el-table中 文字超出 用点点点显示

<div class = 'css'>

show-overflow-tooltip>

              <template slot-scope="scope">

                <div>{{scope.row.aa}}</div>

              </template>

            </el-table-column>

</div>

主要是样式写下

  .aa /deep/ .el-table .cell {

    overflow: hidden !important;

  }
