图床项目进度（三）——文件展示页

前言

该项目作为一个类网盘项目，主要包括上传下载，引用，预览等功能。

大致功能：

1. 图片预览
   

这里的图片预览我使用的一个插件
const state: any = reactive({

  image: 'https://pic35.photophoto.cn/20150511/0034034892281415_b.jpg',
  index: 0
});

const previewEvent = () => {
  preview({
    images: state.image
  });
};

<el-button type="primary" size="small" @click="dialogVisible = true" :icon=Upload>上传图片</el-button>

3. 几个自定义标签
   

<el-table-column>
<!--        几个自定义图标-->
        <template v-slot="{row}">
          <div v-if="isPicture(row)" >
            <el-button  type="primary" round size="small" style="margin-right: 50px" @click="previewEvent">预览</el-button>
            <el-tooltip class="item" effect="dark" content="引用" placement="bottom-start">
            <el-button type="text">
              <el-icon>
                <Link/>
              </el-icon>
            </el-button>
           </el-tooltip>
          <el-tooltip class="item" effect="dark" content="下载" placement="bottom-start">
