How to fetch array of array data in angular 2.

My json data is as follows,

[[{"pk_emp_id":5,"tenant_id":"Zone1","location_id":1,"emp_number":"sk44","prefix":"","first_name":"qqqqq","middle_name":"www","last_name":"eeee","display_name":"qqqq","full_name":"qqq qqqq","email":"[email protected]","gender":"Female","emp_type_id":2,"date_of_hire":191000,"date_of_birth":null,"manager_id":7,"phone_number":"9877654","position":"SE","responsibility":"","notes":"","contracted":"0","street":"vidyanagar","state":"Karnataka","city":"hubli","zip_code":"9898","dob":-19800000,"ssn":"","deleted":0},{"pk_empt_id":2,"empt_tenant_id":"2","empt_name":"temporary","deleted":0}] ]

I want to fetch empt_name in datatable(row data). Can any one help me out?

First go to the URL

Now suppose you want array of array of Employee

You need to create a class for example Data

export class Data {
 employees: Employee[];
and then use Data class with Observable

getBooksWithObservable(): Observable<Data[]> {
    return this.http.get(this.url).map(this.extractData);
