How to avoid columns of a table to be split across two rows in rmarkdown

I am trying to create a table and knit to PDF with an rmarkdown file:

---
title: "Untitled"
author: "L"
date: "2025-03-13"
output: pdf_document
---

```{r}

set.seed(84)
dt <- data.frame(month = rep(c(1:12), 10),
           value = sample(c("A", "B", "C"), 120, replace = TRUE))

addmargins(round(prop.table(table(dt$value, dt$month), 1)*100,2))

the knitted pdf file looks like this:

I do not like that the columns of the table are not on a single row;

I have tried many different options, like adding \tiny before creating the table, or by changing the font or the margins; however, I was not able to get the table on one row only, as the table was split even if a lot of space was left on the other side:

How can I force the table to be in one row only and not be split (even if this breaks the page or margins)?

Set width in options(). We can use the 'setup' code chunk right after the YAML for this.

title: "Untitled"
author: "L"
date: "2025-03-13"
output: html_document

```{r setup, include=FALSE}
options(width=100)
```

```{r}
set.seed(84)
dt = data.frame(month = rep(c(1:12), 10), 
                value = sample(c('A', 'B', 'C'), 120, replace=TRUE))
addmargins(round(prop.table(table(dt$value, dt$month), 1) * 100, 2))
```
