今天来实现个跨行跨列多列表格。

如图，这是个列数不确定，有的单元格还要跨行跨列的复杂表格。

这里暂时最多支持4列，列数再多就放不下了。

实现原理

实现原理比较简单，通过多个嵌套的循环将数据取出。

上面的例子中，最外层一共有4行：基础工资，加班工资，岗位工资，合计。第一层数据的 name 展示为第一列，如果每组数据有 children，取出 children 展示为第二列… 如果 children 长度为0，则直接显示工资数额。

这样一层一层把数据剖开，就做到了上面的效果。

数据格式

模拟的数据如下，如果是最后一层 value 值为工资数额，否则值为 null。嵌套的数据在 children 中。

// 模拟的数据
export default {status: 200,code: "ok",data: [{id: 'table001',name: '基础工资',value: null,children: [{id: 'table0011',name: '基本工资',value: 3000.0,children: []},{id: 'table0012',name: '绩效工资',value: 1200.0,children: []},{id: 'table0013',name: '基本工作量',value: null,children: [{id: 'table00131',name: '课时工资',value: 800.0,children: []},{id: 'table00132',name: '超课时工资',value: 200.0,children: []},]},]},{id: 'table002',name: '加班工资',value: null,children: [{id: 'table0021',name: '工作日加班',value: 1000.0,children: []},{id: 'table0022',name: '周末加班',value: 600.0,children: []},]},{id: 'table003',name: '岗位工资',value: 1800.0,children: []},{id: 'table004',name: '合计',value: 8600.0,children: []},]
}

逻辑很简单，主要是布局稍微复杂些，理清楚了也挺好理解。
