创建卡片组件Card.vue

其中引入使用了以下组件和工具函数：

• Vue3骨架屏（Skeleton）
• 监听插槽存在 useSlotsExist

<script setup lang="ts">
import { computed } from 'vue'
import type { CSSProperties } from 'vue'
import Skeleton from '../skeleton'
import { useSlotsExist } from '../utils'
interface Props {
  width?: number | string // 卡片宽度，单位 px
  title?: string // 卡片标题 string | slot
  extra?: string // 卡片右上角的操作区域 string | slot
  bordered?: boolean // 是否有边框
  loading?: boolean // 当卡片内容还在加载中时，可以用 loading 展示一个占位
  size?: 'default' | 'small' // 卡片的尺寸
  headStyle?: CSSProperties //    标题区域自定义样式
  bodyStyle?: CSSProperties // 内容区域自定义样式
}
const props = withDefaults(defineProps<Props>(), {
  width: 'auto',
  title: undefined,
  extra: undefined,
  bordered: true,
  loading: false,
  size: 'default',
  headStyle: () => ({}),
  bodyStyle: () => ({})
})
const cardWidth = computed(() => {
  if (typeof props.width === 'number') {
    return props.width + 'px'
  }
  return props.width
})
const slotsExist = useSlotsExist(['title', 'extra'])
const showHeader = computed(() => {
  return slotsExist.title || slotsExist.extra || props.title || props.extra
})
</script>
<template>
  <div
    class="m-card"
    :class="{ 'card-bordered': bordered, 'card-small': size === 'small' }"
    :style="`width: ${cardWidth};`"
