*ngFor 在 ng-template 上不输出任何 Angular2

Question

Not sure why my *ngFor loop is printing nothing out. I have the following code in an html file:

<table class="table table-hover">
    <thead>
        <tr>
            <th>Name</th>
            <th>Email</th>
            <th>Company</th>
            <th>Status</th>
        </tr>
    </thead>
    <tbody>
        <!-- NGFOR ATTEMPTED HERE -- no content printed -->
        <ng-template *ngFor="let xb of tempData">
            <tr data-toggle="collapse" data-target="#demo1" class="accordion-toggle">
                <td>{{ xb.name }}</td>
                <td>{{ xb.email }}</td>
                <td>{{ xb.company }}</td>
                <td>{{ xb.status }}</td>
            </tr>
            <!-- other content -->
        </ng-template>
    </tbody>
</table>

Then, in my simple component I have the following:

import { Component }        from '@angular/core';

@Component({
    selector: 'my-profile-exhibitors',
    templateUrl: './profile-exhibitors.component.html',
    styleUrls: ['./profile-exhibitors.component.scss']
})
export class ProfileExhibitorsComponent {
    public tempData: any = [
        {
            'name': 'name1',
            'email': 'email1@gmail',
            'company': 'company',
            'status': 'Complete'
        },
        {
            'name': 'name2',
            'email': 'email2@gmail',
            'company': 'company',
            'status': 'Incomplete'
        }
    ];
    constructor() {}
}

When I run this code, I get zero output. Even weirder is that when I select the element using debug tools I see this:

Looks like it correctly recognizes my object, but then outputs nothing.

Answer 1

I think what you want is

<ng-container *ngFor="let xb of tempData">

or

<ng-template ngFor let-xb [ngForOf]="tempData">

Answer 2

获取索引： <ng-template ngFor let-xb [ngForOf]="tempData" let-index="index">
