  <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',
