更新

到目前为止，我来到这个代码，没有效果。

从Bootstrap获取的CSS 2.3.2：

.table-bordered
{
    -webkit-border-radius: 4px;
    -moz-border-radius: 4px;
    border-radius: 4px;
}
 
.table-bordered thead:first-child tr:first-child > th:first-child,.table-bordered tbody:first-child tr:first-child > td:first-child,.table-bordered tbody:first-child tr:first-child > th:first-child
{
    -webkit-border-top-left-radius: 4px;
    border-top-left-radius: 4px;
    -moz-border-radius-topleft: 4px;
}
 
.table-bordered thead:last-child tr:last-child > th:first-child,.table-bordered tbody:last-child tr:last-child > td:first-child,.table-bordered tbody:last-child tr:last-child > th:first-child,.table-bordered tfoot:last-child tr:last-child > td:first-child,.table-bordered tfoot:last-child tr:last-child > th:first-child
{
    -webkit-border-bottom-left-radius: 4px;
    border-bottom-left-radius: 4px;
    -moz-border-radius-bottomleft: 4px;
}

HTML代码：

<table class="table table-hover table-responsive table-bordered">
    <thead>
        <tr>
            <th style="width: 50%">
                Config. Name
            </th>
            <th>
                API Calls
            </th>
            <th>
                Current Amount
            </th>
            <th>
                Actions
            </th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>
                <a href="/searchsources/details">Agennda</a>
            </td>
            <td>
                2,876
            </td>
            <td>
                $ 80.67
            </td>
            <td>
                <a href="/searchsources/details">Edit</a>
            </td>
        </tr>
    </tbody>
