A cell in a table has a certain area, x pixels by y pixels, which depends on 
the flags you used to create it.  If you pack a widget which is smaller than
x by y pixels into that cell, it won't take up all the space in the cell, 
instead being left-justified and top-justified (I think this is this correct), 
with empty space to the right and bottom of it.

With GTK_EXPAND in the xoptions arg to gtk_table_attach(), this widget
would be centered in the cell, with even amounts of space on the left
and right of it within the cell.

With GTK_EXPAND in the yoptions arg, this widget would be centered in the cell,
with even amounts of space on the top and bottom of it within the cell.
