分组和@ExcelCollection同时存在时，分组字段设置needMerge = true从分组第二项开始不生效

[hellojingbo]

class A {
    @Excel(name = "分组项1", replace = {"是_true", "否_false", "未填_null"}, orderNum = "37", needMerge = true, groupName = "分组")
    Boolean groupItem1;

    @Excel(name = "分组项2", replace = {"是_true", "否_false", "未填_null"}, orderNum = "37", needMerge = true, groupName = "分组")
    Boolean groupItem2;

    @Excel(name = "分组项3", replace = {"是_true", "否_false", "未填_null"}, orderNum = "37", needMerge = true, groupName = "分组")
    Boolean groupItem3;

    @ExcelCollection(name = "集合字段", orderNum = "26")
    List<B> collections;
}

这种情况分组项1正常合并，分组项2和3合并失效
