Thanks very much for taking time to answer my question. How do you
add either the "From" or "Organizer" field to the table headers?

FIeld Chooser. RIght-click the header line, select Field Chooser. The
"Organizer" field will be on the "All Appointment Fields" select of the
drop-down for some views and the "From" will be on the "All Post Fields" or
"All Mail Fields" drop-down for other views.
