problem with using a custom EJS template -- Quarto rendering interferes and changes the html

[paciorek]

Description

I'm hoping to use my own EJS template that creates an HTML table. When I try to do so, I find that the Quarto rendering process is somehow modifying the HTML in my template, perhaps because Quarto is trying to process it as a Quarto listings table.

Here's a minimal example. First the qmd file where I initially just create a basic HTML table and then try to create the equivalent HTML table in an EJS template (albeit without having the template fill in any values -- it's all just straight HTML for simplicity here).

---
title: "Test"
listing:
  - id: test
    template: test.ejs
---

A table directly.

<table>
<tbody>
<tr>
<th scope="row" style="width: 20%">Hello</th>
<td style="width: 40%;"><strong style="background-color:purple; border-radius: 9px; padding: 5px;">text</strong></td>
<td style="width: 40%;">2</td>
</tr>
</tbody>
</table>

A table via a template.

::: {#test}
:::

Here is the EJS file.

```{=html}
<table>
<tbody>
<tr>
<th scope="row">Hello</th>
<td><strong style="background-color:purple; border-radius: 9px; padding: 5px;">text</strong></td>
<td>1</td>
</tr>
</tbody>
</table>
```

The result in the rendered .html file is that the HTML from the template has been modified. The th element has been turned into a td element and the styling on the strong element has been removed. Here's the relevant HTML produced for the template version of the table.

<table data-quarto-postprocess="true" class="table">
<tbody>
<tr class="odd">
<td data-quarto-table-cell-role="th" scope="row">Hello</td>
<td><strong>text</strong></td>
<td>1</td>
</tr>
</tbody>
</table>

Is there any way to just have the EJS template processed without Quarto doing additional processing?

Side note: I've found that I can hack it in some cases (e.g., by inserting a dummy <b></b> into the template before </tbody<, which causes this warning message WARNING: Unable to parse table from raw html block: skipping. when rendering. The result of that 'skipping' is that the HTML in my template is preserved (i.e., the th and strong are not messed with).

Could you format your post properly?
Also raw HTML should be in raw block to avoid Pandoc/Quarto parsing it weirdly, i.e., ```{=html}

You can share a Quarto document using the following syntax, i.e., using more backticks than you have in your document (usually four ````).

````qmd
---
title: "Reproducible Quarto Document"
format: html
---

This is a reproducible Quarto document using `format: html`.
It is written in Markdown and contains embedded R code.
When you run the code, it will produce a plot.

```{r}
plot(cars)
```

The end.
````

Whoops, I fixed the missing backtick and put the html in a raw block. Thanks/sorry.

Take a look at this https://quarto.org/docs/authoring/tables.html#disabling-quarto-table-processing

Thanks, that worked.

Is there something that can be done in the Quarto processing system to better handle this sort of situation -- namely that when a custom EJS template is used, it is left alone? It's not clear to me if the behavior I was experiencing is what the developers intend?
