Ant-Design-Vue中，a-form-model嵌套table，并且支持动态添加输入框还支持表单校验

最终效果如下图，没填的会报空，填了的则正常

弹窗代码如下（直接复制肯定跑不了，自己设计一个按钮添加点击事件改变dialogAddVisible来显示）

      <a-modal
        title="新增敏感词"
        centered
        :width="864"
        :visible="dialogAddVisible"
        :confirm-loading="confirmLoading"
        ok-text="确认"
        @ok="onSubmit"
        @cancel="dialogAddVisible = false"
      >
        <a-form-model :model="addForm" ref="addForm">
          <a-table class="addForm" :columns="addColumns" :dataSource="dataSource" :pagination="false">
            <div slot="word" slot-scope="text, record, index">
              <a-form-model-item
                ref="word"
                :prop="`word[${index}]`"
                :rules="{ required: true, message: '敏感词不能为空', trigger: 'blur' }"
              >
                <a-input style="width: 288px" v-model="addForm.word[index]" />
              </a-form-model-item>
            </div>
            <div slot="type" slot-scope="text, record, index">
              <a-form-model-item
                :prop="`typee[${index}]`"
                :rules="{ required: true, message: '敏感词不能为空', trigger: 'blur' }"
              >
                <a-select style="width: 288px" placeholder="请选择分类" v-model="addForm.typee[index]">
                  <a-select-option v-for="item in typeOption" :key="item.id" :label="item.type" :value="item.type">
                    {{ item.type }}
                  </a-select-option>
                </a-select>
              </a-form-model-item>
            </div>
            <div slot="opreate" slot-scope="text, record">
              <a class="removeRowBTN" href="javascript:;" style="color: #3370ff" @click="handleDeleteAdd(text, record)"
                >删除</a
              >
            </div>
          </a-table>
        </a-form-model>
        <div style="height: 48px; line-height: 48px; text-align: center">
          <a-icon style="color: rgba(51, 112, 255, 1); font-size: 11px; margin-right: 10px" type="plus" />
          <a style="color: rgba(51, 112, 255, 1)" @click="addRow">添加行</a>
        </div>
      </a-modal>

部分使用到的data或者方法如下，拷贝进去可能不能运行，主要是分享一下思路。

每需要添加一行就往table的datasource里添加一个空数据站位字，使得表格多出一行，而重点是如何准确的获取每一行的数据并且监听和校验呢？

我设计的form叫addForm，里面的word和type是个数组，专门存对应的数据。在a-form-model里使用：form=“addForm”。重点来了，a-form-model-item的prop属性，这个我观察了官网的例子，发现，prop需要赋一个字符串，字符串的内容是form的属性，在这里，form的属性则是word和type这两个数组，又因为我有许多输入框，我用的是数组来对应那些输入框。所以prop应该是动态的，（每个输入框的prop不一样嘛），则写出了:prop="`word[${index}]`"。让prop等于word[0]/word[1]/word[2]这样。而input中的v-model也是对应着那个数据。从而达到了校验表单的效果
