Click "edit" to view the code for this table. I created this by copying code from Wikipedia's help section.
Transclusion
Transclude target page, where "Pagename" is the target:
x{x{Namespace:Pagename}x}x
(Remove each "x" to deploy template.)
Note: subsequent pageloads of the page bearing this template will cause a tranclusion of the target page each time the current page is loaded. Changes made to the template are then automatically reflected on all pages into which that page has been transcluded (though a purge may sometimes be necessary).
To prevent deploying the template with every page load, use substitution, as below:
(Do not transclude the code on the ones that originated outside your own user space; it would call up the templates every time and might break if the designer changed the code).
