当.col有一个.table响应的子级时，自动布局中断

Question

使用Bootstrap的auto-layout网格时，可以显式地指定某些列的宽度，而其余列则均匀地分配剩余空间。但是，如果自动.col之一有一个.table-responsive子代，则整个系统似乎崩溃了：

<div class="container">
  <div class="row">
    <div class="col" style="height:40px;border: thick solid red">
      Row 1: auto-layout .col works fine
    </div>
    <div class="col col-3" style="height:40px;border: thick solid green">
      .col .col-3
    </div>
  </div>
  <div class="row">
    <div class="col" style="height:120px;border: thick solid red">
      Row 2: auto-layout .col > .table-responsive = broken grid
      <div class="table-responsive">
        <table class="table">
          <thead>
            <tr>
              <th style="min-width:400px">foobarbazbarfoo</th>
              <th style="min-width:400px">foobarbazbarfoo</th>
              <th style="min-width:400px">foobarbazbarfoo</th>
              <th style="min-width:400px">foobarbazbarfoo</th>
            </tr>
          </thead>
        </table>
      </div>
    </div>
    <div class="col col-3" style="height:120px;border: thick solid green">
      .col .col-3
    </div>
  </div>
</div>

如何将.table-responsive子项放置在Bootstrap的网格中没有指定显式宽度，以便其行为始终如一？或者换句话说，如何使示例中的两行看起来相同-在表后没有垂直中断。

在您的overflow: auto table-responsive div上添加parent

<div class="col" style="height:120px;border: thick solid red; overflow-x:auto">
      Row 2: auto-layout .col > .table-responsive = broken grid
