# Overrides the base Kramdown converter to add any special

# Currently we support an option `html_tables` that outputs
# an HTML table instead of a Markdown table. This is to
# support possibly being given complex tables, such as from ADF.
#
# Note: this is only an initial implementation. Currently don't
# strip out IALs or other specific kramdown syntax.
