这种数组在element中怎么合并列,数据是动态的

var arr2 = [

{

id: 1,

value:111,

totalfee: 60,

cost: 25,

starttime: '2021',

endtime: "2021-10-11",

<el-table-column align="center" label="具体详情">

<template slot-scope="scope">{{scope.row.reason}}</template>

</el-table-column>

</el-table-column>

</el-table>

vue中方法部分不知道改怎么动态合并,如下

objectSpanMethod({ row, column, rowIndex, columnIndex }) {

// if (columnIndex === 0) { //用于设置要合并的列

// if (rowIndex % 2 === 0) { //用于设置合并开始的行号

// return {

// rowspan: 2,     //合并的行数

// colspan: 1 //合并的列数,设为0则直接不显示

// };

// } else {

// return {

// rowspan: 0,

// colspan: 0

// };

// }

// }

},

回答:

可以对数据进行判断,定义数组来记录要合并的索引,第一条不合并,之后每一条,如果跟上一条一样,就进行记录,然后在colspan值处进行判断

官网示例
elementui也有合并行/列的例子,从上面链接点进去往下翻可以看见,倒数第二个例子。
