使用 render 函数封装高扩展的组件

<FormTable :data="lessonPackageArr" :fleldsInfo="lessonPackageInfo" :maxColumn="3" label-width="120px">
  <template #presentedHours="{ data }">
    <div class="flex-box between">
      <span>

      </span>
      <span class="column-btn" @click="editPresentedHours(data)">修改</span>
    </div>
  </template>
  <template #gifts="{ data }">
    <div class="flex-box between">
      <span>
        {{ data.gifts }}
      </span>
      <span class="column-btn" @click="editPresentedHours(data)">修改</span>
    </div>
  </template>
</FormTable>

// 一个对象，用于配置标题列和标题列对应的字段
// type 指定值的类型，现在组件内部设置可能显示哪些类型的值了
// 对于服务其返回 1 0 需要显示 是否的数，提供一个 map_data 来映射
// column 属性设置跨列
// 需要自定义显示内容 提供 slot
