templatelinks表

MediaWiki版本：

≥ 1.6

templatelinks表含有当前每个有嵌入引用的托管页面ID、所包含页面名字空间编号、无名字空间的标题。

目标页面可能存在或不存在，因时间推移可能已重命名或删除而引用了不同的页面。

Despite the name, transclusions are not limited to templates, nor to the MediaWiki parser's transclusion mechanism; various extensions use this table to mark that they have incorporated content from another page. (E.g. Scribunto 's {{#invoke:...}} and TemplateStyles 's <templatestyles src="..." /> both record the target page in the templatelinks table.)
