Question

在boostrap 4中，可以有按钮组。

水平线：

<div class="btn-group" role="group" aria-label="Basic example">
  <button type="button" class="btn btn-secondary">Left</button>
  <button type="button" class="btn btn-secondary">Middle</button>
  <button type="button" class="btn btn-secondary">Right</button>
</div>

和垂直，使用班级btn-group-vertical。

是否有可能以一种很好的方式获得 3x3按钮阵列，例如在数字键盘中？

您可以将btn-group嵌套在btn-group vertical中，并使用实用程序类调整边框...

<div class="btn-group-vertical" role="group">
    <div class="btn-group">
        <button type="button" class="btn btn-secondary border-bottom-0 rounded-0">1</button>
        <button type="button" class="btn btn-secondary border-bottom-0">2</button>
        <button type="button" class="btn btn-secondary border-bottom-0 rounded-0">3</button>
    </div>
    <div class="btn-group">
        <button type="button" class="btn btn-secondary border-bottom-0 rounded-0">4</button>
        <button type="button" class="btn btn-secondary border-bottom-0">5</button>
        <button type="button" class="btn btn-secondary border-bottom-0 rounded-0">6</button>
    </div>
    <div class="btn-group">
        <button type="button" class="btn btn-secondary rounded-0">7</button>
        <button type="button" class="btn btn-secondary">8</button>
        <button type="button" class="btn btn-secondary rounded-0">9</button>
    </div>
</div>
