记录一下这次遇到的问题，要求是去掉el-table所有的内外边框线

elementui的边框线去除

// 去掉所有的横线
.el-table__row>td{ border: none; }
.el-table::before { height: 0px; }

// 只去除表格的最最底部的横线
div /deep/ .el-table--border::after,
div /deep/ .el-table--group::after,
div /deep/ .el-table::before {
	background-color: transparent;
} 

iviewui的table边框线去除

// 整个table的下边框和右边框
	/deep/ .ivu-table:before,/deep/ .ivu-table:after{
	  background: white;
	}
// table中所有的横边框 
	/deep/ .ivu-table td,/deep/ .ivu-table th{
	  border-bottom: 1px solid white;
	}
// 整个table的上边框和左边框
	/deep/ .ivu-table-wrapper {
	  border: none;
	}
