re-ordering, the "find" operation was highlighting the wrong row, fix
it.

 Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match.
 Refer to Python documentation for the regular expression syntax.
 All columns are searched, but only currently fetched rows are searched.
+<p>N.B. Results are found in id order, so if the table is re-ordered, find-next and find-previous
+will go to the next/previous result in id order, instead of display order.
