You might look at the pages in lib/UI/pages/admin/wizard -- they 
use most of the options of [table-editor] one time or another.

In this case, it should be automatic if you do

	[update values]
	[table-editor table=foo]

If you want to pre-set only if there is not a current value in that
key in the table (my guess):

	[table-editor
		table=foo
		default.field1=`$CGI->{field1}`
		default.field2=`$CGI->{field1}`
	]

You have to use the Perl notation because the hash-based keys of
the default option don't interpolate for Interchange tags.

You can do the same thing with only incoming variables if you do:

	[table-editor table=foo cgi=1]

Then you format a link like:

	[page href=your_editor
		form="
			field1=foo
			field2=bar
			ui_te_default:field1=your default value 1
			ui_te_default:field2=your default value 2
		"
	]Edit foo[/table]

I may at some point write docs for table-editor, which with its
"wizard" mode is really an application in itself. For now it is
supposed to be one of the undocumented things in the UI, of which
there are many.
