Bootstrap table won't fill container width

Ensuring table responsiveness

Nobody, especially your users, like things that don't adapt and respond well to changes. Like a social chameleon, Bootstrap provides a .table-responsive utility class to wrap your table. It allows horizontal scrolling on small screens (<768px), keeping everything neat!

<div class="table-responsive">
  <table class="table w-100">
    <!-- Insert life-changing code here -->
  </table>
</div>


You got it, buddy! Just wrap, scroll and see the magic happening across various devices.

Debugging common issues

Even the most experienced mechs have to pop open the hood and check their gears. If you're not getting that full-width table, here's your troubleshooting checklist:

• Face-off with any rogue CSS styles that might be overriding the Bootstrap classes. Beware of the dark side!
• Make sure your table's <thead> and <tbody> formatting is in check. It's not rocket science, but it sure is important.
• Check for <th> and <td> tags playing hide and seek within your rows.
• Double-check your Bootstrap version. If you're using Bootstrap 4, .w-100 might not work if you're stuck in the past with Bootstrap 3.3.2.

Bootstrap version compatibility

Variables like different Bootstrap versions can play sorry tricks on your code. Cross-check your example with official docs to ensure you’re following correct semantics for your version.

Expanding layout control

For those with an insatiable hunger for control and flexibility, consider the Bootstrap grid system. Bury your table within the depths of grid columns for a dynamically resizable table:

<div class="container">
  <div class="row">
    <div class="col-12">
      <div class="table-responsive">
        <table class="table w-100">
          <!-- Insert more awesome code here -->
        </table>
      </div>
    </div>
  </div>
</div>


Control. Power. Responsiveness. Yep, it's the cool kids' table now.

Fluid design considerations

Suppressing horizontal scroll

Who needs horizontal scrolls when you can have a fluid container? Wrap your table with .container-fluid instead of .container to adjust to the viewport’s full width:

<div class="container-fluid">
  <table class="table w-100">
    <!-- Insert code as if you’re F. Scott Fitzgerald -->
  </table>
</div>


Adapting column sizing

For columns to fit their content, utilize auto layout classes. Let the content determine the width:

<table class="table w-100">
  <colgroup>
    <col class="col-auto">
    <col class="col">
    <col class="col-auto">
  </colgroup>
  <!-- Lines of labyrinthine lore go here -->
</table>


Maximizing utility classes

Bootstrap's utility classes like .d-block and .d-md-table can be your knights in shining armor. They toggle layouts across devices:

<table class="table w-100 d-block d-md-table">
  <!-- Insert most thought-provoking code here -->
</table>


Now your table behaves like a block element on small screens, and properly as a table on medium-sized screens and up.
