Re: status of PPT Tables support in POI-HSLF

[stargate625 <st...@gmail.com>]

I used the latest release of Apache POI to create a PowerPoint file with a
table.  The problem I encountered was that the table could not be displayed
correctly using my PowerPoint 2003.  The text in the table cells was based
on the default font and large size and bulleted list.  I tried to change the
font and size using the RichTextRun from each table cell.  My settings
didn't seem to have any effect.

Is this problem solved in Apache POI?
