I am looking to remove nested list columns from a tibble with lists. For example in the list below I want to remove "affected\_rows" without specifically referencing the column name. How would i best approach this?

```
my_list <- list(
  a =
    tibble(
      code = c("ax","yz"),
      affected_rows =
        c(list(1:10),list(200))
    ),
  b = 
    tibble(
      workid = c("123","456"),
      sheet = c("sheet1", "sheet2")
    )
)

```
