I got this extension for a sports site I'm running and it turned out that Tabulizer is much more flexible than I was expecting at first glance. The basic idea is that you create styling templates that you can use for all tables you add to your Joomla articles afterwards. Even though there is documentation on how to create your own styling rules, the total lack of any CSS/HTML knowledge of my behalf, led me to ask help from a web designer in the office. After an hour he sent me 13 templates (or "rulesets" as they are called), one for each league I'm covering. Now I can copy-paste all the league results tables from Word (where I keeping them for the printed version of the newspaper) to Joomla in less than 5 minutes (compared to 45-60 minutes it took me previously). So, I'll definitely recommend it if you are copying tables from Word to Joomla regularly.
* Easy to use
* You can use the pre-installed styling rules or create yours.
* To take full advantage of this extension, CSS knowledge is expected (at least minimum)
* Joomla 1.6 is not support (yet)
