I am using Julia 1.5 in windows 10. I am just reading and practicing JuliaDB

```julia
> t = table([0.01, 0.05], [2,1], [3,4], names=[:t, :x, :y], pkey=:t)
> 
> insertcolafter(t, :t, :w, [0,1])
> ERROR: UndefVarError: insertcolafter not defined
> Stacktrace:
> [1] top-level scope at REPL[215]:1
> [2] include_string(::Function, ::Module, ::String, ::String) at .\loading.jl:1088

```

I don’t know why I am getting this error, I am getting the same error for the “insertcol”

```julia
julia> using JuliaDB

julia> t = table([0.01, 0.05], [2,1], [3,4], names=[:t, :x, :y], pkey=:t)
Table with 2 rows, 3 columns:
t x y
──────────
0.01 2 3
0.05 1 4

julia> insertcolsafter(t, :t, :w => [0,1])
Table with 2 rows, 4 columns:
t w x y
─────────────
0.01 0 2 3
0.05 1 1 4

```

Slightly wrong syntax. You may always have a look with:

```julia
help?> insertcolsafter
search: insertcolsafter

  insertcolsafter(t, after, map::Pair...)

  For each pair name => col in map, insert a column col named name after after. Returns a new table.

  Example
  ≡≡≡≡≡≡≡≡≡

  t = table([0.01, 0.05], [2,1], [3,4], names=[:t, :x, :y], pkey=:t)
  insertcolsafter(t, :t, :w => [0,1])

```

pressing ? and using TAB completion is of great help here.
