&lt;el-table ref="multipleTable" :data="tableDataNo" tooltip-effect="dark"  :class="tableHeaderUpOn == '展开' ? 'hideScrollNode' : ''"  &gt;
          &lt;el-table-column type="selection" width="60" align="center"&gt; </el-table-column&gt;
          <el-table-column :label="未学习"&gt;
            <template slot="header" slot-scope="scope"&gt;
              <i :class="tableHeaderUpOn == '展开' ? 'el-icon-caret-right' : 'el-icon-caret-bottom' " @click="tableDataNoClick"&gt;</i> {{'未学习'}}
            </template>
            <template slot-scope="scope">
              <el-tooltip class="item" effect="dark" :content="scope.row.ruleName" placement="top">
                <div style="cursor:pointer;overflow: hidden; text-overflow: ellipsis; white-space: nowrap;" @click="gotoBasisListAdd(scope.row)">
                  {{scope.row.ruleName}}
                </div>
              </el-tooltip>
              <div>

      ],
      tableHeaderUpOn: "展开",

    tableDataNoClick() {
      if (this.tableHeaderUpOn == "展开") {
        this.tableHeaderUpOn = "收起"
      } else {
        this.tableHeaderUpOn = "展开"
      }
    },

补充：

  <el-table-column
            label="全选"
            :render-header="(h, obj) => renderHeader(h, obj, '确定')"
            style="display: inline"
          > </el-table-column>

    // 自定义列名
    renderHeader(h, { column, $index }, type) {
      let that = this;
      return h("div", [
        // 列名称
        h("span", column.label),
        // 按钮
        h(
          "el-button",
          {
            props: {
              type: "primary",
              // size: 'small',
            },
            class: "el-icon-download",
            style: "margin-left: 15px;background:#169BD5;width:136px;",
            on: {
              click: function () {
                // that.clickButton(type);
              },
            },
          },
