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。
