为什么 position:sticky with left:0 不能在可滚动容器内工作？

Question

我有这个问题 - 我有一个包含一些行的容器，并且在每一行中都有一个粘性左列，然后是多个其他列。现在在下面的示例中，这可以工作一段时间，但是当您滚动父容器时，位置sticky 不再起作用，并且在您滚动时它会被推动。

.container {
  overflow-x: scroll;
}

.row {
  display: flex;
  width: 100%;
  
}

.item {
  min-width: 173px;
}

.sticky {
  min-width: 250px;
  position: sticky;
  left: 0;
  background: red;
}

<div class="container">
  <div class="row">
    <div class="item sticky">STICKY ROW 1</div>
    <div class="item">1</div>
    <div class="item">2</div>
    <div class="item">3</div>
    <div class="item">4</div>
    <div class="item">5</div>
    <div class="item">6</div>
    <div class="item">7</div>
    <div class="item">8</div>
    <div class="item">9</div>
    <div class="item">10</div>
  </div>
  <div class="row">
    <div class="item sticky">STICKY ROW 2</div>
    <div class="item">1</div>
    <div class="item">2</div>
    <div class="item">3</div>
    <div class="item">4</div>
    <div class="item">5</div>
    <div class="item">6</div>
    <div class="item">7</div>
    <div class="item">8</div>
    <div class="item">9</div>
    <div class="item">10</div>
  </div>
  <div class="row">
    <div class="item sticky">STICKY ROW 3</div>
    <div class="item">1</div>
    <div class="item">2</div>
    <div class="item">3</div>
    <div class="item">4</div>
    <div class="item">5</div>
    <div class="item">6</div>
    <div class="item">7</div>
    <div class="item">8</div>
    <div class="item">9</div>
    <div class="item">10</div>
  </div>
</div>

有没有办法解决这个问题..或者有其他方法可以解决这个问题吗？？

我想要的结果是能够将粘性 div 粘贴在 0 的左侧，并让其他列在下方滚动..

现在我知道，如果 overflow-x: scroll 在实际的 .row 元素上，它会按预期工作.. 但我可能有 100 多行，所以滚动需要在父容器上

添加边框以更好地查看与使用块级元素和width:100% 的限制相关的问题（不是您设置的无用而是块元素的默认行为）

.container {
  overflow-x: scroll;
}

.row {
  display: flex;
  border:1px solid;
}

.item {
  min-width: 173px;
}

.sticky {
  min-width: 250px;
  position: sticky;
  left: 0;
  background: red;
}

<div class="container">
  <div class="row">
    <div class="item sticky">STICKY ROW 1</div>
    <div class="item">1</div>
    <div class="item">2</div>
    <div class="item">3</div>
    <div class="item">4</div>
    <div class="item">5</div>
    <div class="item">6</div>
    <div class="item">7</div>
    <div class="item">8</div>
    <div class="item">9</div>
    <div class="item">10</div>
  </div>
  <div class="row">
    <div class="item sticky">STICKY ROW 2</div>
    <div class="item">1</div>
    <div class="item">2</div>
    <div class="item">3</div>
    <div class="item">4</div>
    <div class="item">5</div>
    <div class="item">6</div>
    <div class="item">7</div>
    <div class="item">8</div>
    <div class="item">9</div>
    <div class="item">10</div>
  </div>
  <div class="row">
    <div class="item sticky">STICKY ROW 3</div>
    <div class="item">1</div>
    <div class="item">2</div>
    <div class="item">3</div>
    <div class="item">4</div>
    <div class="item">5</div>
    <div class="item">6</div>
    <div class="item">7</div>
    <div class="item">8</div>
    <div class="item">9</div>
    <div class="item">10</div>
  </div>
</div>

考虑使用inline-flex 的内联级别元素来解决问题。添加min-width:100% 以确保在内容很小的情况下至少覆盖100% 的宽度。

.container {
  overflow-x: scroll;
}

.row {
  display: inline-flex;
  min-width: 100%;
  border:1px solid;
}

.item {
  min-width: 173px;
}

.sticky {
  min-width: 250px;
  position: sticky;
  left: 0;
  background: red;
}

<div class="container">
  <div class="row">
    <div class="item sticky">STICKY ROW 1</div>
    <div class="item">1</div>
    <div class="item">2</div>
    <div class="item">3</div>
    <div class="item">4</div>
    <div class="item">5</div>
    <div class="item">6</div>
    <div class="item">7</div>
    <div class="item">8</div>
    <div class="item">9</div>
    <div class="item">10</div>
  </div>
  <div class="row">
    <div class="item sticky">STICKY ROW 2</div>
    <div class="item">1</div>
    <div class="item">2</div>
    <div class="item">3</div>
    <div class="item">4</div>
    <div class="item">5</div>
    <div class="item">6</div>
    <div class="item">7</div>
    <div class="item">8</div>
    <div class="item">9</div>
    <div class="item">10</div>
  </div>
  <div class="row">
    <div class="item sticky">STICKY ROW 3</div>
    <div class="item">1</div>
    <div class="item">2</div>
    <div class="item">3</div>
    <div class="item">4</div>
    <div class="item">5</div>
    <div class="item">6</div>
    <div class="item">7</div>
    <div class="item">8</div>
    <div class="item">9</div>
    <div class="item">10</div>
  </div>
</div>
