Recently I come across a need for a 2D data structure like this, but I am not sure how to call it. Any advice how to call it?  
For example I have a data structure (called SortedDict2D) containing this table:

```julia
        1 3
-------------------------
"a" | "a1" "a3"
"c" | "c1" "c3"

```

It looks like a SortedDict 2D, for example if I insert horizontally  
insert\_h!( dict2D, “b” )  
it will become

```julia
       "1" "3"
-------------------------
"a" | "a1" "a3"
"b" | "b1" "b3"
"c" | "c1" "c3"

```

If I insert vertically:  
insert\_h!( dict2D, 2 )  
it will become

```julia
       "1" "2" "3"
-----------------------------
"a" | "a1" "a2" "a3"
"b" | "b1" "b2" "b3"
"c" | "c1" "c2" "c3"

```
