> Related to ARROW-16776 but after a brief discussion with Neal Richardson, he requested that I split the improvement request into separate issues.
> When working with Arrow datasets/tables, I often find myself wanting to interactively print or "see" the results of a query or the first few rows of the data without having to fully collect into memory. 
> It would be ideal to lazily print some data with Table/RecordBatch print methods, however, currently, the print methods return schema without data. 
> IE:
> ``` r
> library(dplyr)
> library(arrow)
> mtcars %>% arrow::write_parquet("mtcars.parquet")
> car_ds <- arrow::open_dataset("mtcars.parquet")
> car_ds
> #> FileSystemDataset with 1 Parquet file
> #> mpg: double
> #> cyl: double
> #> disp: double
> #> hp: double
> #> drat: double
> #> wt: double
> #> qsec: double
> #> vs: double
> #> am: double
> #> gear: double
> #> carb: double
> #> 
> #> See $metadata for additional Schema metadata
> car_ds %>%
>   compute()
> #> Table
> #> 32 rows x 11 columns
> #> $mpg <double>
> #> $cyl <double>
> #> $disp <double>
> #> $hp <double>
> #> $drat <double>
> #> $wt <double>
> #> $qsec <double>
> #> $vs <double>
> #> $am <double>
> #> $gear <double>
> #> $carb <double>
> #> 
> #> See $metadata for additional Schema metadata
