Что ж, решение проблемы до сих пор не добавлено в репозиторий PrimeNG, и поэтому даже последний пакет не решает его.
В настоящее время используйте решение, упомянутое в вопросе под Редактировать
Чтобы ответить на вопрос, который я задал в Редактировать , проверьте ниже:
// In some service file:
import { Table, TableHeaderCheckbox } from 'primeng/table';
@Injectable()
export class BulkSelectAllPagesService {
overridePrimeNGTableMethods() {
TableHeaderCheckbox.prototype.updateCheckedState = function () {
const currentRows = map(this.dt.value, this.dt.dataKey);
const selectedRows = map(this.dt.selection, this.dt.dataKey);
this.rowsPerPageValue = this.dt.rows;
const commonRows = intersection(currentRows, selectedRows);
return commonRows.length === currentRows.length;
};
Table.prototype.toggleRowsWithCheckbox = function (event, check) {
let _selection;
if (!check) {
_selection = this.value.slice();
each(_selection, (row) => {
const match = {}; match[this.dataKey] = row[this.dataKey];
remove(this._selection, match);
});
} else {
_selection = check ? this.filteredValue ? this.filteredValue.slice() : this.value.slice() : [];
each(this._selection, (row) => {
const match = {}; match[this.dataKey] = row[this.dataKey];
remove(_selection, match);
});
this._selection = this._selection.concat(_selection);
}
this.preventSelectionSetterPropagation = true;
this.updateSelectionKeys();
this.selectionChange.emit(this._selection);
this.tableService.onSelectionChange();
this.onHeaderCheckboxToggle.emit({
originalEvent: event,
affectedRows: _selection,
checked: check
});
};
}
// In app.component.ts
import { Component, OnInit } from '@angular/core';
import { BulkSelectAllPagesService } from 'PATH_TO_THE_FILE/bulk-select-all-pages.service';
@Component({
selector: 'app-root',
templateUrl: './app.component.html'
})
export class AppComponent implements OnInit {
constructor(
private bulkSelectAllPagesService: BulkSelectAllPagesService) {
}
ngOnInit() {
this.bulkSelectAllPagesService.overridePrimeNGTableMethods();
}
}
Конечно, необходимо включить файл службы вproviders[] в app.module.ts
Создаст блик стека и добавит позже.
Улучшенная версия для обработки данных, сгруппированных по строкам строк:
overridePrimeNGTableMethods() {
TableHeaderCheckbox.prototype.updateCheckedState = function () {

this.rowsPerPageValue = this.dt.rows;

return false;
