您可以通过将单元格放置到行中来实现这一点，这些行本身使用flex-direction: column进行堆叠。

样式很粗糙，但请尝试如下所示：

​

.outer {
    display: flex;
    flex-direction: column;
}

.row {
    display: flex;
    flex-direction: row;
}

.cell {
    margin: 1.0em;
    padding: 1.0em;
    border: 1px solid black;
    flex-grow: 1;
}

<div class="outer">
    <div class="row">
        <div class="cell">Cell 1</div>
        <div class="cell">Cell 2</div>
        <div class="cell">Cell 3</div>
    </div>
    <div class="row">
        <div class="cell">Cell 3</div>
        <div class="cell">Cell 4</div>
        <div class="cell">Cell 5</div>
        <div class="cell">Cell 6</div>
    </div>
    <div class="row">
        <div class="cell">Cell 7</div>
        <div class="cell">Cell 8</div>
        <div class="cell">Cell 9</div>
    </div>
</div>
