I used Tabulizer for an intranet site that my company is developing in order to share data among employees. My job was to transfer data from MS Word tables to html tables in Joomla articles. Not having experience with HTML and CSS styling, I was having trouble copying and formatting tables from MS Word. Then, a colleague of mine installed Tabulizer and created a table template for me (called a ruleset) and now I can copy tables from Word in seconds instead of minutes! I highly recommend this extension to anyone that works a lot with tables in Joomla articles.
