Remove "compatibility" features from Table.java

In the recent cleanup that introduced Table.java, some "compatibility" features were added to paper over the differences in the various tables generated by the old code.

The compatibility features were added to minimize the churn to the tests, to facilitate before/after testing of the new Table.java code.

Now that Table.java has been in use for a while, we should remove the compatibility features, so that all the generated tables are generally consistent in their appearance and properties.
