How a multi column textbox roundtriped in Impress looks in PowerPoint
Textbox with PPTX with columns are now converted to tables. When those tables are saved, they are not borderless, so lines appear around your text when opened in PowerPoint, but not Impress.
Steps to reproduce:
1. Open a PPTX with multiple columns in Impress, such as attachment 114222 [details]
2. Save as PPTX
3. Open in PowerPoint
No borders like Impress
There are borders around the columns

So, the borders were introduced after http://cgit.freedesktop.org/libreoffice/core/commit/?id=aef569ed83a3ccc02639e5b2a1c7cc131ba262fc, before that, the two columns were displayed on the same columns without border. I don't know if we should consider this a regression... Miklos ?
Nah, it's just a bug. :-) Before: table borders were missing as the whole table was missing. After: formatting of the border needs fixing.
But sure, it needs fixing, I'm not arguing there.
