這篇文章主要給大家介紹了關(guān)于vue動(dòng)態(tài)合并單元格并添加小計(jì)合計(jì)功能的相關(guān)資料，文中通過示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧

1、效果圖

2、后臺(tái)返回?cái)?shù)據(jù)格式（平鋪式）

3、后臺(tái)返回?cái)?shù)據(jù)后，整理所需要展示的屬性存儲(chǔ)到（items）數(shù)組內(nèi)

var obj = {
    "id": curItems[i].id,
    "feeName": curItems[i].feeName,
    "projectName": curItems[i].projectName,
    "projectDetailsName": curItems[i].projectDetailsName,
    "zbMoney": curItems[i].zbMoney,
    "qyMoney": curItems[i].qyMoney,
    "projectId": curItems[i].projectId,
    "instructions": curItems[i].instructions,
    "contentText": curItems[i].contentText,
    "measureText": curItems[i].measureText
   }
   if (curItems[i].projectDetailsName == '合計(jì):') {
    obj.projectName = curItems[i - 1].projectName
   }
   _self.items.push(obj)
   }

4、調(diào)用initData(調(diào)用后會(huì)刪除需要合并的字段內(nèi)容)

_self.initData()

initData(){
  const that = this;
  let arry = [];
  let itemsCopy = JSON.parse(JSON.stringify(that.items));
  for (let i = 0; i < itemsCopy.length; i++) {
   for (let j = (i + 1); j < itemsCopy.length; j++) {
   for (let h in itemsCopy[i]) {
    for (let k in itemsCopy[j]) {
    if (k == 'feeName' || k == 'projectName' || k == 'projectDetailsName') {
     if (itemsCopy[j][k] != '小計(jì):' && itemsCopy[j][k] != '合計(jì):') {
     if (h === k && itemsCopy[i][h] === itemsCopy[j][k]) {
      delete itemsCopy[j][k]
     }
     }
    }
    }
   }
   }
   arry.push(itemsCopy[i]);
  }
  that.dataT = arry;
  },

4、合并行數(shù)的代碼

rowSpanF: function (key, val) {
  const that = this;
  let num = 0;
  for (let i in that.items) {
   for (let j in that.items[i]) {
   if (j == 'feeName' || j == 'projectName' || j == 'projectDetailsName') {
    if (key === j && val === that.items[i][j]) {
    if (that.items[i][j] == '小計(jì):' || that.items[i][j] == '合計(jì):') {
     return
    }
    num++;
    }
   }
   }
  }

  if(num==0){
   return 1
  }
  return num;
  },

5、html

代碼如下：

<tr v-for="(item,$index) in dataT">　　 　　　　
   <td
   v-if="key!='id'&&(key=='feeName'||key=='projectName'||key=='projectDetailsName'||key=='zbMoney'||key=='qyMoney'||key=='projectId'||key=='instructions'||key=='contentText'||key=='measureText')"
   v-for="(val,key) in item" :rowspan="rowSpanF(key,val)">
   <span v-if="key=='feeName'">{{val}}</span>
   <span v-if="key=='projectName'">{{val}}</span>
   <span v-if="key=='projectDetailsName'">{{val}}</span>
   <span v-if="key=='zbMoney'">{{val}}</span>
   <span v-if="key=='qyMoney'">{{val}}</span>
   <span v-if="key=='projectId'">{{item['zbMoney']+item['qyMoney']}}</span>
   <span v-if="key=='instructions'">{{val}} </span>
   <span v-if="key=='contentText'">{{val}}</span>
   <span v-if="key=='measureText'">{{val}}</span>
   </td>
   <td>
   <div v-if="item.projectDetailsName!='小計(jì):'&&item.projectDetailsName!='合計(jì):'">
    <!--<span @click="toAdd(allItems[$index])"><a>添加</a></span>-->
    <span @click="toEdit(item)"><a>編輯</a></span>
    <span>
     <a-popconfirm
     title="確定刪除嗎?"
     okText="確定"
     cancelText="取消"
     @confirm="() => deletArr(item)">
      <a href="javascript:;" rel="external nofollow" >刪除</a>
     </a-popconfirm>
    </span>
   </div>
   </td>　　　　
  </tr>

注意事項(xiàng)：

后臺(tái)返回?cái)?shù)據(jù)必須符合該條件
