vue 使用elementUI表格动态行合并
需求背景
在开发中又是表格合并的行数并不是固定的行数,需要根据接口返回的数据来动态合并需要合并的行数
html代码:
<el-table
:data="tableData"
border
:span-method="objectSpanMethod"
>
<el-table-column label="前面" align="center">
<el-table-column prop="inquiryCode" label="id" align="center" />
<el-table-column prop="phoneNumber" label="1" align="center" />
<el-table-column prop="createTime" label="2" align="center" />
<el-table-column prop="createTime" label="3" align="center" />
<el-table-column prop="contractCount" label="4" align="center" />
</el-table-column>
<el-table-column label="中间" align="center">
<el-table-column prop="bankName" label="6" align="center" />
<el-table-column prop="acceptanceAmount" label="7" align="center" />
<el-table-column prop="dueTime" label="8" align="center" />
<el-table-column prop="dueDay" label="9" align="center" />
<el-table-column prop="interestAmount" label="10" align="center" />
</el-table-column>
<el-table-column label="总计" align="center">
<el-table-column prop="cashPayAmount" label="11" align="center" />
<el-table-column prop="acceptanceAllAmount" label="12" align="center" />
<el-table-column prop="payAllAmount" label="13" align="center" />
<el-table-column prop="interestAllAmount" label="14" align="center" />
</el-table-column>
</el-table>
js代码:(注意:此处我是根据接口返回的inquiryCode是否相同来确实是否需要合并,你如果是其他字段自行更改)
export default {
data() {
return {
tableData: [],
spanArr: [],
}
},
mounted() {
this.rowspan();
},
methods: {
rowspan() {
// 每次调用清空数据
this.spanArr = []
this.position = 0
this.tableData.forEach((item, index) => {
if (index === 0) {
this.spanArr.push(1)
this.position = 0
} else {
// inquiryCode 为需要合并查询的项
if (this.tableData[index].inquiryCode === this.tableData[index - 1].inquiryCode) {
this.spanArr[this.position] += 1
this.spanArr.push(0)
} else {
this.spanArr.push(1)
this.position = index
}
}
})
},
objectSpanMethod({ row, column, rowIndex, columnIndex }) {
if (columnIndex === 0 || columnIndex === 1 || columnIndex === 2 || columnIndex === 3 || columnIndex === 4 || columnIndex === 10 || columnIndex === 11 || columnIndex === 12 || columnIndex === 13) {
const _row = this.spanArr[rowIndex]
const _col = _row > 0 ? 1 : 0
return {
rowspan: _row,
colspan: _col
}
}
},
}
}

vue elementUI动态删除表格当前行内容
具体步骤
第一步:拿到当前行数据的索引
第二部:绑定函数置删除键将拿到的数据索引通过请求发送给后端
第三部,调用获取数据借口(这样就不用删除数据后还要再次刷新页面,用户体验会更好)
实现方法
首先获取将要被删除行的数据索引
<el-card class="box-card">
<el-table
:data="tableData"
border
stripe
style="width: 100% "
@selection-change="handleSelectionChange"
>
<el-table-column type="selection" width="55" align="center"></el-table-column>
<el-table-column prop="id" label="学号" align="center"></el-table-column>
<el-table-column prop="name" label="姓名" align="center"></el-table-column>
<el-table-column prop="sex" label="性别" align="center"></el-table-column>
<el-table-column prop="college" label="学院" align="center"></el-table-column>
<el-table-column label="操作" align="center">
<template slot-scope="scope" class="active">
<el-button @click="editData(scope.row)" type="primary" icon="el-icon-edit" circle></el-button>
<el-button @click="removeData(scope.row.id)" type="danger" icon="el-icon-delete" circle></el-button>
</template>
</el-table-column>
</el-table>
<el-row :gutter="20">
<el-col :span="6" :offset="12">
<div class="block">
<el-pagination
background
@current-change="handleCurrentChange"
:current-page.sync="currentPage"
:page-size="pageSize"
layout="total, prev, next, jumper, pager"
:total="total"
></el-pagination>
</div>
</el-col>
</el-row>
</el-card>
在这一步中,获取当行数据使用的方法是 scope.row.id 。这将把当行数据的id传递给删除函数
接下来就是删除函数的逻辑实现了
在这一步中需要注意的是,请求成功后应该调用一次获取数据列表的函数,否则需要刷行页面才看得到删除的效果
removeData(id) {
//提示框,判断用户是否操作失误
this.$confirm("此操作将永久删除此学生, 是否继续?", "警告", {
confirmButtonText: "继续",
cancelButtonText: "取消",
type: "warning"
})
.then(() => {
const data = { id }; //这里<=>data = {id:id}
axios
.post("URL", data)
.then(response => {
this.fetchdata(); //删除数据后重新获取数据
})
.catch(() => {
this.$message({
type:"warning",
message:"请求失败,请检查网络设置"
})
});
})
.catch(() => {
this.$message({
type: "info",
message: "已取消删除"
});
});
}
以上为个人经验,希望能给大家一个参考,也希望大家多多支持编程网。
