Thread:Project:Support desk/data tables/reply

Those tables are created using Wiki Syntax, specially tables (see Help:Tables).

Instead of putting the code for that table on every page, you should normally put that on a template (see Help:Templates) and include that template on your pages, filling the necessary template parameters with the information that varies from page to page.

You can see Wikipedia templates for an example, although wikipedia ones are overkill, so you may want to check other wikis for simpler ones first ;)
