這篇文章主要介紹“vue中Element-ui表格如何實現樹形結構表格”，在日常操作中，相信很多人在vue中Element-ui表格如何實現樹形結構表格問題上存在疑惑，小編查閱了各式資料，整理出簡單好用的操作方法，希望對大家解答”vue中Element-ui表格如何實現樹形結構表格”的疑惑有所幫助！接下來，請跟著小編一起來學習吧！

前端效果展示:

在el-table中，支持樹類型的數據的顯示。當 row 中包含 children 字段時，被視為樹形數據。渲染樹形數據時，必須要指定 row-key。支持子節點數據異步加載。

通過指定 row 中的 hasChildren 字段來指定哪些行是包含子節點。children 與 hasChildren 都可以通過 tree-props 配置。

row-key="id"和:tree-props="{children: 'children', hasChildren: 'hasChildren'}是必須的。

下面是vue的表格樹：

 <!--表格-->  
       <el-row>
            <el-table :data="tableData"  row-key="id" :tree-props="{children: 'children', hasChildren: 'hasChildren'}">
                        <el-table-column prop="privilegeName" label="權限名稱" >
                        </el-table-column>
                        <el-table-column prop="privilegeCode" label="權限編碼" >
                        </el-table-column>
                        <el-table-column prop="privilegeType" label="權限類別" :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)">編輯</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>
