Add details and advice on what tables packages are best for different purposes

**Is your feature request related to a problem? Please describe.**
A few of us have talked about this, as we've found through trial (and lots of error) that different packages in R work better for some purposes than others

**Describe the solution you'd like**
Probably a new 'tables in R' section that then covers R Markdown into HTML, into Word docs / PDFs, embedding in quarto, and different shiny use cases too

**Describe alternatives you've considered**
Could split up into separate sections, though not sure we have our own guides for markdown yet like we do shiny so probably better all as one on the R page

**Additional context**
We might look at adding wrappers to some packages here in dfeshiny or even shinyGovstyle, so worth checking on the latest on those (currently I think reactable is looking the most promising for this in R Shiny).

There might be some things to steal from here - https://r-graph-gallery.com/table.html, they also have a diagram, which might be good for us to replicate that kind of visual with our own suggestions:


Though you should be warned, @jen-machin may not appreciate it if you copy the font too...
