vue3+antd table 只校验选中的数据中必填字段

 - 动态校验层级较深的必填字段、自定义校验
 

```html
<template>
  <a-button type="primary" ghost @click="handleSubmit"></a-button>
  <a-form :model="tableData" ref="tableFormRef">
    <a-table
      :columns="columns"
      :data-source="tableData"
      :row-selection="rowSelection"
      :rowKey="(record) => record.id"
    >
      <template #bodyCell="{ column, record, index }">
        <template v-if="column.key === firstContactListName">
          <span v-for="(item, ind) in firstContactList" :key="ind">
          // 校验联系人name必填
          // isSeledted返回值为true时，给a-form-item加name的规则 否则为null 没有规则就不校验；
            <a-form-item
              :name="isSeledted(record) ? [index, 'firstContactList', ind, 'name'] : null"
              :rules="{
                message: '联系人name必填',
                trigger: 'blur',
                required: true
              }"
            >
              <a-input
                v-model:value="item.name"
                :disabled="record.status === '1' ? true : false"
              />
            </a-form-item>
          </span>
        </template>
      </template>
