<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 => {}
        );
    },
