Bug with automatic alignment of table columns in HTML export

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.

Emacs  : GNU Emacs 24.1.1 (x86_64-pc-linux-gnu, GTK+ Version 2.24.12)
  of 2012-09-22 on batsu, modified by Debian
Package: Org-mode version 7.9.4 (7.9.4-dist @ 
/usr/share/emacs/site-lisp/org/)

Fixed, thanks.

You're quite welcome. That was prompt! I see this case now works in 
master. The catch is that there are still some cases which give 
inconsistent alignment between Emacs and HTML export, such as:

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

I believe the heuristic used for in-buffer display is that empty cells 
are ignored entirely when doing the comparison against 
org-table-number-fraction.

For such cases, you can use this:

| <r> | <r> |
|   a |   b |
|-----+-----|
| 100 |   1 |
|   1 |   1 |
|   1 |   1 |
|   1 |   1 |
|   a |   1 |
|     |   1 |
|     |   1 |
|     |   1 |
|     |   1 |
|     |   1 |
|     |   1 |

HTH,
