利用element-ui的表格实现复杂合并单元格之二

利用element-ui的表格实现复杂合并单元格之二
前言
哈哈哈哈哈哈,为什么是之二呢,因为以前还有一篇,第一篇合并单元格的时候只考虑了当前列需要合并的数量,不知道我在说啥是吧,那就算了。
效果图
效果图解读:监测主体相同的需要合并,交易对方是以监测主体相同为前提条件合并,上限金额是仅当为翰林汇的时候才需要合并。
实现代码
思路就是从头遍历到脚,比较一下当前的值和上一个值是否相同,for example,第一条数据的的监测主体是aaa,此时的数组为[1],遍历的第二条数据和第一条比较是不是aaa,如果相同,那么此时的数组为[2,0],第三条还相同的话,[3,0,0],第四条不一样了,那么此时[3,0,0,1],第五条和第四条一样,[3,0,0,2,0],第六条和第五条不一样,[3,0,0,2,0,1],第七条和第六条不一样,[3,0,0,2,0,1,1],以此类推。。。。
数组的length和第几条是相同的哦,所以遍历下来数组的length和返回的长度是一样的哦,数组每一个元素就代表每一行需要合并的个数
需要注意的是element表格的 return { rowspan: 0,colspan: 0, }表示隐藏该单元格,return { rowspan: 1,colspan: 1, }表示合并一行一列
