Rmarkdown side-by-side tables spacing

Question

I'm trying to print two table side-by-side through Rmarkdown, output as PDF.

I can print the tables out fine, but they end up stuck really close together and I cannot find a way to create more space between them. The solutions I find in other posts returns strange output or errors, e.g. the second one from here just gives an 'error 43': Align multiple tables side by side

My code is this:

```{r, echo=FALSE}
library(knitr)
kable(list(head(bymonth),head(bydecade)),align='c')
```

Anyone know how to add some spacing between those two tables?

Answer 1

Incorporating the answer given here you could do it manually like this:

```{r, echo = FALSE, results = 'asis', warning = F}
library(knitr, quietly = T)
t1 <- kable(head(mtcars[,1:2]), format = 'latex')
t2 <- kable(head(mtcars[,3:4]), format = 'latex')
cat(c("\\begin{table}[h] \\centering ", 
      t1,
    "\\hspace{1cm} \\centering ",
      t2,
    "\\caption{My tables} \\end{table}"))  
```

The basic idea is to create the tables individually and align them with plain latex. The spacing is added by \\hspace{1cm}.
