Mat-table Sorting Demo not Working

Question

I am trying to get the mat-table sorting to work locally, and while I can get the data to show up as expected, clicking on the header row does not do the sortin

Answer 1

My solution was to fix several things (basically merging most of the solutions in this page).

Things to check:

1. BrowserModule, MatTableModule, MatSortModule Modules should be imported in the root modules file.
2. Make sure to have used MatTableDatasource class and pass your data array in it as a parameter
3. Make sure your table is not nested in an *ngIf=.... directive. Use other conditional operations instead (still don't understand why).
