The HTML export backend uses org-html-table-default-attributes when
exporting Org tables to HTML. By default, the exporter does not draw
frames and cell borders. To change for this for a table, use the
following lines before the table in the Org file:
#+CAPTION: This is a table with lines around and between cells #+ATTR_HTML: :border 2 :rules all :frame border
The HTML export backend preserves column groupings in Org tables (see Column Groups) when exporting to HTML.
