Create a new DataFrame Column that is of Type Array{Int64,2}

I need to track an Array{Int64.2} for each row in my data frame. The dimensions of the array are not standard across the rows. How do I instantiate that column before running through and filling it in later in my code?

Maybe like this?

julia> using DataFrames

julia> df = DataFrame(a = rand(5))
5×1 DataFrame
│ Row │ a        │
│     │ Float64  │
├─────┼──────────┤
│ 1   │ 0.106733 │
│ 2   │ 0.275735 │
│ 3   │ 0.867829 │
│ 4   │ 0.60976  │
│ 5   │ 0.65826  │

julia> df[!, :arraycol] .= Ref([0,0]);

julia> df
5×2 DataFrame
│ Row │ a        │ arraycol │
│     │ Float64  │ Array…   │
├─────┼──────────┼──────────┤
│ 1   │ 0.106733 │ [0, 0]   │
│ 2   │ 0.275735 │ [0, 0]   │
│ 3   │ 0.867829 │ [0, 0]   │
│ 4   │ 0.60976  │ [0, 0]   │
│ 5   │ 0.65826  │ [0, 0]   │

Like this?

column = Vector{Array{Int64, 2}}(undef, 10)
column[1] = rand(Int, 10, 2)
