效果图

这个组件只有四个按钮，添加，上传、下载、删除，其中删除按钮的颜色默认是灰色，当表格有数据选中时再变成红色

实现 

组件代码

<script lang="ts" setup>
import { Icon } from '@/components/Icon/index'
import { useI18n } from '@/hooks/web/useI18n'

const { t } = useI18n()

defineProps({
  addBtnShow: {
    type: Boolean,
    default: false
  },
  selAddColor: {
    type: Boolean,
    default: false
  },
  importBtnShow: {
    type: Boolean,
    default: false
  },
  emportBtnShow: {
    type: Boolean,
    default: false
  },
  deleteBtnShow: {
    type: Boolean,
    default: false
  },
  selDelColor: {
    type: Boolean,
    default: false
  }
})
const emit = defineEmits(['click:add', 'click:import', 'click:emport', 'click:delete'])
</script>
