org: Tables in HTML export
12.6.6 Tables
-------------
Org mode tables are exported to HTML using the table attributes defined
in ‘org-html-table-default-attributes’. The default setting makes
tables without cell borders and frame. If you would like to change this
for individual tables, place something like the following before the
table:
#+CAPTION: This is a table with lines around and between cells
#+ATTR_HTML: :border 2 :rules all :frame border
You can also modify the default tags used for each row by setting
‘org-html-table-row-tags’. See the docstring for an example on how to
use this option.
