Vue Element UI 动态表格与动态表头实现方案

本文介绍如何在Vue中结合Element UI实现动态表格渲染。通过父组件向子组件传递tableData和tableLabel，利用v-for循环动态生成el-table-column，从而支持动态表头和数据展示。该方法解决了静态表格无法灵活适配多变数据结构的问题，为后续列操作扩展奠定基础。

Vue动态表格实现概述

在Vue项目中集成Element UI时，可以通过封装表格组件来实现数据的动态渲染，同时支持动态生成表头。具体做法是在父组件中引入封装好的子表格组件，并将表格数据源和表头配置信息作为Props传递给子组件。

子组件模板结构

子组件内部的template模板结构如下：


<el-table 
  :data="this.tableData"
  height="400px" 
  max-height="400px" 
  size="small"
  row-class-name="row"
  cell-class-name="column"
  :row-style="setRowStyle"
  :cell-style="setColumnStyle"
  :highlight-current-row="true"
  @cell-click="cellClick"
  fit
  >
  <el-table-column
    v-for="(item, index) in tableLabel"
    :key="index" 
    :prop="item.prop" 
    :width="item.width" 
    :label="item.label">
  </el-table-column>
</el-table>

数据接收与处理

在子组件中通过props接收父组件传递的数据，包括表格数据tableData和表头配置tableLabel。


props: {
 tableData: { // 父组件传递过来的表格数据
    type: Array,
    default: []
  },
  tableLabel: { // 父组件传递过来的表头数据
    type: Array,
    default: () => {
      return []
    }
  }
}

父组件调用示例

父组件调用子组件的代码示例如下：


<file-table 
 :tableData="tableData"
 :tableLabel="tableLabel"
>
</file-table>


data() {
 return {
 // 子组件的表格数据
 tableData: [
  {id: 1, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},
  {id: 2, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},
  {id: 3, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},
  {id: 4, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},
  {id: 5, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},
  {id: 6, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},
  {id: 7, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},
  {id: 8, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},
  {id: 9, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},
  {id: 10, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},
  {id: 11, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},
  {id: 12, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05}
 ],
 // 子组件的表头数据
 tableLabel: [
      {label: '', width: '40', prop: 'id'},
      {label: '日期', width: '', prop: 'date'},
      {label: '销售量', width: '', prop: 'sales'},
      {label: '销售额', width: '', prop: 'sale'},
      {label: '成本', width: '', prop: 'const'},
      {label: '利润', width: '', prop: 'profit'}
    ]
 }
