需求：父容器里有多个容器为上下级，之后浏览器在缩放的时候，上面容器高度改变了，所以el-table被挤压，如果el-table设置的是固定的高度，那么挤压后内容超出父容器，本文章就是解决这个问题

不自适应错误用法：浏览器伸缩挤压后元素超出了

 1.在el-table的父容器上添加class

table_height_big：用于控制浏览器屏幕在大于多少时的样式

table_height_small'：浏览器宽高小于多少的样式

tableClass ：变量用于类名切换，默认在data中为true

关键代码：:class="tableClass ? 'table_height_big' : 'table_height_small'"

  <div class="container_main" :class="tableClass ? 'table_height_big' : 'table_height_small'"><el-table :data="tableData" style="width: 100%"><el-table-column type="index" label="序号" align="center"> </el-table-column><el-table-column prop="name" label="操作内容" align="center"> </el-table-column><el-table-column prop="address" label="设备类型" align="center"> </el-table-column></el-table><div class="table-page-right"><el-pagination@size-change="handleSizeChange"@current-change="handleCurrentChange":current-page="currentPage4":page-sizes="[100, 200, 300, 400]":page-size="100"layout="total, sizes, prev, pager, next, jumper":total="400"></el-pagination></div></div>

 2.类名样式修改

这个40px，是浏览器在大于多少的时候，最上面元素的值

124就是浏览器小于1350的时候，顶部元素高度值，可以根据自己的元素高度来调整

 

    .table_height_big {height: calc(100% - 62px);}.table_height_small {height: calc(100% - 124px);}
::v-deep .el-table {height: 88%;.el-table__body-wrapper {height: calc(100% - 48px) !important; // 表格高度减去表头的高度overflow-y: auto;}
}

3.在mounted中添加window.addEventListener用于监听浏览器的宽高

window.innerWidth：当前浏览器的宽度为多少，我这边写的是如果是小于1350的话就修改类名，这个值需要你自己测试下宽度为多少才会换行，换行的时候修改类名就行

   mounted() {this.internetCardQuery();window.addEventListener('resize', this.internetCardQuery);},methods: {internetCardQuery() {if (window.innerWidth < 1350) {this.tableClass = false;} else {this.tableClass = true;}}},

4.销毁时取消监听

   beforeDestroy() {// 取消监听window.removeEventListener('resize', this.internetCardQuery);}
