The CGridView widget is very useful and customizable, but sometimes you need a little more.
One limit I found is to have only one row for headers; yes, you can write each column header in more than one row, but just inside the single cell.
I was looking instead for the possibility to use more than one row, with different structure one from the others.
This way you can write columns grouping headers, and obtain a nicer view.
If you are lucky enough and have the privilege to develop on a Linux based environment, this little tip might boost-up your TDD process (at least the Unit Testing part). Please note, that this should work just fine with Apple computers also, but not tested!
Lots of people are asking how to solve it with YII,We think its difficult with YII. But its easy to solve . There is no database triggers needed . we can simply sove it by extending a class(say "RActiveRecord") from CActiveRecord .Then extend all our model classes from that class.
