如何在Angular2中使用带有标记的formControl

Question

我正在尝试在table元素中添加formControl，但我总是得到  error:No value accessor for form control with name: 'sender'。我尝试使用formControl或formControlName，但没有成功。我说几个aritcles，它说使用formControl没有标签，但它没有成功

有我的代码：

      <form [formGroup]="toolsubmitform">
      <div class="row">
            <div class="col-xl-4 col-lg-5">
              <md-card class="user-card">
              <!-- <md-card-header>
                <img class="rounded-circle img-user" width="70" height="70" src="assets/img/SB-admin.png">
              </md-card-header> -->
                <md-card-title class="user-title">Stuff</md-card-title>
                <md-card-content>
                  <img class="rounded-circle img-user" width="100" height="100" src="assets/img/SB-admin.png">
                  <table class="table table-bordered">
                              <thead class="table-head">
                                  <tr>
                                      <th>staff Name</th>
                                  </tr>
                              </thead>
                              <tbody>
                                  <tr >
                                      <td><span formControlName='sender'>Jason</span></td>
                                      <td></td>
                                  </tr>
                              </tbody>
                          </table>
                </md-card-content>
            </md-card>
            </div>
         </form>

这是我的组件：

import { Component, OnInit,HostListener,NgModule } from '@angular/core';
import {FormGroup, FormControl, Validators,FormArray,FormBuilder} from '@angular/forms';
import {HomepageService} from './homepage.services';
import {ToolUsing, Tool,Tooldetail} from './homepage.interface';

this.toolsubmitform=new FormGroup({
      'sender':new FormControl(),
      'operator':new FormControl(),
       tool:new FormArray([
        //  this.initTool(),
       ]),
    })

这是我的angular2版本：

"@angular/common": "^2.3.1",
    "@angular/compiler": "^2.3.1",
    "@angular/core": "^2.3.1",
    "@angular/forms": "^2.3.1",
