Table Tools spanning not updated

[Eugen]

Testcase:

Use IE or FF to be able to easily visualize the issue, in the source its broken for all browsers thogh

1. Go on ​http://ckeditor.com/demo
2. Create a table with 4x4
3. select Cell 1x1 and set row-spanning to 10
4. You now have a broken spanning since it is not validated

A more common use-case for normal users would be

1. Go on ​http://ckeditor.com/demo
2. Create a table with 4x4
3. 3. select Cell 1x1 and set row-spanning to 10
4. Delete a row -> spanning is not set to 9, instead of getting recoundet and fixed

Basically there is no sense in not validating the data since this is an editor for a user, not developer. In a table with a lot of rows you can easily count wrong and end up having a broken table.

Solution:

a) caluculate max span for col/rowspan before entering the dialog and offer a select-widget rather then an input field b) validate on save

You could also reuse such a table validator: ​http://jsfiddle.net/UkV35/8/

Thanks for the validation code snippet. We will definitely need to introduce something like that for tables.
