How to get linestretch option to not impact table generation?

Description

I would like to include tables in my pdf document that has different line spacing compared to rest of the document.

I noticed while writing a report that quarto linestretch will override flextable's line_spacing command. I can't tell if this is a bug or if there is a combination of commands that will make flextable line_spacing to work correctly or if we can make a local environment that has a custom line spacing. I tired the results: asis to get around the formatting but that did not work. I provided a simple example:

---
title: "Untitled"
format: 
  pdf:
    linestretch: 2
---

```{r}
library(flextable)
```
```{r}
#| tbl-cap: This is a table
dat<- iris[1:5,]
flextable(dat) |> 
  line_spacing(space = .5)
```


```{r}
#| tbl-cap: This is a table
#| results: asis
dat<- iris[1:5,]
flextable(dat) |> 
  line_spacing(space = .5) |> 
  flextable_to_rmd()

```

I am on quarto verison 1.4.534, Windows 11.

In the meantime, I save the flextable separately and import them as high quality png in my reports.

You can't (pretty sure but not 100 %).
That's LaTeX limitation I believe.
You'll have better luck looking for workaround/hack on places more dedicated to LaTeX.

Using the setstretch command it will work but will impact the spacing of the code block as well. Which is fine for my needs. I tried manipulating the line-height directly with CSS and that did not work if I did it correctly.

title: "Untitled"
format: 
  pdf:
    linestretch: 2
engine: knitr
---

```{css}
.table_format {
  line-height: .5;
}   
```

```{r}
library(flextable)
```
```{r}
#| tbl-cap: This is a table
dat<- iris[1:5,]
flextable(dat)
```


\setstretch{1.0}
```{r}
#| tbl-cap: This is a table
flextable(dat)
```

\setstretch{2}

```{r}
#| class-output: table_format
#| tbl-cap: This is a table
dat<- iris[1:5,]
flextable(dat)
```

LaTeX has nothing to do with HTML/CSS.
It's a completely different and independent technology/language.

Linestretch is a page setup in LaTeX. It applies on every lines.
A table has lines (rows).
The same thing would happen in Word if you set line spacing, any content will abide by this setting.

You should raw code block/inline syntax to use LaTeX.
