My guess is the issue was asking for some kind of pretty printing support. Do
you want to perhaps add a follow-up issue for actual table-printing support?
For example, here is what the "to string" looks like in various other
implementations:
>
> ### Python:
> ```
> pyarrow.Table
> strings: string
> ints: int32
> floats: float
> ----
> strings: [["one","two","three","four","five"]]
> ints: [[1,2,3,4,5]]
> floats: [[1,2,3,4,5]]
> ```
>
> ### C++
> ```
> strings: string
> ints: int32
> floats: float
> ----
> strings:
> [
> [
> "one",
> "two",
> "three",
> "four",
> "five"
> ]
> ]
> ints:
> [
> [
> 1,
> 2,
> 3,
> 4,
> 5
> ]
> ]
> floats:
> [
> [
> 1,
> 2,
> 3,
> 4,
> 5
> ]
> ]
> ```
>
> ### Rust:
> ```
> RecordBatch { schema: Schema { fields: [Field { name: "strings",
data_type: Utf8, nullable: false, dict_id: 0, dict_is_ordered: false, metadata:
{} }, Field { name: "ints", data_type: Int32, nullable: false, dict_id: 0,
dict_is_ordered: false, metadata: {} }, Field { name: "floats", data_type:
Float64, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {} }],
metadata: {} }, columns: [StringArray

I see. I thought the original issue might have been about making these types
easier to comprehend in a debugger, such as in Visual Studio. There the
debugger invokes `ToString` on an object, which usually returns a single line
of text which the debugger then displays. I think this current PR achieves that
goal, although I cannot know the intent of the original issue.
I have now created issue #36777 for adding pretty printing methods.
