官网代码演示：

<template>
  <a-timeline>
    <a-timeline-item color="green">
      Create a services site 2015-09-01
    </a-timeline-item>
    <a-timeline-item color="green">
      Create a services site 2015-09-01
    </a-timeline-item>
    <a-timeline-item color="red">
      <p>Solve initial network problems 1</p>
      <p>Solve initial network problems 2</p>
      <p>Solve initial network problems 3 2015-09-01</p>
    </a-timeline-item>
    <a-timeline-item>
      <p>Technical testing 1</p>
      <p>Technical testing 2</p>
      <p>Technical testing 3 2015-09-01</p>
    </a-timeline-item>
    <a-timeline-item color="gray">
      <p>Technical testing 1</p>
      <p>Technical testing 2</p>
      <p>Technical testing 3 2015-09-01</p>
    </a-timeline-item>
    <a-timeline-item color="gray">
      <p>Technical testing 1</p>
      <p>Technical testing 2</p>
      <p>Technical testing 3 2015-09-01</p>
    </a-timeline-item>
  </a-timeline>
</template>

将代码copy到项目中只显示文本内容，不显示时间轴

需要引入依赖，且将标签修改为 timeline 和 timeline-item

<template>
        <timeline-item color="green">
          Create a services site 2015-09-01
        </timeline-item>
        <timeline-item color="green">
          Create a services site 2015-09-01
        </timeline-item>
        <timeline-item color="red">
          <p>Solve initial network problems 1</p>
          <p>Solve initial network problems 2</p>
          <p>Solve initial network problems 3 2015-09-01</p>
        </timeline-item>
        <timeline-item>
          <p>Technical testing 1</p>
          <p>Technical testing 2</p>
          <p>Technical testing 3 2015-09-01</p>
        </timeline-item>
        <timeline-item color="gray">
          <p>Technical testing 1</p>
          <p>Technical testing 2</p>
          <p>Technical testing 3 2015-09-01</p>
        </timeline-item>
        <timeline-item color="gray">
          <p>Technical testing 1</p>
          <p>Technical testing 2</p>
          <p>Technical testing 3 2015-09-01</p>
        </timeline-item>
</template>
<script lang="ts" setup>
  //引入时间轴
  import { Timeline, TimelineItem } from 'ant-design-vue';
</script>
