Description
目前看SPL的序列/序表并不要求强数据结构,看文档上提到了泛型性。测试序表的某列取值可以是不同类型,进而生成的集文件和组表也如此,那么问题是能否提供对列类型强约束的选项?即生成组表时支持统一字段类型约束,这样可以保证较高的数据质量。
另外想了解一下,序表(或组表)列允许不同类型的意义何在?毕竟目前处理的结构化数据一般都是规范的,如果不规范通常也无法计算。

Research direction
The issue names no implementation files, entry points, or tests. Start by locating the sequence-table and group-table type handling in the repository, then review how heterogeneous column values are currently represented and generated. Done would require an agreed design for optional uniform column-type constraints, its behavior, and tests covering the resulting group tables.
