In Table tool column headings using the table and render tools should offer ability to wrap and justify (horizontal and vertical). right now you can justify a column and the heading may or may not stack (wrap) based on table size and the width configuration in the table tool. I wish you could give a it more control like we have in Excel, for example left justified and wrap for a column heading with blanks separating words results in auto stacking the words based on column width, auto or manual width control.
