Can't navigate to revealjs slides if the slide title is the same as column label from gt / great_tables output

[mine-cetinkaya-rundel]

Quarto version 1.5.37

If a slide has the same title as the column label of a gt/great_tables table, it's impossible to navigate to that slide. I can't replicate this issue with other table packages I've tried (e.g., knitr or itables).

R / gt

title: title
format: revealjs
---

## great_tables

```{r}
library(gt)
gt(head(gtcars, n = 10))

mfr

some text

model

1 + 1

gt (and great_tables) are setting id for each column in a table. Example

<th id="mfr" class="gt_col_heading gt_columns_bottom_border gt_left" data-quarto-table-cell-role="th" scope="col">mfr</th>

That is quite surprising as in a HTML document, an id should be unique, so it could create conflict in other usage than in Quarto.

For Quarto, this is a problem as by default, slide title are used for navigation, using title slide as hash in url.

Current workaround

• Setting an id on the header # mfr {#mfr-2}
• Using number as has type to avoid id clash in navigation

  format: 
    revealjs:
      hash-type: number

I don't know exactly if Quarto should do something here, like detect gt or great table is used, and so something.

It seems like gt or great_tables could just not set id when inside Quarto context, or used a prefix like gt-<colname> to avoid any conflict. I don't know what those ids are used for ... cc @rich-iannone
