Comparison Tables Made Easy – CompareNinja
CompareNinja is a free-to-use web application for generating comparison tables very quickly.
It simply requires several variables to get started like "the title of the tables" or "number of items to be compared" and then asks for the details of the comparison.
There are few skins provided to choose from, new columns and rows can always be added and the HTML output is generated instantly.
After that, you can always edit the source and improve the table further.
And, yes, creating tables is not hard but, sometimes, a quick method that doesn't require any web editor is handy.
