Navbar和THead Fixed-Top

Question

I am creating a simple site that will show a list of computers along with some of their information. So far I've got everything functioning pretty much how I want except I can't get the thead to stay fixed to the navbar while scrolling. I'm still pretty new to all this, but I'll list some of the things I've tried below along with a simplified version of my web page.

1. Putting a div around navbar/table through thead: Doesn't scroll
2. Making the tbody scrollable and fixing the position of navbar/thead: ruined formatting
3. Applying fixed position just to thead: Also ruins formatting

Any help is greatly appreciated!

Answer 1

We can use the answer provided here as a starting point with the following modification:

.table-fixed {
  width: 100%;
}

.table-fixed thead th {
    position: sticky;
    position: -webkit-sticky;
    /*top: 0;*/
    top:55px; /* the height of the fixed nav-bar */
    z-index: 999;
    background-color: #000;
    color: #fff;
}

Now remove the <br> right after the nav-bar in your HTML .

<nav class="navbar fixed-top navbar-expand-lg navbar-dark bg-dark">
  <a class="navbar-brand" href="#">Navbar</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
    </ul>
    <form class="form-inline my-2 my-lg-0">
      <input id="myInput" onkeyup="myFunction()" class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
    </form>
  </div>
</nav>
<!-- remove the br from here, we will tackle this with the top:55px -->

Answer 2

Maybe this will help you It's a fiddle based on your own.

1st) make the thead fixed with some simple check, just like the following

$(window).scroll(function() {
if ($(this).scrollTop() >= 100) { 
    $('#myTable').addClass('fixed');  
} else {
            $('#myTable').removeClass('fixed');
    }
});

2nd) Apply some css

#myTable.fixed thead { 
  position: fixed; background: #dddddd;
  left: 0; width: 100%;
}

I am not sure about which formatting is ruined, if you are talking about the th then you can style that with some css
