So I am trying to achieve the same thing as the OP of this thread wanted [1]. Basically, to get "green" color for "yes" and "red" color for "no" in the cells just like a standard comparison table on the Internet Wikipedia [2]. So I defined my table (simpliefied example) in the wiki page as follow: {| cellspacing="0" cellpadding="3" border="1" class="wikitable sortable" |- ! A ! B |- | {{Yes}} | {{No}} |} Obviously nothing happened with the above code i.e. I did not get any green or red background color in the cell. In an expected manner wiki engine displayed "Yes" and "No" with a "wanted link". Now I am not sure if I have to create Templates called Template:Yes and Template:No? And if I do have to create these templates, what should be the content of those templates? I am using MediaWiki 1.12 version.
