Angular material table not rendering data

Question

Angular material data is not rendering the data even though datasource has correct data to be displayed

Note: Paginator is working correctly according to the datasource

HTML

TS

this.assignmentDataSource = new MatTableDataSource<Assignment>(assignmentList); //assignmentList has data loaded
this.assignmentDataSource.paginator = this.paginator;

Output

Console

console.log(this.assignmentDataSource);

I want to know why the data is not rendering to the view

Thanks !!!

this.assignmentDataSource = new MatTableDataSource<any>(Object.values(assignmentList)); — Vikas

There have matColumnDef directives, and this directive try to get the key of an object. But you define a bad key, and the dataTable cant read the objects. Try to add the excepted matColumnDef values.

Thanks @Anarno. This is where I missed. I have just created the displayedColumns variable and not defined any column names. After defining the column names, table rendering the data correctly

Try replacing tag <table></table> for <mat-table></mat-table>.
