   # between the elements.  This is necessary because DOM parent-child-sibling
   # relations can change and screw up the javascript for restoring, collapsing
   # and expanding.  Do not change without testing all three of those.
+  # Also, the first empty row is required because 'table-layout: fixed' only
+  # considers the first row to determine column widths. If a colspan is found,
+  # it then share the width equally among all columns, which we don't want.
