antdesign的表格里嵌套输入框，并对输入框做校验

<template>
  <div class="tableForm">
    <div style="width:1200px;margin:50px auto;">
      <a-table :columns="columns" :data-source="data">
        <a-form-model
          slot="wage"
          slot-scope="text,record"
          :ref="record.index"
          :model="record"
          :rules="rules"
          style="width:300px;height:40px"
        >
          <a-form-model-item prop="wage">
            <a-input style="width:100%" v-model="record.wage" />
          </a-form-model-item>
        </a-form-model>
        <span slot="action">
          <a>详情</a>
        </span>
      </a-table>
    </div>

    <div style="margin-top:50px;overflow:hidden;text-align:center">
      <a-button @click="submit" size="large" type="primary">提交</a-button>
    </div>
  </div>
</template>
