I recently spent some time rummaging around trying to figure out how to use the table formatting option.

There might be an explanation somewhere, but I couldn't find it. So here's how:
Arrange your text one line per row with the "|" character separating the columns. The first line will be the headers.
Example:
Header 1|Header 2|Header3
a|b|c
1|2|3
Then just highlight the area and click on the "Table" icon.
Your edit window will look like this
HTML Code:
[TABLE]Header 1|Header 2|Header3
a|b|c
1|2|3[/TABLE]
now hit "Preview Post", and Voila, the table appears in the preview window.
Header 1 | Header 2 | Header3 |
a | b | c |
1 | 2 | 3 |
