I don't understand why I can't get the following table examples to format correctly when using the knitr and markdown packages in RStudio. In each case, the content below the column headings is fine, but the column headings are always left aligned no matter what formatting is used.
Here is my test .Rmd file based on the examples from the Markdown help files at
http://pandoc.org/README.html#tables
and
http://rmarkdown.rstudio.com/authoring_pandoc_markdown.html#tables

# Table tests

spans multiple lines.

the blank line between

## Piped table
| Right | Left | Default | Center |
|------:|:-----|---------|:------:|
| 12 | 12 | 12 | 12 |
| 123 | 123 | 123 | 123 |

## cat() table
This is another option that I found [here](https://stackoverflow.com/questions/19997242/simple-manual-rmarkdown-tables-that-look-good-in-html-pdf-and-docx?rq=1), which _should_ work well under many formats .
```{r, echo=FALSE, results='asis'}
tabl <- "
| Tables | Are | Cool |
|---------------|:-------------:|------:|
| col 3 is | right-aligned | $1600 |
| col 2 is | centered | $12 |
| zebra stripes | are neat | $1 |

cat(tabl)
```
