Using ngIf without an extra element in Angular 2

Can I use ngIf without an extra container element?

<tr *ngFor="...">
  <div *ngIf="...">
    ...
  </div>
  <div *ngIf="!...">
    ...
  </div>
</tr>

It doesn't work in a table because that would make invalid HTML.

ng-container is preferred over template:

<ng-container *ngIf="expression">

See:

Angular 2 ng-container

I found a method for that on: https://angular.io/docs/ts/latest/guide/template-syntax.html#!#star-template.

You can simply use the <template> tag and replace *ngIf with [ngIf] like this.

<template [ngIf]="...">
  ...
</template>

You can't put div directly inside tr, that would make invalid HTML. tr can only have td/th/table element in it & inside them you could have other HTML elements.

You could slightly change your HTML to have *ngFor over tbody & have ngIf over tr itself like below.

<tbody *ngFor="...">
  <tr *ngIf="...">
    ...
  </tr>
  <tr  *ngIf="!...">
    ...
  </tr>
  ..
</tbody>
