  :visible.sync="isShow"
  :before-close="beforeClose"
  title="自定义设备类型属性">
  <div class="dialogDiv">
   <el-table 
    :data="tableData.filter(data => handleAdd || data.name.toLowerCase().includes(handleAdd.toLowerCase()))" 
     border>
    <el-table-column prop="code" 
     :label="$t('basicData.device.propDlg.code')">
    </el-table-column>
    <el-table-column prop="maxValue" 
     :label="$t('basicData.device.propDlg.maxValue')">
    </el-table-column>
    <el-table-column prop="minValue" 
     :label="$t('basicData.device.propDlg.minValue')">
    </el-table-column>
    <el-table-column prop="name" 
     :label="$t('basicData.device.propDlg.name')">
    </el-table-column>
    <el-table-column prop="valueType" 
     :label="$t('basicData.device.propDlg.valueType')">
    </el-table-column>
    <el-table-column prop="warning" 
     :label="$t('basicData.device.propDlg.warning')">
    </el-table-column>
    <el-table-column align="center" width="160px">
     <template slot="header" slot-scope="scope">
      <el-button v-model="handleAdd" 
       size="mini"
       type="success"
       circle plain
       icon="el-icon-plus"
       @click="handleAdd(scope.$index, scope.row)">      
      </el-button>
     </template>
     <template slot-scope="scope">
      <el-button
       size="mini"
       type="primary"
       circle plain
       icon="el-icon-edit"
       @click="handleEdit(scope.$index, scope.row)">
      </el-button>
      <el-button
       size="mini"
       type="danger"
       circle plain
       icon="el-icon-delete"
       @click="handleDelete(scope.$index, scope.row)">
      </el-button>
     </template>
    </el-table-column>
   </el-table>
  </div>
  <span slot="footer">
   <el-button @click="cancel">{{ $t('common.cancel') }}</el-button>
   <el-button @click="confirm" type="primary">{{ $t('common.confirm') }}</el-button>
  </span>
 </el-dialog>
</template>

<script>
export default {
 data() {
  return {
   tableData: []
  }
 },
 methods: {
  // 添加
  handleAdd() {
  },
  // 编辑
  handleEdit(index, row) {  
  },
  // 删除
  handleDelete(index, row) {
  },
  cancel() {
   this.$emit("cancel")
  },
  confirm() {
   this.$emit("confirm", this.tableData)
  }
 }
};
</script>

<style lang="scss" scoped>
.dialogDiv {
 height: 300px;
 overflow: auto;
}
</style>
