Entries in table aren't clearly separated

[LordMZTE]

Consider:

> [[foo, bar]; [1, 2], [3, 4]] | tree

└── value
    ├── foo
    │   └── 1
    ├── bar
    │   └── 2
    ├── foo
    │   └── 3
    └── bar
        └── 4

Here, the tree output does not make it clear that 1 2 and 3 4 are separate rows. Instead, a somewhat confusing notation is used where it looks like we have "duplicate keys".

Here are some suggestions on how I think this output could be improved:

# We could use a sort of separator line
└── value
    ├── foo
    │   └── 1
    ├── bar
    │   └── 2
    ├──----------------------------------
    ├── foo
    │   └── 3
    └── bar
        └── 4

# We could make the rows separate entries in the tree
└── value
    ├── 0
    │   ├── foo
    │   │   └── 1
    │   └── bar
    │       └── 2
    └── 1
        ├── foo
        │   └── 3
        └── bar
            └── 4

I think I prefer the former approach as this minimizes unecessary extra tree depth.

You could do this too

❯ [[foo, bar]; [1, 2], [3, 4]] | enumerate | tree
root
├── index
│   └── 0
├── item
│   ├── foo
│   │   └── 1
│   └── bar
│       └── 2
├── index
│   └── 1
└── item
    ├── foo
    │   └── 3
    └── bar
        └── 4

What would be cool would be something like this to make it very nushell-y.

root
├── ╭─#─┬─foo─┬─bar─╮
│   │ 0 │   1 │   2 │
│   ╰───┴─────┴─────╯
└── ╭─#─┬─foo─┬─bar─╮
    │ 1 │   3 │   4 │
    ╰───┴─────┴─────╯
