需求效果

1.隐藏bodyWrapper滚动条，显示footerWrapper滚动条
css代码如下：

div ::v-deep .el-table--scrollable-x .el-table__body-wrapper{overflow-x: hidden!important;z-index: 2!important;}
div ::v-deep .el-table__footer-wrapper {overflow-x: auto;border-top: 1px solid #f4f4f4;}

监听footerWrapper滚动条
在el-table上加上ref=“detailTable”

mounted() {
   var tableBody = this.$refs.detailTable.$refs.footerWrapper
   tableBody.addEventListener('scroll', () => {
     const scrollLeft = tableBody.scrollLeft
     this.$refs.detailTable.$refs.bodyWrapper.scrollLeft = scrollLeft
   })
},
