I think you are not interpreting what is happening correctly. Column names are
labels used for purposes of referring to the data in your R code. That they
might also be useful in presenting data in output is coincidental. The fact
that many data input functions replace spaces in those labels with periods
should convince you of this fact.
On the other hand, the options available when you output that table usually
depend on where you want to display the result, which you have not mentioned.
For example the tables package has many options for labeling columns if you are
generating HTML or LaTeX output. Or, you could write your own function to
generate any output format you want.
