Table: Insert Column Before and Insert Column After not working when a column contains some 'undefined' cells

[Teresa Monahan]

Steps to Reproduce:

1. Open any CKEditor sample and paste the following into source view:

<table border="1" cellpadding="1" cellspacing="1" style="width: 500px;"> <tbody> <tr> <td> 1.1</td> <td> 1.2</td> </tr> <tr> <td> 2.1</td> <td> 2.2</td> </tr> <tr> <td> 3.1</td> <td> 3.2</td> </tr> </tbody> </table> 

2. Switch back to wysiwyg mode and right click in the cell labeled 2.2
3. Select Cell -> Insert Cell After from the context menu. The 2nd row in the table should now have 3 cells.
4. Right click in the new cell and select Column -> Insert Column After.

Problem: The column is not inserted and a script error occurs.

The error is:

P[S] is undefined
http://nightly.ckeditor.com/7334/ckeditor.js
Line 86

When run using ckeditor_source.js the error is:

cloneCol[i] is undefined
file:///C:/ck%20test%20builds/3.6.2_dev/_source/plugins/tabletools/plugin.js
Line 292

The code in insertColumn() in tabletools/plugin.js tries to check the colspan of each cell in the column but 2 of the cells in the new column are undefined - therefore the error is thrown.

Reproducible in all browsers from CKEditor 3.5.1 rev [6328].
