column-bootstrap 中间的垂直对齐按钮

Question

我正在使用引导程序并尝试垂直对齐列中的按钮。

注意：我不能使用 flex，也不能按照标准定义高度。

如果我使用边距，它将无法在平板电脑和移动设备中使用。

下面是我的代码：

.col-xs-2, .col-xs-6 {
   display: inline-block;
}
.col-xs-2 {
    vertical-align: middle;
     
}

<div class="container">
    <div class="row">
    <div class="col-xs-4">
             <h4>Some really large label that will wrap to multiple lines in small screens</h4>

        </div>
    <div class="col-xs-6">
             <h4>Some really large label that will wrap to multiple lines in small screens</h4>

        </div>
        <div class="col-xs-2">
            <button class="btn" style="color: #660066;"> <i class="fa fa-arrow-left" data-ng-click="onClickBack()"></i>

            </button>
        </div><!-- 
     -->
    </div>
</div>

所以我的问题是如何使 箭头按钮 对齐到行的中间。
我试过了：display:table-cell 和 display: inline-block; 似乎没有任何效果。我错过了什么吗？
