我有以下代码:

<div class="table">
    <div class="row">
        <div class="cell">Cell</div>
        <div class="cell">Cell</div>
    </div>
    <div class="row">
        <div class="cell colspan2">Cell</div>
    </div>
</div>

<style>
    .table {
        display: table;
    }
    .row {
        display: table-row;
    }
    .cell {
        display: table-cell;
    }
    .colspan2 {
        /* What to do here? */
    }
</style>

非常直截了当.如何为元素添加colspan(或等效的colspan)display: table-cell？
