When rendering an HTML document using Quarto, light grey shading is added to alternate/odd-number rows for both {gt} and {DT} tabular output. The shading persists even when opt_row_striping(row_striping = FALSE) is included.
library(tidyverse)
library(gt)
set.seed(10)
x <- sample(1:nrow(iris), 10)
df <- iris[x, ]
df |>
gt() |>
opt_row_striping(row_striping = FALSE)
(Note: shading does not appear when generating and viewing the table in RStudio)
This shading does not appear in when knitting this same code as an HTML document using RMarkdown.
How can this either be turned off or set to a different color?
Thanks.

yes the shading is added by default on computational table output in Quarto
This can't be easily removed for now

### Bug description
In this issue, https://github.com/quarto-dev/quarto-cli/iss… ues/922#issuecomment-1640093837, there's a difference in how tables are rendered by default: non-computational tables made with Markdown don't have the `.striped` class included, while tables generated with chunks (like with `knitr::kable()` or with `gt::gt()` do.
The rational for including stripes and condensed spacing by default makes sense, since tables full of numbers often need to be more information-dense. Sometimes, though, {kable} and {gt} can be used to create less number-heavy tables and just present text. As of Quarto 1.4.376, the `.striped` class seems hard-baked-in and can't be removed, though (though I might be missing some option to disable it)
### Steps to reproduce
This example uses {gt} to generate a text-based table. Row striping appears (`<table class="gt_table table table-sm table-striped small" ...>`) regardless of the `row_striping` option in `gt::opt_row_striping()` (which is a gt thing, not a quarto thing, but quarto's table rendering is inserting its own table class here)

### Expected behavior
It would be nice to have a table without stripes. [In the documentation](https://quarto.org/docs/prerelease/1.3/tables.html#bootstrap-classes-can-be-added-to-tables) it shows that it's possible to add a bunch of different bootstrap classes to non-computational tables:
```
| fruit | price |
|--------|--------|
| apple | 2.05 |
| pear | 1.37 |
| orange | 3.09 |
: Fruit prices {.striped .hover}
```
### Actual behavior
However, that `.striped` class is hard-coded for computational output and there's no way I can find to disable it, so all kable and gt tables have stripes regardless of controlling stripes with kable- and gt-specific settings.
