为了方便编写，直接在组件内声明的片段会成为该组件的 props。让我们把 header 和 row 片段移到 <FilteredList> 内部：
App
<FilteredList
data={colors}
field="name"
{header}
{row}
>
{#snippet header()}...{/snippet}
{#snippet row(d)}...{/snippet}
</FilteredList>
{#snippet header()}...{/snippet}
{#snippet row(d)}...{/snippet}现在我们可以从显式 props 中移除它们：
App
<FilteredList data={colors} field="name" {header} {row}>
{#snippet header()}...{/snippet}
{#snippet row(d)}...{/snippet}
</FilteredList>组件内部不属于已声明片段的任何内容都会成为一个特殊的 children 片段。由于 header 没有参数，我们可以通过移除块标签将其转换为 children...
App
{#snippet header()}
<header>
<span class="color"></span>
<span class="name">name</span>
<span class="hex">hex</span>
<span class="rgb">rgb</span>
<span class="hsl">hsl</span>
</header>
{/snippet}...并在另一端将 header prop 重命名为 children：
FilteredList
<script>
let { data, field, children, row } = $props();
// ...
</script><script lang="ts">
let { data, field, children, row } = $props();
// ...
</script>FilteredList
<div class="header">
{@render children()}
</div>上一页 下一页
