Stop infinite recursion when generating anonymous table boxes
Update the list of box types to expect directly inside (anonymous) table
boxes to include 'table-column' (in addition to 'table-column-group'
and 'table-caption'.) This fixes the code that looks for an existing
anonymous table section to add a child to so that it doesn't accidentally
try to add the child to the same table box again recursively.
Also drop a couple of lines of code that had no effect in practice.
