经过一番挖掘，我发现了一个与用户无关的注释，建议您ajax使用自己的函数覆盖该选项以处理服务器端调用。

这里的技巧是将一个空数组返回到DataTables回调，因此它不会使用其渲染器来渲染表。这将由Angular完成。为服务器指定列名称也是一个好主意。

ngOnInit(): void {
    var that = this;

    this.dtOptions = {
        pagingType: 'full_numbers',
        serverSide: true,
        processing: true,
        ajax: (dataTablesParameters: any, callback) => {
            that.http
                .post<DataTablesResponse>('/api/Persons', dataTablesParameters, {})
                .subscribe(resp => {
                    that.persons = resp.data;

                    callback({
                        recordsTotal: resp.recordsTotal,
                        recordsFiltered: resp.recordsFiltered,
                        data: [],
                    });
                });
        },
        columns: [
            { data: "id" },
            { data: "firstName" },
            { data: "lastName" },
        ],
    };
}

由于DataTables认为没有要显示的行，因此将显示“无可用数据”消息。处理它的最简单方法是用CSS隐藏它。您可以将其添加到您的全局styles.css中

.dataTables_empty {
    display: none;
}

然后在模板中自己显示：

<tr *ngIf="persons?.length == 0">
    <td colspan="3" class="no-data-available">No data!</td>
</tr>

这是完整的代码。在Angular 5.0.0，datatables.net 1.10.16和angular-datatables 5.0.0中进行了测试：

angular-way-server-side.component.ts

import { Component, OnInit } from '@angular/core';
import { HttpClient, HttpResponse } from '@angular/common/http';
import { DataTablesResponse } from '../datatables/datatables-response';
import { Person } from './person';

@Component({
    selector: 'app-angular-way-server-side',
    templateUrl: 'angular-way-server-side.component.html',
    styleUrls: ['angular-way-server-side.component.css'],
})
export class AngularWayServerSideComponent implements OnInit {
    dtOptions: DataTables.Settings = {};
    persons: Person[];

    constructor(private http: HttpClient) { }

    ngOnInit(): void {
        var that = this;

        this.dtOptions = {
            pagingType: 'full_numbers',
            serverSide: true,
            processing: true,
            ajax: (dataTablesParameters: any, callback) => {
                that.http
                    .post<DataTablesResponse>('/api/Persons', dataTablesParameters, {})
                    .subscribe(resp => {
                        that.persons = resp.data;

                        callback({
                            recordsTotal: resp.recordsTotal,
                            recordsFiltered: resp.recordsFiltered,
                            data: [],
                        });
                    });
            },
            columns: [
                { data: "id" },
                { data: "firstName" },
                { data: "lastName" },
            ],
        };
    }
}

angular-way-server-side.component.html

<table datatable [dtOptions]="dtOptions" class="row-border hover">
    <thead>
        <tr>
            <th>ID</th>
            <th>First name</th>
            <th>Last name</th>
        </tr>
    </thead>
    <tbody>
        <tr *ngFor="let person of persons">
            <td>{{ person.id }}</td>
            <td>{{ person.firstName }}</td>
            <td>{{ person.lastName }}</td>
        </tr>
        <tr *ngIf="persons?.length == 0">
            <td colspan="3" class="no-data-available">No data!</td>
        </tr>
    </tbody>
</table>

angular-way-server-side.component.css

.no-data-available {
    text-align: center;
}

人

export class Person {
    id: number;
    firstName: string;
    lastName: string;
}

数据表响应

export class DataTablesResponse {
    data: any[];
    draw: number;
    recordsFiltered: number;
    recordsTotal: number;
}

src / styles.css

.dataTables_empty {
    display: none;
}

服务器端的实现方式几乎与使用带JavaScript /
jQuery的数据表的方式相同。您可以在PHP中看到一个非常简单的示例实现。
