You can import getable’s default Rmd template with in RStudio by selecting: File > New File > R Markdown > From Template > HTML Tables with Dynamic Data {GETable}

This will generate a folder. You can then open the Rmd source file and edit the document. Note that the relative path of the dependency files (*.html, *.js, and *.css) to the source Rmd must stay constant for the package to work.

See demo for a working example.
