Extjs 4 nest grid or sub grid demo

The plug-in rowexpander is used for grid Nesting. This plug-in is available in ext4.2.2.1144.

Implementation focus

1. nest grid cannot respond to many events. Otherwise, an exception will occur and enter the getHeaderIndex: function (header) function ).

 innerGrid.getEl().swallowEvent([                    'mousedown', 'mouseup', 'click',                    'contextmenu', 'mouseover', 'mouseout',                    'dblclick', 'mousemove'                ]);

Ii. added the menuDisabled: true, resizable: false attribute when column is defined to prevent some interface appearances that do not seem to conform to common sense.
