if you want to get an only once sort change event,
change the binding nzSortOrderChange event handler from <th> to <thead>
and add [nzColumnKey]="column.name" in <th> it will work, is this solve your issue?

      <thead (nzSortOrderChange)="orderChange($event)">
        <tr>
          <th
            *ngFor="let column of listOfColumns"
            [nzSortOrder]="column.sortOrder"
            ...
            [nzColumnKey]="column.name"
          >
            {{ column.name }}
          </th>
        </tr>
      </thead>

I think the API doc should be updated.

SortChange API property changed from
nzSortChange(8.5) ->
nzSortOrderChange(9.0 later)

but the API doc start missing thead block for no reason but existed in 8.5 API doc (with property: nzSortChange),
and EventEmitter:nzSortOrderChange still exists in <th> and<thead> from 9.0 to current(11.4),

current doc, 8.5 doc
