PPTX file (PowerPoint 2007) with table which has a vertical-text header
The attached PPTX file, created by MS PowerPoint 2007 SP3, contains a table where the first line of the table (the header) is rotated anticlockwise by 90 degrees (vertical text).
In LO 18.104.22.168 and 22.214.171.124, the text shows up unrotated (horizontal).
Thanks for reporting the bug.
