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。
