This project adds a new tab to the Results of a Webform. It provides an Ext JS-based grid to view and directly edit Webform submissions.
As of now, I have only tested this module on Drupal 7.x using Webform 4.x. It might work on Webform 3.x, however.
To use this module, obtain the module directory (webform_extended_table) and contained files and directories (via git) and place in your sites/all/modules directory.
Since this module also requires Ext JS to render the table, you must download that separately from the Sencha Ext JS site. I have only tested the module against Ext JS ver. 4.2.1. The download from Sencha will contain a top-level directory named ext-4.2.1.883 (or some equivalent). Place that directory in your sites/all/libraries folder, and rename that top-level directory "extjs".
Once the module is enabled, create a Webform with submissions. Then in the admin, go to the Webform and click on the "Results" tab. There you will find a new sub-tab named "ExtJS - Table". Click on that sub-tab to view and edit the submissions in an Ext JS dynamic grid. You must be logged in with proper permissions for viewing and editing to use those functionalities.
