Property 'value' does not exist on type Element

Question

I am trying to sum up the values entered in the mat-table column using an input.

I have created a table with 3 columns: Account Id, A

Answer 1

try this in your ngOnInit function. You need dynamically create the value property.

ngOnInit(){
  this.accdetailservice.accountdetails().subscribe(data =>
  let tempObject = data.map(obj => ({...obj, value: 0}));
  this.dataSource1.data = tempObject;
  );
 }
