Ext.ux.RowExpander how to place a panel inside a table (solution)

Not so long ago, I wrote about a plugin allowing to place a panel inside a table. The plugin is very interesting and does not eat a huge amount of resources, but with a slight drawback. It cannot work normally with EditorGridPanel.
So, I asked for help here, but somehow no one responded, so I still climbed the forums, then I found a developer, etc. In general, the solution was found and under the cut the actual answer to the question - how to make RowPanelExpander work with EditorGridPanel?

On the link you can find the plugin and an example of its work: Click
