Мой источник данных похож на ниже
[{"isGroup":true,"groupName":"MV Reddy","items":[{"id":1,"name":"MV Reddy","verticalid":5,"vertical":"Colocation - Large > 20 Racks","target":"150","sap":"80","colo":"20","others":"50","quarter":1,"year":2019},{"id":10,"name":"MV Reddy","verticalid":6,"vertical":"Govt","target":"150","sap":"80","colo":"20","others":"50","quarter":1,"year":2020}]},{"isGroup":true,"groupName":"Neeraj Jha","items":[{"id":2,"name":"Neeraj Jha","verticalid":4,"vertical":"Alliances","target":"70","sap":"20","colo":"30","others":"20","quarter":2,"year":2019},{"id":5,"name":"Neeraj Jha","verticalid":4,"vertical":"Alliances","target":"150","sap":"80","colo":"20","others":"50","quarter":1,"year":2019}]},{"isGroup":false,"groupName":"Suresh Rathod","items":[{"id":3,"name":"Suresh Rathod","verticalid":3,"vertical":"C4C India (Public Cloud)","target":"100","sap":"20","colo":"30","others":"50","quarter":1,"year":2019}]},{"isGroup":false,"groupName":"Arun Dubey","items":[{"id":4,"name":"Arun Dubey","verticalid":6,"vertical":"Govt","target":"150","sap":"80","colo":"20","others":"50","quarter":4,"year":2019}]},{"isGroup":true,"groupName":"Atin Singh","items":[{"id":6,"name":"Atin Singh","verticalid":5,"vertical":"Colocation - Large > 20 Racks","target":"150","sap":"80","colo":"20","others":"50","quarter":1,"year":2020},{"id":7,"name":"Atin Singh","verticalid":2,"vertical":"IAAS and Rest of Ctrls Services","target":"150","sap":"80","colo":"20","others":"50","quarter":1,"year":2020},{"id":8,"name":"Atin Singh","verticalid":3,"vertical":"C4C India (Public Cloud)","target":"150","sap":"80","colo":"20","others":"50","quarter":1,"year":2020},{"id":9,"name":"Atin Singh","verticalid":6,"vertical":"Govt","target":"150","sap":"80","colo":"20","others":"50","quarter":1,"year":2020}]}]
, и я написал / распечатал свою таблицу следующим образом:
<table class="mat-elevation-z8 " mat-table matSort [dataSource]='targetData' (matSortChange)="sortData($event)">
<ng-container matColumnDef="Employee">
<th mat-header-cell *matHeaderCellDef mat-sort-header> Employee </th>

Я не могу напечатать еще одну строку внутри таблицы при циклическом просмотре мои данные
Окончательный результат должен быть таким, как показано ниже.
