实例:

1.去掉table表头(加上:show-header="false")

<el-table
    :data="tableData"
    :show-header="false"
    style="width: 100%">
</el-table>

2.去掉table所有边框

::v-deep .el-table--border th.el-table__cell,
::v-deep .el-table td.el-table__cell {
  border-bottom: none !important;
}
 
::v-deep .el-table--border .el-table__cell {
  border-right:none !important;
}
 
::v-deep .el-table--group, .el-table--border{
  border: none !important;
}

注意:还会出现下边框情况

解决:

.el-table::before {
  height: 0;
}

3.去掉table背景颜色(颜色根据自己项目需要修改即可)

// 去掉el-table的所有背景颜色以及所有hover的颜色
::v-deep .el-table,
::v-deep .el-table .el-table__header-wrapper th,
::v-deep .el-table--border {
  background-color: transparent !important;
  color: #4AC3B9;
}
::v-deep .el-table tr,
::v-deep .el-table__body tr:hover > td {
  background-color: transparent !important;
}
