html - 比屏幕大的 Flexbox child

Question

我试图让 flexbox 元素不会因其内容而变得比屏幕大。

这是一些基本代码:

section,
aside {
  font-size: 1.5em;
}
#container1,
#container2 {
  display: flex;
}
#overflower {
  overflow-x: auto;
}
aside {
  background-color: red;
  flex-basis: 15em;
  width: 15em;
  min-width: 15em;
  flex-grow: 0;
}
section {
  background-color: green;
  flex-grow: 1;
  flex-basis: 15em;
}

<div id="container1">
  <aside>Short text OK</aside>
  <section>Short text OK</section>
</div>
<br>
<div id="container2">
  <aside>Short text OK</aside>
  <section>
    <div id="overflower">
      <table>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
        <td>aaa</td>
      </table>
    </div>
  </section>
</div>

我也做了一个 jsfiddle 来解释它:https://jsfiddle.net/51jxxe4p/2/

左边的列有固定的宽度，右边的应该使用剩余的空间(正确的行为)。但是，如果表格太大，它会长到屏幕之外，我尽量避免这种情况。我以为 #overflower 会阻止它，但它不起作用。我尝试在各个地方将宽度设置为 100%，但也没有成功。

不要在其中添加任何溢出元素，直接将 overflow-x: auto 设置为 flex 元素。

section, aside {
  font-size: 1.5em;
}
#container1, #container2 {
  display: flex;
}
aside {
  background-color:red;
  flex-basis: 15em;
  width: 15em;
  min-width: 15em;
  flex-grow: 0;
}
section {
  background-color: green;
  flex-grow: 1;
  flex-basis: 15em;
  overflow-x: auto;
}

<div id="container1">
  <aside>Short text OK</aside>
  <section>Short text OK</section>
</div>
<br>
<div id="container2">
  <aside>Short text OK</aside>
  <section>
    <table>
      <tr>
        <td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td><td>aaa</td>
      </tr>
    </table>
  </section>
</div>

原因是 flex 元素中隐含的最小尺寸，如 Why doesn't flex item shrink past content size? 中所述。
