You're correct; we have not yet added a special syntax to our wiki system for creating tables.
Oftentimes, it is best to present data in an alternate format; tables do not necessarily format well, particularly on mobile devices. However, I have been known to use [http://www.dozuki.com/Help/Advanced_Wiki_Formatting#Section_Code|the code tag] to create table-like structures:
[code]
-----------------------------------
| Heading 1 | Heading 2 | Heading 3 |
|-----------------------------------|
| some data | some data | some data |
|-----------------------------------
[/code]
Here's how I did that:
[code]
[code]
-----------------------------------
| Heading 1 | Heading 2 | Heading 3 |
|-----------------------------------|
| some data | some data | some data |
|-----------------------------------
[/code]
[/code]
This method is a bit fragile, in that you may need to adjust an entire column if a cell is too small for the data within it. It does work in a pinch, though.
