创建间距组件Space.vue

<script setup lang="ts">
import { computed } from 'vue'
interface Props {
  width?: string | number // 区域总宽度，单位 px
  align?: 'stretch' | 'start' | 'end' | 'center' | 'baseline' // 垂直排列方式
  vertical?: boolean // 是否为垂直布局
  gap?: number | number[] | 'small' | 'middle' | 'large' // 间距大小，数组时表示: [水平间距, 垂直间距]
  wrap?: boolean // 是否自动换行，仅在 horizontal 时有效
}
const props = withDefaults(defineProps<Props>(), {
  width: 'auto',
  align: 'start',
  vertical: false,
  gap: 'middle',
  wrap: true
})
const spaceWidth = computed(() => {
  if (typeof props.width === 'number') {
    return props.width + 'px'
  }
  return props.width
})
const gapValue = computed(() => {
  if (typeof props.gap === 'number') {
    return props.gap + 'px'
  }
  if (Array.isArray(props.gap)) {
    return props.gap[1] + 'px ' + props.gap[0] + 'px '
  }
  if (['small', 'middle', 'large'].includes(props.gap)) {

      small: '8px',
      middle: '16px',
      large: '24px'
    }
    return gapMap[props.gap]
  }
})
</script>
<template>

    class="m-space"
    :class="[`space-${align}`, { 'space-vertical': vertical, 'space-wrap': wrap }]"
    :style="`width: ${spaceWidth}; gap: ${gapValue}; margin-bottom: -${Array.isArray(props.gap) && wrap ? props.gap[1] : 0}px;`"

在要使用的页面引入
