我正在尝试在1行中显示3列

<div class="container">
  <div class="column">Column 1</div>
  <div class="column">Column 2</div>
  <div class="column">Column 3</div>
</div>

.container {
  display: flex;
}

.column {
  flex: 1;
}

<div class="container">
  <div class="column">Column 1</div>
  <div class="column">Column 2</div>
  <div class="column">Column 3</div>
</div>

.container {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
}

.column {
  /* 可以添加样式来设置列的宽度、间距等 */
}
