Table BB-Code - Dangerous
Hard to use and style-breaking
Currently, using the TABLE BB-Codes requires using all three of TABLE, TR, TD. This can be confusing for beginners and those with little HTML experience. Also, there is no failsafe mechanism so even experienced users can make broken tables by accident when working with large tables, and break the entire table layout of vBulletin.
Converting from Legacy Table Code to VaultWiki table code is not straightforward, and there appears to be a loss of functionality since the Legacy Tables, with respect to table properties and design.
