回答by Aravind
In your ng-template for the expansion of row use the below code
在用于行扩展的 ng-template 中，使用以下代码
<ng-template let-i="rowIndex">
<button (click)="expand(i)"> expand </button>
</ng-template>
In the button that is clicked during expansion use the below code to get the rowindex
在扩展期间单击的按钮中，使用以下代码获取行索引
expand(i){
//... your logic to expand the row...
this.expandedRowIndex = i;
}
<p-dataTable [value]="services" [paginator]="true" expandableRows="true" rowExpandMode="single" (onRowExpand)="onRowExpand($event)">
Update 1:
As you are clicking the entire row to be expanded. You can use the onRowExpandproperty of the <p-datatable>to achieve this.
更新 1：当您单击要展开的整行时。您可以使用 的onRowExpand属性<p-datatable>来实现这一点。
onRowExpand(cc){
console.log(cc)
//logs the entire object which is clicked
}
This method is triggered when the row is expanded
该方法在行展开时触发

{{rowIndex + 1}}
