el-table 每一行 的单元格内带upload 上传；并加载附件

.附件上传

我写的是选取文件后，直接上传与存数据库，所以不需要做太多操作；

重点难点是加载每一行单元格内的附件

<template slot-scope="scope">
          <el-upload
            ref="upload"
            :limit="10"
            :action="upload.url"
            :headers="upload.headers"
            multiple
            :file-list="scope.row.fileList"
            :on-exceed="handleExceed"
            :before-upload="beforeAvatarUpload"
            :on-remove="handleRemove"
            :on-progress="handleFileUploadProgress"
            :on-success="
    (response, file, fileList) =>
      handleFileSuccess(
        response,
        file,
        fileList,
        scope.$index
      )
  "
            :on-preview="handlePreview"
            :auto-upload="true">
            <el-button slot="trigger" size="small" type="primary" @click="savefile(scope.row)">选取文件</el-button>
<!--          <el-button style="margin-left: 30px;margin-top: 20px" size="small" type="primary" :loading="upload.isUploading" @click="submitUpload">确认</el-button>-->
        </el-upload>
        </template>

:file-list 属性不能再data中写固定的定义
js中循环给fileList 赋值与置空

this.xueqianxxList.forEach((item)=>{
                           // console.log("item---",item)
                            if (item.filepath!=null&&item.filepath!=""){
                                this.fileList=[]
                                item.filepath.split('|').forEach((item) => {
                                    if (item.trim().length > 0) {
                                           this.fileList.push({name: decodeURIComponent(item.substring(item.lastIndexOf('/') + 1)), url: item})
                                    }
                                })
                                item.fileList = this.fileList;
                            }else{
                                item.fileList = [];
                            }


                        })
