ExtJS4 Displaying Nested Model in Grid with Grouped Header?

You cannot group headers in extjs. You can, however, group them as in this example docs.sencha.com/ext-js/4-0/#!/example/gr....

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
