Each column can have it's own font, font size, and justification.

The formatting controls are directly to the left of the Printer icon.  They remain greyed out (disabled) until a column name is selected.  The figure below shows the formatting controls disabled because no column names are selected.

Click on a column name and the formatting controls become active.  Click on one of the top three icons to set the column justification.

Select the column's font and font size from the respective pop-up menus.
