vue动态合并单元格并添加小计合计功能示例

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 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
