使用element table的展开行功能，代码如下：
<el-table
:data="tableData5"
style="width: 100%">
<el-table-column
type="selection"
:width="100"
align="center">
</el-table-column>
<el-table-column type="expand" >
<template>
<el-table style="width: 100%" :show-header="false" :data="tableData5" class="demo-table-expand">
<el-table-column
:width="100"
fixed
align="center">
</el-table-column>
<el-table-column

fixed
align="center">

/deep/ .el-table__expanded-cell {
padding: 0;
然后，子表出现横向滚动条了：
如果使用： ::-webkit-scrollbar{display:none;}
父表最下面的滚动条也没有了，
请问如何去掉横向滚动条？
