1、HTML代码

<!-- 表格 -->
  <!-- tabVal是一个数组对象，表格的数据，key就是field的名称 -->
  <p-dataTable [value]="tabVal" emptyMessage="无记录">
    <p-column field='user_name' header='用户姓名' sortable="custom" (sortFunction)="mySort($event)">
      <ng-template let-col let-row="rowData" pTemplate="body" style="width: 72px">
        <span class="nowrap" pTooltip='{{row.user_name}}' tooltipPosition="top">
            {{row.user_name}}
          </span>
      </ng-template>
    </p-column>
    <p-column field='reg_qq_number' header='QQ号码' sortable="custom" (sortFunction)="mySort($event)"></p-column>
    <p-column field='qq_name' header='QQ昵称'>
      <ng-template let-col let-row="rowData" pTemplate="body">
        <span class="nowrap" pTooltip='{{row.qq_name}}' tooltipPosition="top">
            {{row.qq_name}}
          </span>
      </ng-template>
    </p-column>
    <p-column field='orgin_fullname' header='机构全称'>
      <ng-template let-col let-row="rowData" pTemplate="body">
        <span class="nowrap" pTooltip='{{row.orgin_fullname}}' tooltipPosition="top">
            {{row.orgin_fullname}}
          </span>
      </ng-template>
    </p-column>
    <p-column field='operation' header='操作'>
      <!--
          let-col: col这个td的值对象
          let-row: row这一行tr的值对象
      -->
      <ng-template let-col let-row="rowData" pTemplate="body">
        <div class="text-center">
          <span class="fa fa-copy cursor" ngxClipboard [cbContent]="row.qq_name" (cbOnSuccess)="copyLineInfo($event)"></span>
          <span class="fa fa-edit cursor" (click)="editLineInfo(row)"></span>
        </div>
      </ng-template>
    </p-column>
    <p-column field='business_label' header='业务标签'>
      <ng-template let-col let-row="rowData" pTemplate="body">
        <span class="nowrap" pTooltip='{{row.business_label}}' tooltipPosition="top" style="width: 100px">
            {{row.business_label}}
          </span>
      </ng-template>
    </p-column>
    <p-column field='bind_number' header='代联号' [sortable]="true"></p-column>
    <p-column field='like_msg' header='欢迎信息' [sortable]="true"></p-column>
    <p-column field='user_come_from' header='用户来源' [sortable]="true"></p-column>
    <p-column field='reg_state' header='注册状态' [sortable]="true"></p-column>
    <p-column field='create_time' header='创建日期' [sortable]="true"></p-column>
  </p-dataTable>
  <p-paginator rows="30" totalRecords="100" [rowsPerPageOptions]="[10,30,50,100]" (onPageChange)="paginate($event)"></p-paginator>
</div>

2、组件中的js代码

// 表格数据
    this.tabVal = [
      {
        user_name: "zxc",reg_qq_number: "2212323232",qq_name: "爱篮球没理由",orgin_fullname: "陕西省西安市高新区招商银行支行",businessLabel: "首付款",bind_number: "232323",like_msg: "你好",user_come_from: "中国",reg_state: "已注册",create_time: "2017-7-8"
      },{
        user_name: "lzy",reg_qq_number: "1234766544",business_label: "资金，债券一级，债券二级",create_time: "2017-7-8"
      }
    ];

3、实现排序

A. 使用primeNg默认功能，只需要添加[sortable]="true"

<p-column field='bind_number' header='代联号' [sortable]="true"></p-column>

B. 添加排序方法，调用后台接口，需要如下配置 sortable="custom" (sortFunction)="mySortFun($event)",然后在mySortFun()函数中，获取参数，调用接口排序就可以了。

<p-column field='reg_qq_number' header='QQ号码' sortable="custom" (sortFunction)="mySort($event)"></p-column>
