Now that vBulletin has a table syntax I've removed our old ATABLE plugin (which was very slow).
Here is an example of what you can do...
Heading 1 Heading 2 Row 1/1 Row 1/2 Row 2/1 Row 2/2 Row 3 span
The syntax is similar to HTML
[TABLE="class: grid, align: center"] [TR] [TD][B]Heading 1[/B]
[/TD] [TD][B]Heading 2[/B]
[/TD] [/TR] [TR] [TD]Row 1/1
[/TD] [TD]Row 1/2
[/TD] [/TR] [TR] [TD]Row 2/1
[/TD] [TD]Row 2/2
[TR] [TD="colspan: 2"][CENTER]Row 3 span[/CENTER]
[/TD] [/TR] [/TABLE]
Another way to post a table is to edit it in MS Word and copy/paste from there.
