这篇文章主要讲解了“vue如何实现树形结构表格”,文中的讲解内容简单清晰,易于学习与理解,下面请大家跟着小编的思路慢慢深入,一起来研究和学习“vue如何实现树形结构表格”吧!
在el-table中,支持树类型的数据的显示。当 row 中包含 children 字段时,被视为树形数据。渲染树形数据时,必须要指定 row-key。支持子节点数据异步加载。
通过指定 row 中的 hasChildren 字段来指定哪些行是包含子节点。children 与 hasChildren 都可以通过 tree-props 配置。
row-key="id"和:tree-props="{children: 'children', hasChildren: 'hasChildren'}是必须的。
下面是vue的表格树:
<!--表格-->
<el-row>
<el-table :data="tableData" row-key="id" :tree-props="{children: 'children', hasChildren: 'hasChildren'}">
<el-table-column prop="privilegeName" label="权限名称" >
</el-table-column>
<el-table-column prop="privilegeCode" label="权限编码" >
</el-table-column>
<el-table-column prop="privilegeType" label="权限类别" :formatter="formatPrivilegeType" >
</el-table-column>
<el-table-column label="操作">
<template slot-scope="scope">
<el-button type="primary" size="mini" @click="toAdd(scope)">新增</el-button>
<el-button type="primary" size="mini" @click="toEdit(scope)">编辑</el-button>
</template>
</el-table-column>
</el-table>
<br>
<el-pagination
@size-change="handleSizeChange"
@current-change="handleCurrentChange"
:current-page="pagination.pageIndex"
:page-sizes="[5, 10, 20, 30, 40]"
:page-size=pagination.pageSize
layout="total, prev, pager, next"
:total=pagination.total>
</el-pagination>
</el-row>

</el-button>

vue是什么
Vue是一套用于构建用户界面的渐进式JavaScript框架,Vue与其它大型框架的区别是,使用Vue可以自底向上逐层应用,其核心库只关注视图层,方便与第三方库和项目整合,且使用Vue可以采用单文件组件和Vue生态系统支持的库开发复杂的单页应用。
