Bootstrap4中如何防止table超出卡体宽度？

Question

这是我的代码示例：

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">

<div class="row">
  <div class="col-6">
    <div class="card mt-4">
      <div class="card-header">
        <h5 class="text-center">Comments</h5>
      </div>
      <div class="card-body">
        <table class="table table-primary">
          <thead>
            <tr>
              <th colspan="6">
                <div class="pull-left">
                  <button type="button" class="btn btn-outline-secondary btn-sm"><i class="fa fa-plus-circle" aria-hidden="true"></i> Add New</button>
                </div>
                <div class="pull-right">
                  <button type="button" class="btn btn-outline-secondary btn-sm"><i class="fa fa-list" aria-hidden="true"></i> View All</button>
                </div>
              </th>
            </tr>
            <tr>
              <th>Subject</th>
              <th>Author</th>
              <th>Date</th>
              <th>Year</th>
              <th>Edit</th>
              <th>Delete</th>
            </tr>
          </thead>
          <tbody>
            <tr>

              <td>This is a test comment</td>
              <td>John Wick</td>
              <td>06/28/2019</td>
              <td>2019</td>
              <td class="text-center">
                <button type="button" class="btn btn-outline-secondary btn-sm comment-edit">Edit</button>
              </td>
              <td class="text-center">
                <button type="button" class="btn btn-outline-secondary btn-sm comment-delete">Delete</button>
              </td>
            </tr>
          </tbody>
        </table>
      </div>
    </div>
  </div>
</div>

正如你在我的例子中看到的那样table溢出了卡体。有没有办法把table放到卡体里面？谢谢。

Answer 1

Bootstrap 有一个 class .table-responsive，您可以使用它来获得响应 table。如果需要，它将添加水平滚动。

<div class="table-responsive">
    <table class="table">
    ...
    </table>
</div>

旁注 - 使用最新版本的 bootstrap 和 jQuery，因为旧版本可能有错误。

您可以在 table

上使用 .table-responsive 而不是 .table
