Paragraph alignment is not displaying correctly when it is used on tables created in previous files, even though you are in a new or an old document. The only way to do it is by using cell insets on the properties tab. So it makes it useless unless you create new tables with new formats. It would be great to fix this bug so the alignments are displayed in the paragraph alignment tab, and make cell insets a new tab so I can see specifically this option on the main windows.
