<template slot="title">
        <div class="avue-crud__dialog__header">
            <span class="el-dialog__title">
            <span style="display:inline-block;background-color: #3478f5;width:3px;height:20px;margin-right:5px; float: left;margin-top:2px"></span>

            </span>
          <div class="avue-crud__dialog__menu" @click="dialogFull? dialogFull=false: dialogFull=true">
            <i class="el-icon-full-screen"></i>
