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。
