Folks this is the big one.  The table is a full 2" thick butcher block.  It is so heavy it must be supported in the middle with a center leg.  The table without the leaves installed is 42" wide x 66" long.  It comes with three 18" long leaves so you can expand the table to 84" long, 102" long, or add all three for a 120" long table.
 
42" wide x 66" long w/ three 18" leaves extends to 120" long
