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" 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。
