tab_model() table for lme4 models generates a table processing warning in Quarto

[remlapmot]

Thanks so much for several great packages.

I have spotted that tables generated by tab_model() run on a multilevel model fit from the lme4 package generate a warning in Quarto which I was wondering whether you are aware of. Here's a reprex.

Save the following as say example.qmd

---
format:
  html:
    embed-resources: true
---
  
```{r}
library(sjPlot)
library(lme4)
fm1 <- lmer(Reaction ~ Days + (Days | Subject), sleepstudy)
tab_model(fm1)
```

Then render with (I'm on the current versions of Quarto 1.6.40 and sjPlot 2.8.17)

quarto::quarto_render(input = 'example.qmd')

or at the command line with

quarto render example.qmd

and in the output you'll see the following which is caused by the tab_model() table.

WARNING (/Applications/quarto/share/filters/main.lua:9319) Unable to parse table from raw html block: skipping.

It turns out that Quarto has a feature to disabled their processing of html tables, by adding the following attribute to the table html-table-processing: none.

https://quarto.org/docs/authoring/tables.html#disabling-quarto-table-processing

So simply adding that to the YAML options of the Quarto document (or to the specific code chunk options) avoids the warning.

It can be done programmatically by package authors

https://quarto.org/docs/authoring/tables.html#library-authors

I don't know enough html to know why Quarto doesn't like these tables but I note that it doesn't give the warning if I disable the items in the bottom of the table, e.g.

---
format:
  html:
    embed-resources: true
---
  
```{r}
library(sjPlot)
library(lme4)
fm1 <- lmer(Reaction ~ Days + (Days | Subject), sleepstudy)
tab_model(fm1, show.re.var = FALSE, show.obs = FALSE, show.r2 = FALSE, show.icc = FALSE, show.ngroups = FALSE)
```

So I thought I'd check whether you are aware of this.

I didn't check whether this warning is generated by other types of model.
