How to Adjust Font Sizes in Imported Table in a PDF Document Compiled from Quarto?

Question

I'm using Quarto to generate a PDF document, and I want to adjust the font sizes, specifically in a table imported from an external file.

Here is a minimal reproducible example of what I need. The output should provide a way to define the font size of the table imported from tab.md

---
title: "My Document"
format: pdf
---

## Intro

I want to insert a table created with this code:

```{r}
#| message: false
library(modelsummary)
datasummary(hp + mpg ~ Factor(cyl) * mean, data = mtcars, output = "tab.md")
```

## Table

::: {#tbl-tab}

{{< include tab.md >}}

My Table
:::

How can I adjust the font sizes for Table 1 in my Quarto PDF document?
