How to use clrDgItemsTrackBy for datagrid?

[kumar-tadepalli]

Hi All,

For *ngFor we can pass trackBy function.
<clr-dg-row *ngFor="let row of rows; index as i; trackBy: trackByRowName" [clrDgItem]="row" >

I'm trying to apply the same for smart iterator(*clrDgItems) and going through the documentation and found that clrDgItemsTrackBy in APIs which is not clear on how to use( no example given)?
Can some one provide example snippet of where and how it has to be used?

Regards,
Kumar
