxTemplate="let data of 'headerTemplate'">
<i style="color: blue">{{data.text}}</i>
</div>

export default App;If you use jQuery alone, use DOM manipulation methods to combine the HTML markup for resource headers. To apply this markup, use the resourceCellTemplate callback function as shown in the following code.
JavaScript
var schedulerData = [{
text: "Meeting",
startDate: new Date("2016-04-24T09:10:00.000Z"),
endDate: new Date("2016-04-24T11:20:00.000Z"),
roomId: 1
},
// ...
];
var roomResource = {
fieldExpr: 'roomId',
dataSource: [
{ id: 1, text: 'Room101', color: 'green' },
{ id: 2, text: 'Room102', color: 'red' },
// ...
]
};
$(function () {
$("#schedulerContainer").dxScheduler({
dataSource: schedulerData,
currentDate: new Date(2016, 4, 24),
resources: [ roomResource ],
groups: [ 'roomId' ],
resourceCellTemplate: function (data, index, element) {
element.append("<i style='color: blue'>" + data.text + "</i>");
}
});
});In addition, you can use a 3rd-party template engine to customize UI component appearance. For more information, see the 3rd-Party Template Engines article.
