由于代码片段（如函数）只是值，因此可以将它们作为 props 传递给组件。
¥Since snippets — like functions — are just values, they can be passed to components as props.
使用这个 <FilteredList> 组件。它的工作是过滤传递给它的 data，但它对如何渲染数据没有任何意见 - 这是父组件的责任。
¥Take this <FilteredList> component. Its job is to filter the data that gets passed into it, but it has no opinions about how that data should be rendered — that’s the responsibility of the parent component.
我们已经定义了一些代码片段。首先将它们传递到 <FilteredList>：
¥We’ve already got some snippets defined. Begin by passing them into the <FilteredList>:
<FilteredList
data={colors}
field="name"
{header}
{row}
></FilteredList>然后，在另一边，将 header 和 row 声明为 props：
¥Then, on the other side, declare header and row as props:
<script>
let { data, field, header, row } = $props();
// ...
</script><script lang="ts">
let { data, field, header, row } = $props();
// ...
</script>最后，用渲染标签替换占位符内容：
¥Finally, replace the placeholder content with render tags:
<div class="header">
{@render header()}
</div>
<div class="content">
{#each filtered as d}
{@render row(d)}
{/each}
</div>你再也不必记住 MistyRose 或 PeachPuff 的十六进制代码了。
¥Never again will you have to memorize the hex code for MistyRose or PeachPuff.
<script>
import FilteredList from './FilteredList.svelte';
import { colors } from './data.js';</script>
