When creating a table, I was noticing that the
<colgroup><col>... provides useful alignment information based on
whether or not the column has numbers in it.  I think, however, that
there is a mistake in this routine.  Take, for example, the following
table:

|  Id | Task         | Developer | Estimate | Spent | Remaining | Comp.% 
| Updated         |
|-----+--------------+-----------+----------+-------+-----------+--------+-----------------|
|   1 | Task One     | SLP       |        1 |     0 |         1 |      0 
| SLP, 2010-04-27 |
|   2 | Task Two     | SLP       |        1 |     0 |         1 |      0 
| SLP, 2010-04-27 |
|   3 | Task Three   | SLP       |        2 |     0 |         2 |      0 
| SLP, 2010-04-27 |
|   4 | Task Four    | SLP       |        2 |     0 |         2 |      0 
| SLP, 2010-04-27 |
|   5 | Task Five    | SLP       |      .25 |     0 |      0.25 |      0 
| SLP, 2010-04-27 |
| 5.1 | Another Task | XML team  |        0 |     1 |         0 |      0 
| SLP, 2010-04-27 |
|   6 | Task Six     | SLP       |      .25 |     0 |      0.25 |      0 
| SLP, 2010-04-27 |
| 6.1 | More Tasks   | DB team   |        3 |     0 |         3 |      0 
| SLP, 2010-04-27 |
|   7 | Task Seven   | SLP       |        3 |     0 |         3 |      0

When the colgroup list is created for this table, it reads:

<colgroup><col align="right" /><col align="left" /><col align="left" 
/><col align="right" /><col align="right" /><col align="left" /><col 
align="left" /><col align="left" />
</colgroup>

Note that the first columns are correct, but the last few are not.
It should read right, left, left, right, right, right, right, left.

I believe that this is due to the (< i nline) comparison within 
org-format-org-table-html, which is nonsensical because it's trying to 
compare a column number with a number of rows.  I've attached a patch 
for the problem.
