On dirait que les données ne sont pas formatées correctement ..

Voici comment votre objet de données attribué à la table devrait ressembler à:

let cars = [ 
    {"brand": "VW", "year": 2012, "color": "Orange", "vin": "dsad231ff"}, 
    {"brand": "Audi", "year": 2011, "color": "Black", "vin": "gwregre345"}, 
    {"brand": "Renault", "year": 2005, "color": "Gray", "vin": "h354htr"}, 
    {"brand": "BMW", "year": 2003, "color": "Blue", "vin": "j6w54qgh"}, 
    {"brand": "Mercedes", "year": 1995, "color": "Orange", "vin": "hrtwy34"}, 
    {"brand": "Volvo", "year": 2005, "color": "Black", "vin": "jejtyj"}, 
    {"brand": "Honda", "year": 2012, "color": "Yellow", "vin": "g43gr"}, 
    {"brand": "Jaguar", "year": 2013, "color": "Orange", "vin": "greg34"}, 
    {"brand": "Ford", "year": 2000, "color": "Black", "vin": "h54hw5"}, 
    {"brand": "Fiat", "year": 2013, "color": "Red", "vin": "245t2s"} 
]

Si vous attendez des données JSON-formated, comprennent la méthode .json():

this._cs.findAllActiveCustomerDetailsByPage(parameters).subscribe(
     (data: any) => { 
     this.customers = data.json(); 
     },`enter code here`
