Corrige l'en-tête du tableau lors du défilement

J'utilise Bootstrap V4 alpha 6 avec Angular 5 pour créer un tableau avec un en-tête fixe lors du défilement. Cependant, je n'arrive pas à le faire fonctionner.

Remarque: La navbar est fixed-top

Choses que j'ai essayées:

1) Ajoutez fixed-top class à thead.

2) 

thead {
  position: sticky;
  top: 0;
}

3) 

thead {
  display:block;
}

4) Beaucoup de CSS mais rien ne fonctionne car la table est réactive et peut défiler et il y a plusieurs lignes d’en-tête.

Qu'est-ce que je fais mal?

<nav class="navbar navbar-toggleable-md navbar-inverse fixed-top bg-inverse">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse"
    data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false"
    aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">
<img src="./assets/logo.png" width="200" height="40" class="d-inline-block align-top" alt="">
</a>
</nav>
<table class="table table-responsive w-100 d-block d-md-table table-bordered table-striped table-fixed">
<thead class="sticky-top">
<tr>
  <th colspan="16" class="text-center">PROJECT 1</th>
</tr>
<tr>
  <th rowspan="2">WON</th>
  <th rowspan="2">LST #</th>
  <th rowspan="2">FLR #</th>
  <th colspan="3">GLS</th>
  <th colspan="7">FRMS</th>
  <th rowspan="2">Scheduled Date</th>
  <th rowspan="2">Cmplt Date</th>
</tr>
<tr>
  <th>G Reqd</th>
  <th colspan="2">G Rcvd (%)</th>
  <th>Frms Reqd</th>
  <th colspan="2">Frms Ass (%)</th>
  <th colspan="2">Frms Line (%)</th>
  <th colspan="2">Frms Cmplt (%)</th>
</tr>
</thead>

<tbody>
<tr *ngFor="let project of projectData">
  <td>{{project.ordernumber}}</td>
  <td>{{project.ListNumber}}</td>
  <td>{{project.floorID}}</td>
    <td>{{project.glassRequired}}</td>
    <td>{{project.glassReceived}}</td>
    <td>{{project.glassReceivedPercent}}</td>
  <td>{{project.framesRequired}}</td>
  <td>{{project.framesAssembled}}</td>
  <td>{{project.framesAssembledPercent}}%</td>
  <td>{{project.framesGlazed}}</td>
  <td>{{project.framesGlazedPercent}}%</td>
  <td>{{project.framesShipped}}</td>
  <td>{{project.framesShippedPercent}}%</td>
  <td>{{project.deliverydate}}</td>
 <td>Not Shipped Yet</td>
</tr>
</tbody>
</table>

J'ai également créé un plnkr .

Pour ce faire, le moyen le plus simple consiste à créer votre propre fonction JavaScript pour manipuler le comportement de la manière requise. Jouez avec le code d'extrait suivant pour répondre à vos attentes.

document.onscroll = function() {
  var scroll = $(window).scrollTop();
  if (scroll >= 50) {
    $("thead").css({
      "position": "fixed",
      "top": "0px"
    });
    $("th").css({"padding":"15px 66px", "margin":"auto"});
  } else {
    $("thead").css({
      "position": "relative",
      "top": "0px"
    });
  }
};
