Bootstrap 4 Table Column Width Example

<!-- The container width must be set -->
<div class="col-md-12">
    <!-- Migrating from bootstrap 3 "table-responsive" could cause display issues -->
    <table class="table table-responsive table-striped table-hover table-sm">
        <!-- set the columns in the head to avoid repeated code in the rows -->
        <thead>
        <!-- the tr must be set to row and optionally width depending on your needs -->
            <tr class="row col-xs-12">
                <!-- Now you can set the column widths -->
                <th class="col-xs-9">Location</th>
                <th class="col-xs-3">Actions</th>
            </tr>
        </thead>
        <tbody>
            <!-- In some cases I have also had to set the column rows -->
            <tr class="row col-xs-12">
                <td class="col-xs-9">...</td>
                <td class="col-xs-9">...</td>
            </tr>
        </tbody>
    </table>
</div>
