Description

Hello! 🍁

Would it be possible to update cols_hide() to no longer error when no columns are selected?

Thanks!

Reproducible example

packageVersion("gt")
#> [1] '0.9.0'

gt::sp500 |> 
  gt::gt() |> 
  gt::cols_hide(columns = starts_with("xxxxx"))
#> Error in `gt::cols_hide()`:
#> ! Columns must be provided.
#> Backtrace:
#>     ▆
#>  1. └─gt::cols_hide(gt::gt(gt::sp500), columns = starts_with("xxxxx"))
#>  2.   └─cli::cli_abort("Columns must be provided.")
#>  3.     └─rlang::abort(...)

# in my real-world example, I wanted to hide columns that were all na
all_na <- function(x) all(is.na(x))

gt::sp500 |> 
  gt::gt() |> 
  gt::cols_hide(columns = where(all_na))
#> Error in `gt::cols_hide()`:
#> ! Columns must be provided.
#> Backtrace:
#>     ▆
#>  1. └─gt::cols_hide(gt::gt(gt::sp500), columns = where(all_na))
#>  2.   └─cli::cli_abort("Columns must be provided.")
#>  3.     └─rlang::abort(...)

Expected result

When no columns are selected, I expected simply no columns to be hidden rather than an error

[rich-iannone]

Great idea here, I think this should be done. And also done for cols_unhide()!
