通过在vue中使用element的table表格,实现数据动态渲染,并且动态渲染表头。通过在父组件中引入子组件表格,然后向子组件传递表格数据和表头数据。

子组件table中template模板


<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>

接收父组件传过来的数据


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


<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'}
 ]
 }
}

问题:这种方式只能在一个组件中动态渲染,但是当我们需要操作每一列数据的时候,没法操作,因为element table再带的方法是每个单元格点击事件,而不符合我们需求,如何能实现表格动态渲染,并且每个组件都能使用,还能够实现操作的可控的列,下节分享。
