利用vue如何实现一个动态表格提交参数的功能

<el-form
    :model="formData"
    >
    <div v-if="tableshow">
    <div v-for="(item,i) in control" :key="i"  >
     <el-form-item
     v-if="item.type=='input'"
     :key="item.name"
     :prop="item.name"
     label-width="100px">
     <label slot="label">{{ item.cnname }}:</label>
     <el-input v-model="item.value" size="mini" />
     </el-form-item>
     <el-form-item
     v-if="item.type=='time'"
     :key="item.name"
     :prop="item.name"
     label-width="100px">
     <label slot="label">{{ item.cnname }}:</label>
     <el-date-picker
      v-model="item.value"
      value-format="yyyy-MM-dd HH:mm:ss"
      type="date"
      placeholder="选择日期"/>
     </el-form-item>
    </div>
    <div >

     <el-button class="filter-item" type="primary" icon="el-icon-search" size="mini" @click="cmdsearch">
      {{ $t('table.search') }}
