<el-table :data="tableData" style="width: 100%" height="568px" @selection-change="handleSelectionChange" ref="table">
                <el-table-column type="selection" width="55">
                </el-table-column>
                <el-table-column prop="name" label="姓名" width="180">
                </el-table-column>
                <el-table-column prop="photo" label="照片" width="300">
                    <template slot-scope="scope">
                        <img :src="scope.row.src" alt="" srcset="" style="width:50px;height:50px;">
                    </template>
                </el-table-column>
                <el-table-column prop="password" label="密码" width="180">
                </el-table-column>
    
            </el-table>

调取列表接口填充数据，图片是二进制byte\[\]存放在数据库的；列表返回也是二进制；

一种;直接调取单独http请求返回图片，

created() {
            this.netAPI = NetAPI().get("device_administrator");
            this.$http.get(this.netAPI.find).then(
                res => {
                    this.tableData = res.body.data;
                    for (let item of res.body.data) {
                        item.src = this.netAPI.fileImg + item.id;
                       
                    }
                },
                err => {}
            );
        },

二种；拿到列表里面的图片二进制直接放在img里面显示，需要设置头

created() {
            this.netAPI = NetAPI().get("device_administrator");
            this.$http.get(this.netAPI.find).then(
                res => {
                    this.tableData = res.body.data;
                    for (let item of res.body.data) {
                       item.src = "data:image/jpg;base64,"+item.photo;
                    }
                },
                err => {}
            );
        },
