1、效果图
2、后台返回数据格式（平铺式）
3、后台返回数据后，整理所需要展示的属性存储到（items）数组内
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 == '合计:') {
obj.projectName = curItems[i - 1].projectName
}
_self.items.push(obj)
}
4、调用initData(调用后会删除需要合并的字段内容)
_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] != '小计:' && itemsCopy[j][k] != '合计:') {
if (h === k && itemsCopy[i][h] === itemsCopy[j][k]) {
delete itemsCopy[j][k]
}
}
}
}
}
}
arry.push(itemsCopy[i]);
}
that.dataT = arry;
},
4、合并行数的代码
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] == '小计:' || that.items[i][j] == '合计:') {
return
}
num++;
}
}
}
}
if(num==0){
return 1
}
return num;
},
5、html
代码如下：
<tr v-for="(item,$index) in dataT">
<td
v-if="key!='id'&&(key=='feeName'||key=='projectName'||key=='projectDetailsName'||key=='zbMoney'||key=='qyMoney'||key=='projectId'||key=='instructions'||key=='contentText'||key=='measureText')"
v-for="(val,key) in item" :rowspan="rowSpanF(key,val)">
<span v-if="key=='feeName'">{{val}}</span>
<span v-if="key=='projectName'">{{val}}</span>
<span v-if="key=='projectDetailsName'">{{val}}</span>
<span v-if="key=='zbMoney'">{{val}}</span>
<span v-if="key=='qyMoney'">{{val}}</span>
<span v-if="key=='projectId'">{{item['zbMoney']+item['qyMoney']}}</span>
<span v-if="key=='instructions'">{{val}} </span>
<span v-if="key=='contentText'">{{val}}</span>
<span v-if="key=='measureText'">{{val}}</span>
</td>
<td>
<div v-if="item.projectDetailsName!='小计:'&&item.projectDetailsName!='合计:'">
<!--<span @click="toAdd(allItems[$index])"><a>添加</a></span>-->
<span @click="toEdit(item)"><a>编辑</a></span>
<span>
<a-popconfirm
title="确定删除吗?"
okText="确定"
cancelText="取消"
@confirm="() => deletArr(item)">
<a href="javascript:;" rel="external nofollow" >删除</a>
</a-popconfirm>
</span>
</div>
</td>
</tr>
注意事项：
后台返回数据必须符合该条件
