如上所示
表格内的数据是当前班级所在名次段的人数 / 当前班级1至n名的累计人数 5/12 也就是 5/75
需要变更为 截至到当前名次段总人数上次考试 / 截至到当前名次段总人数本次考试 人数最多的班级 标红加粗人数最少的班级 标蓝加粗。 先说一下第一种的实现方式就是用这种笨办法也能实现 el-table:datarankDatastylewidth: 100%:header-cell-styleheaderStyleEventborderclasspptTable:cell-stylecellStyleel-table-column propl51A100 label51-100 aligncentertemplate slot-scopescopespan{{ scope.row.l51A100 }}/{{ scope.row.l1A50 scope.row.l51A100 }}/span/template/el-table-columnel-table-column propl401A450 label401-450 aligncentertemplate slot-scopescopespan{{ scope.row.l401A450 }}/{{scope.row.l1A50 scope.row.l51A100 scope.row.l101A150 scope.row.l151A200 scope.row.l201A250 scope.row.l251A300 scope.row.l301A350 scope.row.l351A400 scope.row.l401A450}}/span/template/el-table-column/el-table优化后的代码

};

/style关键代码 computed: { rankArr() { let newRank _.cloneDeep(this.rankData); const accumulation newRank.map(v { delete v.classNo; return Object.values(v); }); return accumulation; } }, methods: { accumulate(index, columnIndex) { const countArr this.rankArr[columnIndex].slice(0, index 1); const sumByIndex countArr.reduce((prev, cur, i) { return prev cur; }, 0); return sumByIndex; } } 页面使用 accumulate方法 template slot-scopescope span{{ scope.row[item.value] }}/{{ accumulate(index, scope.$index) }}/span /template 以上是第一版的实现方式
现在来说说更新需求后的实现方式:(这里稍微复杂的点在颜色) 截至到当前名次段总人数上次考试 / 截至到当前名次段总人数本次考试 人数最多的班级 标红加粗人数最少的班级 标蓝加粗。
