                    {{customer[col.field]}}

app.component.ts

import { Component } from '@angular/core';
import { CustomerService } from './customerservice';
import { Customer } from './customer';
import { FilterUtils } from 'primeng/utils';
import { LazyLoadEvent } from 'primeng/api';
import { SelectItem } from 'primeng/api';
import { MessageService } from 'primeng/api';

@Component({
  selector: 'app-root',templateUrl: './app.component.html',providers: [MessageService]
})
export class AppComponent {
  customers: Customer[];
  scrollableCols: any[];
  frozenCols: any[];

  constructor(private customerService: CustomerService) {}

  ngOnInit() {
    this.customerService.getCustomersLarge().then(data => {

      this.frozenCols = [{ field: 'name',header: 'Name' }]; // assume this column will come from database

      this.customers = data;

      this.scrollableCols = [
        { field: 'id',header: 'Id' },{ field: 'date',header: 'Date' },{ field: 'company',header: 'Company' },{ field: 'status',header: 'Status' },{ field: 'activity',header: 'Activity' }
      ]; // assume this column will come from database
    });
  }
}

OUTPUT : Frozen column 和 unfrozen column 不在同一行显示。
