PowerPoint-Specific Notes

Font size and underline aren't part of a PowerPoint table style

PowerPoint's own table style format has no slot for font size or underline at all - both live on a single, shared setting for the entire presentation, not per style. This app never reads or writes them for PowerPoint files, for the same reason it doesn't handle cell padding for PowerPoint (see General limitations). Bold, Italic, font color, and font family all work normally.

Cell padding

See General limitations - PowerPoint has no per-style slot for cell padding either.
