latex equations in tables with quarto/revealjs?

Question

I am using quarto with revealjs to make a presentation in rstudio. Code is as follows

---
title: "table_latex"
format: revealjs
---

## Quarto


```{r}
library(readr)
tbl1 <- read_csv("table.csv")
library(knitr)
library(kableExtra) 

kbl(tbl1, escape = FALSE) %>%
  kable_classic(full_width = F) %>%
    kable_styling(font_size = 24) %>%
      row_spec(2, color = "lightgray", background = "darkred")
```

table.csv is something like this:

var, val
$a$, 1
$b$, 2
$c$, 3

The output within rstudio looks fine, the rendered html looks bad.

Why the output is not the same?

Answer 1

I am not sure why your approach is not working, but it seems if you save the table in a variable and then cat() it along with results: asis, it works!! (Not sure why this workaround is needed though).

cat(tab)
```
