手册:math表
↑ 手册:索引 | MediaWiki数据库布局 | math表 |
The math table was used by the math module to keep track of previously-rendered items.
This table is not used in the MediaWiki 1.18 release, and can be safely deleted.
It was, and still is used as part of Extension:數學 , however, no core software needs it.
