Question

所以我有一个简单的表格一直在搞乱：

<div class="container">
    <form name="form" method="post">

    <div class="form-row mt-5">
        <div class="col-3">
            <label class="sr-only form-control-label required" for="form_column_name">Column Name</label>
            <select id="form_column_name" name="form[column_name]" class="form-control-lg form-control"><option value="Field 1" selected="selected">Field 1</option><option value="Field 2">Field 2</option></select>
        </div>
        <div class="col-8">
            <label class="sr-only form-control-label required" for="form_column_value">Column Value</label>
            <input type="text" id="form_column_value" name="form[column_value]" required="required" class="form-control-lg form-control" placeholder="Query" />
        </div>
        <div class="col-1">
            <button class="btn btn-primary btn-lg" type="button">Search</button>
        </div>
    </div>
    <div class="row mt-3">
        <div class="col-12">
            <div class="progress" style="height: 25px;">
                <div class="progress-bar progress-bar-striped progress-bar-animated" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: 100%"></div>
            </div>
        </div>
    </div>
    <div class="row mt-3">
        <div class="col-12">
            <table class="table" width="101%">
                <thead class="thead-light">
                <tr>
                    <th scope="col">#</th>
                    <th scope="col">First Name</th>
                    <th scope="col">Last Name</th>
                    <th scope="col">Username</th>
                </tr>
                </thead>
                <tbody>

                </tbody>
            </table>
        </div>
    </div>
    <input type="hidden" id="form__token" name="form[_token]" value="n0n-XzlZGwNC4-GUi8PiM5UYC25lSx_vMg7qwI7OPSg" />
</form>
</div>

这是一个Symfony 3 Twig模板，看起来像这样：

如您所见，即使一切都在col-12 ，输入的长度也仅比其他元素略长。

有谁知道如何解决这一问题？ 我可以将进度条设置为width: 101% ，但是我不知道如何更改表格。 另外，它感觉有些怪异，所以我想知道是否有更好的解决方案。

此外，使用container-fluid会使大小差异发生变化：

所以我假设我将form设置错误。 我尝试过使用form-inline ，但是也无法获得页边距并居中地以这种方式工作。

看来您需要重置按钮上的填充并为其设置宽度：

<button class="btn btn-primary btn-lg pr-0 pl-0 w-100" type="button">Search</button>

您还可以添加响应式类，以便为按钮文本留出空间：

<div class="col-lg-8 col-sm-7"> 

<div class="col-lg-1 col-sm-2">

 <link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-beta/css/bootstrap.min.css" rel="stylesheet"/> <div class="container"> <form name="form" method="post" class="m-0"> <div class="form-row mt-5"> <div class="col-3"> <label class="sr-only form-control-label required" for="form_column_name">Column Name</label> <select id="form_column_name" name="form[column_name]" class="form-control-lg form-control"><option value="Field 1" selected="selected">Field 1</option><option value="Field 2">Field 2</option></select> </div> <div class="col-lg-8 col-sm-7"> <label class="sr-only form-control-label required" for="form_column_value">Column Value</label> <input type="text" id="form_column_value" name="form[column_value]" required="required" class="form-control-lg form-control" placeholder="Query" /> </div> <div class="col-lg-1 col-sm-2" style="flex-shrink:1"> <button class="btn btn-primary btn-lg pr-0 pl-0 w-100" type="button">Search</button> </div> </div> <div class="row mt-3"> <div class="col-12"> <div class="progress" style="height: 25px;"> <div class="progress-bar progress-bar-striped progress-bar-animated" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: 100%"></div> </div> </div> </div> <div class="row mt-3"> <div class="col-12"> <table class="table" width="101%"> <thead class="thead-light"> <tr> <th scope="col">#</th> <th scope="col">First Name</th> <th scope="col">Last Name</th> <th scope="col">Username</th> </tr> </thead> <tbody> </tbody> </table> </div> </div> <input type="hidden" id="form__token" name="form[_token]" value="n0n-XzlZGwNC4-GUi8PiM5UYC25lSx_vMg7qwI7OPSg" /> </form> </div>
