```julia
julia> deleteat!(df, findall(==(:C), df.group)[2])
7×2 DataFrame
 Row │ group X     
     │ Symbol Int64 
─────┼───────────────
   1 │ A 101
   2 │ A 102
   3 │ B 103
   4 │ B 104
   5 │ C 105
   6 │ C 107
   7 │ C 108

```

Assumes that there _is_ a second line that starts with C i.e. assumes there are at least two `C`s in the `group` column.
