Manual:math table
(Redirected from Math table)
| ↑ Manual:Contents | MediaWiki database layout | math table |
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:Math, however, no core software needs it.
