效果:

分析原理:

一共就三步,仔细看看很简单,位置要加对,代码结构下边有demo

代码结构demo:

 <el-table-column
        label="操作"
        align="center"
        fixed="right"
        show-overflow-tooltip
      >
        <template slot-scope="scope">
          <el-button
            size="mini"
            type="text"
            icon="el-icon-plus"
            @click="handleAdds(scope.row)"
            >{{"新增" }}</el-button>
          <el-popover trigger="click">
            <el-button
              size="mini"
              type="text"
              icon="el-icon-edit"
              @click="handleUpdate(scope.row)"
              >{{ "编辑" }}</el-button
            >
            <el-button
              size="mini"
              type="text"
              icon="el-icon-delete"
              @click="handleDelete(scope.row)"
              >{{ "删除" }}</el-button
            >
            <el-button
              slot="reference"
              size="mini"
              title="更多"
              icon="el-icon-more"
              type="text"
            ></el-button>
          </el-popover>
        </template>
      </el-table-column>

老规矩复制粘贴  拿去试试   注意这次的demo只有操作列不是全部表格结构,,需要放到表格的</el-table>标签内
