可自定义设置以下属性：
自定义描述内容（description），类型：string | slot | null，默认 '暂无数据'
设置描述文本的样式（descriptionStyle），类型：CSSProperties，默认 {}
显示图片的链接，或者 选择两种预置风格图片（image），类型：'outlined' | 'filled' | string | slot，默认 'filled'
设置图片的样式（imageStyle），类型：CSSProperties，默认 {}
设置底部内容（footer），类型：slot，默认 undefined
效果如下图：在线预览
①创建空状态组件Empty.vue：
其中引入使用了以下工具函数：
<script setup lang="ts">
import { computed } from 'vue'
import type { CSSProperties } from 'vue'
import { useSlotsExist } from '../utils'
interface Props {
description?: string // 自定义描述内容 string | slot
descriptionStyle?: CSSProperties // 设置描述文本的样式
image?: 'filled' | 'outlined' | string // 显示图片的链接，或者 选择两种预置风格图片 string | slot
imageStyle?: CSSProperties // 设置图片的样式
footer?: string // 设置底部内容 string | slot
}
const props = withDefaults(defineProps<Props>(), {
description: '暂无数据',
descriptionStyle: () => ({}),
image: 'filled',
imageStyle: () => ({}),
footer: undefined
})
const slotsExist = useSlotsExist(['default', 'description', 'footer'])
const showDescription = computed(() => {
return slotsExist.description || props.description
})
const showFooter = computed(() => {
return slotsExist.footer || props.footer
})
</script>
