It would be really nice if @ssfrr 's [DeepDiffs.jl](https://github.com/ssfrr/DeepDiffs.jl) directly supported Tables.  
(probably displaying via PrettyTables.jl)  
But it does not

it does however support vectors

So some demos

```julia
julia> using DataFrames, DeepDiffs

julia> costs = DataFrame(brand=["BurgerDuke", "BurgerDuke", "BurgerDuke", "McDannys", "McDan
       nys"], product = ["burger", "fries", "drink", "burger", "drink"], price=[10.0, 5.0, 1.0, 9.5
       , 0.5])
5×3 DataFrame
 Row │ brand product price   
     │ String String Float64 
─────┼──────────────────────────────
   1 │ BurgerDuke burger 10.0
   2 │ BurgerDuke fries 5.0
   3 │ BurgerDuke drink 1.0
   4 │ McDannys burger 9.5
   5 │ McDan\nnys drink 0.5

julia> costs2 = DataFrame(brand=["BurgerDuke", "BurgerDuke", "BurgerDuke", "McDannys", "McDan
       nys"], product = ["burger", "fries", "drink", "burger", "drink"], price=[10.0, 7.0, 1.0, 9.5
       , 0.5])
5×3 DataFrame
 Row │ brand product price   
     │ String String Float64 
─────┼──────────────────────────────
   1 │ BurgerDuke burger 10.0
   2 │ BurgerDuke fries 7.0
   3 │ BurgerDuke drink 1.0
   4 │ McDannys burger 9.5
   5 │ McDan\nnys drink 0.5

```

by row

Perhaps best is to convert to dict:  
`as_dict(t) = getfield(Tables.dictcolumntable(t), :values)`
