Hi Blake,
here are the rules:
- column widths are measured unless specified
[tbl(1), second paragraph below "Table data"]
- measurements result in at least 1n [undocumented]
- column separations default to 3n unless specified
[tbl(1), last but one paragraph]
- "\_" extend from the beginning of the column to one beyond the end
- "_" extend half into the separation on either side, rounding up
[both in tbl(1), third paragraph from the end in "Table data",
but somewhat fuzzily, neither explaining the "one beyond the end"
nor the "half rounding up" exactly]

number of columns: 5
widths (measured): 3 1 3 1 3
separations (default): 3 3 3 3
rulers into sep's: 3/2 = 2
consequently:
columns with data: 1>3 11>13 21>23
separations: 4>6 8>10 14>16 18>20
rulers: 1>3+2 11-2>13+2 21-2>23+1

It isn't. There is a second, empty column and two separations.

It is left justified and it hasn't padding on either side.
The "_" rulers extend half into the separations on either side.
> The third column had no padding on the right, but does on the left.
No padding here either.

number of columns: 3
widths (measured): 3 3 3
separations (default): 3 3
rulers into sep's: 0 left, 1 right
consequently:
