Hi,
when discussing [0], a question arose. When phpMyAdmin thinks that there are no rows, some tabs are greyed out. However they can still be clicked , because by the time the page has been displayed, another process might have written some rows to this table.
But clickable greyed out tabs is confusing for some users. Let's decide about this (for 4.1):
1. no longer grey out
2. grey out but not clickable
3. status quo
