Remove the angular2 component's selector tag

I have a user component for 2 templates. First template for users table, second one for a user page. I select which template to use by role attribute.

First example of using:

<table>
    <tr user *ngFor="let user of users" [user]="user" role="UserTableItem"></tr>
</table>

In another one template I use my component like this:

<div user [user]="user" role="UserCard"></div>

So, my user component template:

// user.template.html

<user-card [user]="user" *ngIf="role === 'UserCard'"></user-card>
<user-list-item [user]="user" *ngIf="role === 'UserListItem'"></user-list-item>

As we can see, here two components user-card and user-list-item. user-card contains div blocks, user-list-item contains td blocks. And table crashed because I have a <user-list-item> block inside and my table looks like:

<table>
   <tr>
     <user-list-item>
       <td></td>
       <td></td>
     </user-list-item>
   </tr>
</table>

How can I solve my problem and get table like this?

<table>
   <tr>
     <td></td>
     <td></td>
   </tr>
</table>

UPD:

My user component:

// user.component.ts

import { Component, Input, Inject, Attribute } from '@angular/core';
import { UserCard } from './userCard.component';
import { UserListItem } from './userListItem.component';

@Component({
  selector: '[user]',
  templateUrl: './user.template.html',
  directives: [UserCard, UserListItem]
})
export class User {
  @Input() user:any = null;
  role:string;

  constructor(
    @Attribute('role') role) {
    this.role = role;
  }
}

userListItem.template.html:

<td>
    {{user.id}}
</td>

<td>
    <img src="{{user.avatarUrl160}}" alt="User profile picture" width="160">
</td>
// ...

userCard.template.html:

<div class="card card-block" *ngIf="user">
    <h4 class="card-title">
        User #{{user.id}}
        <span class="tag tag-success" *ngIf="!user.isBanned">Active</span>
        <span class="tag tag-danger" *ngIf="user.isBanned">Banned</span>
        <span class="tag tag-danger" *ngIf="user.isDeleted">Deleted</span>
    </h4>
    <p>
        <img width="340" src="{{user.avatarUrl160}}">
    // ...
</div>

<div class="card card-block" *ngIf="user">
    <span class="text-muted">Company: </span> {{user.company.name}}<br>
    <span class="text-muted">Company logo: </span>
    // ...

I find your question a bit confusing but I guess what you want is an attribute selector

@Component({
  selector: '[user-list-item]',
  ...
})
export class UserListItem { ... }

and instead of

<user-card [user]="user" *ngIf="role === 'UserCard'"></user-card>
<user-list-item [user]="user" *ngIf="role === 'UserListItem'"></user-list-item>

use

<td user-card [user]="user" *ngIf="role === 'UserCard'"></td>
<td user-list-item [user]="user" *ngIf="role === 'UserListItem'"></td>
