angular/table-tbody

Dlaczego

When the server sends <table><tr>, the browser's parser adds a <tbody> the template does not know about. During hydration Angular finds a different DOM than it rendered and reports a mismatch; the component is then rendered again on the client, which costs time and can flash or shift the table.

Poprawka

Wrap rows in <tbody> (and header rows in <thead>) in the template itself. It is valid HTML either way and also keeps the table structure clear for assistive technology.

Przykłady

<table>
  @for (order of orders(); track order.id) { <tr><td>{{ order.number }}</td></tr> }
</table>
<!-- good -->

  </tbody>
