You can customise the appearance of header and content of the particular column using the customAttributes property.

To customize the Tree Grid column, follow the given steps:

Step 1:

Create a CSS class with custom style to override the default style for rowcell and headercell.

.e-treegrid .e-rowcell.customcss{
    background-color: #ecedee;
    font-family: 'Bell MT';
    color: 'red';
    font-size: '20px';
}

.e-treegrid .e-headercell.customcss{
    background-color: #2382c3;
    color: white;
    font-family: 'Bell MT';
    font-size: '20px';
}

Step 2:

Add the custom CSS class to particular column by using customAttributes property.

<e-column field='TaskName' headerText='Task Name' width='170' [customAttributes]='customAttributes'></e-column>
