<table class="table table-striped table-hover table-responsive">
  <thead>
    <th scope="col">column1</th>
    <th scope="col">column2</th>
    <th scope="col">column3</th>
  </thead>
  <tbody>
    <tr>
      <td>item1</td>
      <td>item2</td>
      <td>item3</td>
    </tr>
    <tr>
      <td>item1</td>
      <td>item2</td>
      <td>item3</td>
    </tr>
  </tbody>
</table>

是否可以在不为表格指定 100% 以外的宽度的情况下将该表格居中？我为此找到的大多数答案都使表格的宽度小于 100%。这不是很好，因为如果显示足够大，那么当您将元素居中时，表格仍然看起来没有居中。

Answer 1

您必须将您的表格放在一个带有table-responsive 类的 div 中，如下所示，

<div class="table-responsive">
<table class="table table-striped table-hover">
  <thead>
    <th scope="col">column1</th>
    <th scope="col">column2</th>
    <th scope="col">column3</th>
  </thead>
  <tbody>
    <tr>
      <td>item1</td>
      <td>item2</td>
      <td>item3</td>
    </tr>
    <tr>
      <td>item1</td>
      <td>item2</td>
      <td>item3</td>
    </tr>
  </tbody>
</table>
</div>

更新： 要使宽度不是 100% 的表格居中，请执行上述操作，并为您的 .table 类提供以下样式。

{
   width:auto;
   margin:0 auto;
}

使用mx-auto w-auto 水平居中。另外，表格应该在table-responsive...

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js"></script>

<div class="table-responsive">
    <table class="table table-striped table-hover mx-auto w-auto">
        <thead>
            <tr>
                <th scope="col">column1</th>
                <th scope="col">column2</th>
                <th scope="col">column3</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td>item1</td>
                <td>item2</td>
                <td>item3</td>
            </tr>
            <tr>
                <td>item1</td>
                <td>item2</td>
                <td>item3</td>
            </tr>
        </tbody>
    </table>
</div>

希望这可行：

 <div class="container  table-responsive">   
        <table class="table table-striped table-hover ">
            <thead>
              <th scope="col">column1</th>
              <th scope="col">column2</th>
              <th scope="col">column3</th>
            </thead>
            <tbody>
              <tr>
                <td>item1</td>
                <td>item2</td>
                <td>item3</td>
              </tr>
              <tr>
                <td>item1</td>
                <td>item2</td>
                <td>item3</td>
              </tr>
            </tbody>
        </table>
  </div>

直接从bootstrap 网站试用此代码示例。

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js"></script>

<table class="table text-center">
  <thead>
    <tr>
      <th scope="col">column1</th>
      <th scope="col">column2</th>
      <th scope="col">column3</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>item1</td>
      <td>item2</td>
      <td>item3</td>
    </tr>
    <tr>
      <td>item1</td>
      <td>item2</td>
      <td>item3</td>
    </tr>
  </tbody>
</table>
