Bugs in ZMSTable

We have some troubles with the new editors interface of ZMSTable

- We migrated content with ZMSTables from an 
older ZMS-Version to ZMS 2.11.0-34 (Build #131d)
Some of the tables where broken after the migration:

[...]
return render_blocks(self.section, md)
File "/opt/zope/zope/lib/python/DocumentTemplate/DT_In.py", line 634, in
renderwob
raise ValueError, (
ValueError: Strings are not allowed as input to the in tag.

and in the table edit view above the first row the percent-values are
broken ([% Z% instead of 13% 86%)

To repair them, someone has to open the tables and save them again. But
this approach DOES NOT WORK WITH IE7. It works with Firefox indeed.

But with Firefox (2.x) there is an other problem. The text-field which
pops up after a double click does not write back changes.
