Centering text in columns/cells

Hi Ian, the new version looks really really good, nice work.

However, I think I found a couple of glitches which I wanted to share with you :

1. I cannot get the horizontal alignment to stick. I select a cell, right click, set center alignment, but UPDATE removes it.
2. I can no longer set Column Width – I would like to be able to do this
3. Duplicate seems to copy only the column headers not the data
4. I think the first time I update a table created with the previous version it erases all the data – I’m going to check this again now

Thanks
