I created a customized CKEditor 4.1.2 build based on the Standard Preset; adding
Color Button
Color Dialog
Find and Replace
Font Size and Family
Insert Smileys
Justify
Select All
Table Resize
and selecting the Kama skin. When I expanded the downloaded ZIP file, I see the table and tabletools folders (required for Table Resize) but no tableresize folder as found in CKEditor 3.6.6. I see a tableresize folder in the samples/plugins folder but it contains just an HTML file.
Is the Table Resize code merged into another plugin? Downloading just the plugin shows a tableresize folder and the Drupal CKEditor module is looking for plugin.js within that folder before enabling it..
I have tested with with IE9 and Firefox so I do not think the problem is a cached copy of the downloaded file.
Thanks, Norbert
Further Testing
I did some further testing and believe that the Table Resize code is actually there. Drupal failed trying to load the tableresize/plugin.js. Just looking at the Drupal CKEditor profiles caused Drupal to disable the tableresize plugin because it could not find the folder. However, now that Drupal is loading CKEditor 4.1.2 properly, I see that I can use the mouse to resize columns and adjust the width of the table. Then again, I may just be showing my ignorance of how Table Resize works.
