[GitHub] [spark] HyukjinKwon edited a comment on pull request #29645: [SPARK-32796][SQL] Make withField API support nested struct in array

   I personally more prefer an explicit call such as `transform($"struct_col", _.withField("new_col", col))` more as it's more explicit but I got that this can be sort of similar with  the nested column access in SQL like `a.b` supports the arrays of structs. No strong opinion on this. WDYT @cloud-fan.
