[RizwanaHakeem]

Hi

I have to apply mattableFilter for below scenerio. But unable to filter

Class Student{
name: string;
mark: Mark[];
}
Class Mark{
science:number;
maths:number;
}

this.filterEntity=new Student();
this.filterEntity.mark = [new Mark()];

Name	{{element.name}}	Mark
{{any.science}}
