Hi guys,
We have recently updated Confluence to 4.2 and we noticed that after the change we used embedded excel spreadsheet files on Confluence pages the formatting is looking worse than it was in the previews version...
See screenshots for more details. One is the original file and second two is the view after importing to Confluence.

All data that is using center and right aligment after importing to Confluence it is showing with a left aligment. Other thing is that hide cells are not respecting width. Confluence is cutting in a wrong way example with the dates..

Below is the original file with correct alignment:

We are using Office 2010, but the issue is reproduced also when using 2007 files. We were wondering if this is not a browser specific issues, but it looks like there is no big impact on what browser user is using.
Below is the result of the testing the center alignment and hidden data on different version of Confluence and browsers.

Tested on:
Firefox - 14.0.1
Chrome - 20.0.1132.57
IE - 9.0.8112
Is this a BUG? Can someone reproduce the error and have any idea why this is happening?
Any help would be appreciated
Thanks,
Mirek
