Description:
Workbench allows the "Alter Table" tab to be opened more than once for a given table.

I have a class with 250+ students using Workbench - we find that Workbench can get confused (and the students) as a change made in one Alter Table instance is not propagated to other instances. 

How to repeat:
Click a table on the left hand pane, right click, press Alter Table

Do the same again.

Suggested fix:
Check to see if a Table Editor for that table is already open, and if so, simpy switch to that particular dialogue. There is only one instance of that table in the database, so it doesnt make sense to be editing it in multiple ways in different tabs.

Thank you for the bug report.
