[O] Bug with automatic alignment of table columns in HTML export

[Kodi Arfer]

Consider an Org file with the following content:

|   a | b |
|-----+---|
| 100 | 1 |
|   1 | 1 |
|     | 1 |
|     | 1 |
|     | 1 |
|     | 1 |
|     | 1 |
|     | 1 |

Within Emacs, Org right-aligns the left column, as it should, since most 
nonempty cells in the column are numeric. In HTML export, though 
(starting from "emacs -Q -l /tmp/minimal-org.el"), the column comes out 
left-aligned. The problem seems to be with how the exporter treats empty 
cells, since if you put numbers in all the empty cells above, the column 
comes out right-aligned in HTML export.
